Innovation for All
The discovery of new medicines has far-reaching benefits Russell Williams
T
he Wright brothers’ historic maiden flight lasted only 12 seconds and travelled 120 feet. Of course, aeronautic research didn’t end there. There have been hundreds if not thousands of incremental advances, and now jet travel and transatlantic flights are routine. The same concept applies to the discovery of new medicines. We recognize insulin as a Canadian innovation, a medical breakthrough that aids diabetics around the world. The overall treatment of diabetes has significantly reduced the mortality rate of this condition since Frederick Banting’s discovery of insulin. New medicines help Canadians live longer, healthier, and more productive lives. For example, hospitalization rates over the period 1983–2001 for ulcers decreased by 75 percent. For HIV/AIDS, the decrease was 71 percent. Diabetes hospitalization dropped by 44 percent while respiratory diseases and chronic liver disease dropped by 44 percent and 31 percent, respectively. The introduction of a series of new medicines to treat the same disease serves to advance the treatment of illness while providing novel, therapeutic benefits to existing therapies. What works well for one patient may be less effective for another based on age, sex, overall state of health, and other factors. It is essential that patients have a choice. Medical science and patient care are advanced through incremental innovation. These new medicines are chemically different and not duplications of other medicines in the same therapeutic category. Providing physicians and patients with a choice of medicines in a particular therapeutic category helps save health care dollars by avoiding unnecessary hospitalization and surgery. Over the last two decades, pharmaceuticals have contributed greatly to the dramatic 70 percent reduction of the death rate of HIV/AIDS. Similarly, death rates from heart attacks have decreased by 63 percent;

bronchitis, asthma, and emphysema by 71 percent; and chronic liver disease by 45 percent. Prescription medicines are also one of the most cost-effective and least expensive resources for patient care. A study by Columbia University has estimated that for every dollar invested in newer medicines, six to eight dollars are saved in other parts of the health care system. The patented medicines portion of health expenditures in Canada in 2004 is less than seven cents of Canada’s health care dollar, while the prices of patented medicines in Canada declined over the past decade and remain 9 percent below the international median. With all the evidence that new medicines benefit patients, still the main focus of policy discussions is on restricting access and cutting costs. Patient outcomes seem to be secondary in the debate. The current categorization system of the Patented Medicine Prices Review Board (PMPRB) fails to recognize incremental innovation that could significantly impact on health outcomes for patients. Rx&D believes Canadians could benefit from improvements to the board’s scientific review procedures and categorization of drugs to recognize the value of new medicines. The goal is improving patient outcome. The research-based pharmaceutical community is committed to working with scientists, governments, and health care stakeholders to ensure Canada has an affordable, equitable, and sustainable publicly funded health care system.

presence. Normal switches are gaps in wires that disrupt the flow of an electrical transmission, but biosensor electrical switches are shaped like pockets. Whether or not they conduct electricity depends on the pocket’s conformation. Researchers on this project include Tito Scaiano, FCIC, department of chemistry at the University of Ottawa, and from SFU—Dipankar Sen, MCIC, department of molecular biology and biochemistry/chemistry; Hogan Yu, MCIC; and graduate student Marcus Kuikka, MCIC, from the department of chemistry. “We’re developing DNA pockets with specific angles that will trap specific target molecules,” says Bechhoefer. “As the target binds, it will restore the electrical conductivity in the pocket, acting as a switch.” Scientists have previously shown that DNA conducts electricity. But unlike traditional conductors such as copper, DNA’s conductivity changes depending on what it’s bound to and what surrounds it. Bechhoefer is using this feature to his advantage. The pockets he envisions have a particular shape and size that depend on the DNA strand’s length and composition. And they’ll conduct electricity only when a target molecule binds and flips the DNA switch. But this switch isn’t very useful if it’s just DNA in solution, he says, because such switches aren’t usually part of physiologically important electrical circuits. So he’s using the DNA as if it were a wire. By surrounding DNA with a surface of insulating molecules, he hopes to conduct electricity between two gold particles (introduced by researchers in test situations) connected by DNA. Bechhoefer anticipates certain advantages to using DNA sensors. Besides being Biosensors—tiny devices that can detect highly sensitive and accurate, they’re ecobiological molecules—built with specially nomical because there’s no need for expenengineered DNA strands may one day advance sive cameras to observe them and no risk of scientists’ ability to detect a wide variety of molecules losing their fluorescence.

Canada’s First Private Brownfields Fund Launched A $100 million private equity venture has been dedicated to cleaning up contaminated real estate. The Kilmer Brownfield Equity Fund is Canada’s first brownfield fund, courtesy of Kenneth Tanenbaum, whose family has been involved in Canadian construction for three generations. Tanenbaum ran Lafarge North America Inc. and his father is chair of Maple Leaf Sports and Entertainment Ltd. The family holding company, Kilmer Van Nostrand Co. has committed $20 million toward the fund. According to Tanenbaum, the approach will be to clean up contaminated land, potentially re-zone it, and then sell to developers. The fund comes on the heels of Ontario initiatives and legislation clarifying owner liability to encourage the redevelopment of industrial lands. Tanenbaum will manage the fund with the help of three managing partners who are experts in environmental science, real estate development, and finance.

intended exclusively to support research projects of the NMR research community and their academic and industrial collaborators. The uniqueness of the facility is that it is dedicated to solid-state NMR research in materials, where advantages of the highest magnetic fields are most striking, especially for quadrupolar and low-gamma nuclei such as 17-O, 25-Mg, 35-Cl and others. The 900 MHz instrument in Ottawa is the latest generation digital Avance II NMR spectrometer manufactured by Bruker BioSpin and is equipped with a number of solid-state NMR probes, for both magic angle spinning (MAS) and static, capable of wide range of multinuclear NMR experiments. In collaboration with Bruker BioSpin, work continues on development of solid-state NMR probes for very low-gamma nuclei. The official opening ceremony of the facility is scheduled for June 1, 2006, and will be followed by the inaugural Solid-State NMR workshop. More information about the facility and on how to apply for instrument time is available at www.nmr900.ca. University of Saskatchewan

Canada’s Most Powerful NMR Spectrometer Nuclear Magnetic Resonance (NMR) spectroscopy is widely used in chemistry for structural analysis. Performance of NMR spectrometers greatly depends on homogeneity and strength of the magnetic field. The early NMR spectrometers operated at moderate magnetic fields of about 0.5–1 Tesla (T) created by solenoid electric magnets. Advances in superconducting magnet technology led to the development of NMR spectrometers with considerably higher magnetic fields. Modern NMR spectrometers use magnetic fields ranging from 5 to 16 T. The limit of the current NMR technology is at 21 T, which corresponds to 900 MHz—the resonance frequency for protons. The higher the magnetic field, the more complicated the magnet design becomes with hardware and maintenance costs rising exponentially. At the moment

there are only a few NMR spectrometers in the world operating at 21 T. Thanks to the collaborative efforts of researchers from the National Research Council Canada, the University of Ottawa, and other universities from across the country, Canada’s first 21 T (900 MHz) NMR spectrometer has been recently installed in Ottawa, ON. This spectrometer is part of the National Ultrahigh-field NMR Facility for Solids, a national scientific user research facility funded by the Canada Foundation for Innovation, the Ontario Innovation Trust, Recherche Québec, the National Research Council Canada, and Bruker BioSpin, and managed by the University of Ottawa. The facility has been created to provide Canadian researchers access to the new 900 MHz NMR spectrometer.

Canada to Build New Nuclear Reactors Ahead of U.S. New nuclear reactors will likely be started in Canada before the U.S., according to Patrick Tighe, vice-president markets and business development at Atomic Energy of Canada Limited (AECL). Tighe told the Platt’s energy conference in Washington on February 14, 2006 that the Ontario government’s commitment to close its coal-fired generating stations would lead to a significant shortage of electricity in the province. Tighe noted that financing and construction of nuclear power plants has changed greatly over the years. Now, nuclear power plants are built to fixed budgets and time tables on a turnkey or partial turnkey basis. Nevertheless, he said, if Ontario needs new nuclear reactors in service by 2015, it has to start the process now. Canadian Nuclear Association

CPI Plant Start-Ups Strong for 2006 Plans are in the works for the start-up of 33 grassroots plants in the chemical processing industry (CPI) in the U.S. and Canada during 2006. This will be an increase of 18 percent over the reported start-ups in 2005, according to research by Industrialinfo. This small increase in new and grassroots plants reinforces the industry’s confidence that 2006 will be another strong year for growth and increased capital spending. The 33 new plants will represent an estimated total investment value of US$630 million in new investments and will equal over 1,600 new job opportunities. The largest of the new plants starting up in 2006 will be in Canada—the grassroots 71 million standard cubic feet/day (MMscfd) hydrogen plant nearing completion in Edmonton, AB. Construction began in 2004 and commercial operations are scheduled to begin in the second quarter. Next in line is DuPont’s US$50 million grassroots 1,3-propanediol plant, slated to start up later this year. Another factor supporting the idea that 2006 will be a strong year for capital spending is the plan for an immediate expansion of at least one plant starting up this year.

Partnership in Pulp and Paper Research Paprican, the Pulp and Paper Research Institute of Canada, and IPEF, the Institute of Forest Research and Studies of Brazil, signed a memorandum of understanding (MOU) to build a partnership in pulp and paper research. The purpose of this MOU is to set out the framework for cooperation between Paprican and IPEF in order to establish a precompetitive research consortium to serve the needs of the Brazilian pulp and paper industry. During the next three years, the parties expect to demonstrate the feasibility and mutual benefits of this partnership for the industry in Canada and Brazil, and establish a
governance structure for the consortium and the long-term partnership with Paprican. Paprican and IPEF both recognize the importance of basic and applied research and technology transfer through a consortium model and were accompanied in building this partnership by the Brazilian Pulp and Paper Technical Association (ABTCP). The development phase is expected to be completed by December 2006. During this time, input from industry leaders and other stakeholders will be sought for a pilot research program. Current IPEF members will be solicited, as well as other Brazilian and South American pulp and paper companies, universities, and other interested parties. University participation in this venture will be led by the Universidade de São Paulo. The resulting pilot research program will have a duration of approximately two years. The bulk of the work will be performed by Brazilian university partners in collaboration with Paprican researchers. “Paprican is internationally recognized for the excellence of its research, as well as its strong partnerships with industry and universities,” said Luiz Ernesto George Barrichelo, president of IPEF. “We are very pleased to partner with them and believe that they have the potential to play a key role in the development of a strong pre-competitive research program in Brazil.” “Globalization is a key issue and the development of strategic research partnerships with major industry consortia ensures that we stay at the leading edge of pulp and paper research and development,” said Joseph D. Wright, FCIC, president and CEO of Paprican. “This new agreement fits within the framework of our business plan and is in line with our commitment to ensure that we remain in a leadership position to deliver the full potential of available knowledge and expertise to our members and customers. By partnering with IPEF, we are establishing the basis for a long-term relationship with Brazilian scientists, researchers, and pulp and paper producers. We expect that this new strategic alliance will lead to research synergies between our organizations, open new markets for existing Paprican technologies, and generate new sources of revenue for both our institutes,” concluded Wright.

Year-end data for 2005 is now available from Statistics Canada. The data below relates to shipments, imports, and exports expressed in dollar values. Dollar value data for selected chemical industry groupings are shown. More detailed data can be found on the Industry Canada Web site at www.strategis.ic.gc.ca/ chemicals. Despite significant economic challenges related to escalation in the value of the dollar, high energy prices, and feedstock outages, this data suggests that the industry generally fared well during 2005. Total industry shipments and exports were both up compared to 2004. The same is true for most sub-industry groupings. For comparison, total manufacturing recorded growth of 3.1 percent for the year so chemicals grew faster than the all-manufacturing average. Sub-industries within chemicals that showed stronger growth than the overall chemical industry average were: petrochemicals— synthetic resins, fertilizers, adhesives and sealants, explosives, and other chemical products. A number of sub-industries experienced declines in shipments compared to 2004. These were: synthetic fibres, pesticides, soaps and detergents, and toilet preparations. All values are in $ billion. The percentage change compared to 2004 is shown in brackets.

Dow Signs Global Charter and Endorses ICCA The Dow Chemical Company recently recommitted its support to Responsible Care™ when Dow’s president, CEO, and chair-elect signed the Responsible Care global charter, a document that considers the evolving challenges for the chemical industry. Dow also endorsed the global product strategy, an effort by the global chemical industry to further improve its product stewardship efforts. Responsible Care is the global chemical industry’s environmental, health, and safety (EH&S) initiative to drive continuous improvement in performance. It aims to meet and exceed legislative and regulatory compliance, and adopt cooperative and voluntary initiatives with government and other stakeholders. The global charter, developed under the auspices of the International Council of Chemical Associations (ICCA), addresses topics such as the growing public dialogue over sustainable development, public health issues related to the use of chemical products, the need for greater industry transparency, and the opportunity to achieve greater harmonization and consistency among various national Responsible Care programs. The global product strategy developed by the ICCA guides the industry’s long-term efforts to meet the global challenges of chemical products. It includes development of guidelines for product stewardship, a tiered process for risk characterization and management, focus on downstream industry customers, exploration of intergovernmental organization partnerships, and greater transparency in product stewardship information. The strategy was approved by the ICCA in October 2005. Work to implement the strategy is currently underway.
CFI Earns National Governance Award The Canada Foundation for Innovation (CFI) has won the prestigious Conference Board of Canada/Spencer Stuart 2006 National Awards in Governance in the Public Sector category. These awards celebrate bold and innovative solutions to governance challenges, and recognize organizations that have broken the mould in the search for governance excellence. “Because of its unique status as a foundation entrusted with public money, the CFI attaches paramount importance to operating in an economical, effective, and transparent manner, and to communicating its activities and results to a wide audience,” said John Evans, chair of the CFI board of directors. “We’ve made great efforts to ensure that our governance practices reflect this fundamental philosophy, and we’re very proud to be recognized for our successes in this regard.” Over the past few years, the CFI board has taken significant steps to increase its interaction with a larger and more diverse community in order to expand its understanding of how Canada can better position itself to continue excelling in an increasingly knowledge-based global economy. Consultation and communication with researchers, private-sector partners, provincial funding agencies, policy-makers, political leaders, and the public have resulted in broader and more strategic thinking by the board, leading to more informed decisions, better program design and delivery, and more robust communications initiatives with its stakeholders. “The CFI has really lived up to its name and has much to be proud of when it comes to governance,” said Anne Golden, president and CEO of The Conference Board of Canada. “By proactively engaging its major stakeholders in its strategic planning, the CFI’s board has taken public sector governance practices to a new level.”

y and large, drugs don’t cure disease. They may lower blood pressure, reduce cholesterol, alleviate pain, restore hormone levels, or help control diabetes, but they don’t solve the underlying problem. Except for antibiotics! If the diagnosis is bacterial infection, the right antibiotic will be curative. At least for now. But the future for these wonder drugs is more murky. Antibiotic resistance is becoming a huge concern. Bacteria, like humans, are biochemically unique. Expose a group of people to the cold virus and they will not all come down with a cold. Obviously, the capacity of the immune system to deal with foreign intruders varies from person to person. Similarly, some bacteria can survive the onslaught of antibiotics and then pass their protective genes on to their progeny. The result is a bacterial population that is resistant to the original antibiotic. Such resistance is an inevitable consequence of the use of antibiotics, and the only protection we have against it is the wise use of these powerful drugs. Unfortunately, we have not always been wise. As pharmaceutical companies successfully developed a wide array of antibiotics, our attitude was that if resistance to one crops up, another will be available to take its place. Until now, this has mostly proven to be so, but the antibiotic cupboard is becoming bare. And there have even been a few chilling reports of resistance to vancomycin, the antibiotic of last resort. Simply stated, the more an antibiotic is used, the less likely that it will maintain its effectiveness. Given that the U.S. Center for Disease Control estimates one third of all antibiotic prescriptions are inappropriate, it is evident that we face a huge problem. Physicians are recognizing this and are becoming less cavalier about prescribing antibiotics. But there is another issue. Although the numbers are somewhat debatable, roughly 25 of the 28 million pounds of antibiotics produced annually in North America are not destined for human use. Instead they are given to hogs, poultry, and cattle, in most cases, not to cure them of disease, but to promote their growth! Since the late 1940s, so-called “sub-therapeutic” doses of antibiotics have been routinely added to animal feed to prevent disease and to increase feed efficiency. Exactly why animals put on weight more readily when
exposed to small doses of antibiotics isn’t clear, but it may have to do with reducing the competition for nutrients by cutting down on the natural bacterial population in the animals’ gut. Some studies also suggest that antibiotic use thins the intestinal wall and increases nutrient absorption. What has become clear, however, is that such sub-therapeutic use of antibiotics leads to the flourishing of antibiotic-resistant bacteria in animals and that such bacteria can infect humans. Chickens, for example, will begin to excrete antibiotic-resistant E. coli in their feces just 36 hours after being given tetracycline-laced feed. Within a short time these bacteria also show up in the feces of farmers. And a truly frightening prospect is that bacteria can pass genes between each other, including the ones that make them resistant to antibiotics. This means that bacteria that have never been exposed to an antibiotic can acquire resistance just by encountering resistant ones. Then consider that animals shed bacteria in their feces and that manure is used as fertilizer, and fertilizer gets into ground water, and it quickly becomes evident how the bacterial resistance problem can mushroom. Thorough cooking kills bacteria, but the widespread incidence of food poisoning demonstrates that poor food handling and undercooking is common. True, most people who come down with bacterial food poisoning just experience some unpleasant cramps and diarrhea and recover without the need for antibiotic treatment. In this case, resistance is not an issue. But there are numerous cases of children, the elderly, or people whose immune systems are compromised, who need antibiotic treatment for food poisoning. And now if the bacteria are resistant to antibiotics, these patients can face a dire situation. Take for example the case of an unfortunate Danish woman who died in 1998 after eating Salmonella-infected pork. She failed to respond to ciprofloxacin (Cipro), the usual antibiotic of choice, because of bacterial resistance. In a piece of elegant research, Danish scientists succeeded in genetically matching the Salmonella-resistant strain to a specific pig farm. Surprisingly, these pigs had not been treated with ciprofloxacin, but the pigs on neighbouring farms had been, and the resistant bacteria had moved between farms!
Antibiotic Resistance
CHEMFUSION Joe Schwarcz, MCIC
In North America, antibiotics known as quinolones have been used since 1995 to treat infections in poultry. While this was great for the chickens’ health, it turned out not to be so good for humans. The most common cause of bacterial gastroenteritis in people is Campylobacter jejuni, and poultry is often responsible. If an antibiotic is needed, ciprofloxacin is the usual choice. But since the introduction of quinolones to farm animals, Campylobacter strains resistant to the drug have emerged. The U.S. Food and Drug Administration has recognized this as such a serious problem that it has made Baytril, a quinolone, the first veterinary drug to be banned because of the emergence of resistant bacteria. While this is the first action of its kind in North America, Europeans have been phasing out antibiotics in animal feed since the 1980s. Sweden banned the use of antibiotics as growth promoters in 1986 and Swedish farmers responded by improving hygiene on farms and by altering feed composition. They showed that meat can be produced for the consumer at virtually the same cost as with antibiotics. And without a cost to consumers’ health! The European Union has followed suit and on January 1, 2006 banned the use of antibiotics as growth promoters in animal feed. Continued on p. 23

New Drug Discovery—Beyond the Bench-Top Daphne C. Ripley, MCIC ew drug discovery does not stop at the laboratory bench. Although basic research may discover thousands of potentially useful medicinal compounds, very few compounds actually make it to market. According to the results of studies published in 2001 by the Tufts Center for the Study of Drug Development, only one in 5,000 compounds identified and tested make it to market, with the average cost to develop a single new prescription drug being US$802 million. A key way of recouping investment in drug development is through the patent system, which gives the patent owner a time-limited monopoly to practise the patented invention—usually 20 years from the date of filing the patent application upon which the patent is granted.
N
examiners for compliance with national patent laws before a patent is granted. Most countries, however, adhere to the same basic patent principles, so it is usually possible to prepare a single patent application suitable for filing around the world. Following the discovery of a new and useful class of chemical compounds, inventors, together with their patent agents, usually prepare a single patent application for filing in one or more countries. Although some amendments can be made to a patent application after it is filed, the scope of permitted amendments may be limited. It is therefore important to try to accurately and correctly describe the invention when the application is being drafted and before it is filed. Inventors play a critical role in meeting this end.
The patent process
Drafting preliminaries
Patents are country specific. It is therefore necessary to apply for a patent separately in each country in which patent protection is sought. Typically, a patent application is examined by qualified
Inventors can facilitate the drafting of an application by providing an invention summary to the patent agent at the outset. The invention summary should provide a basic outline of the invention. In the area

inventors need to ensure that enough information is provided to allow a skilled chemist to make all the compounds covered by the claims of medicinal chemistry, where the invention is one or more new chemical compounds, the summary should describe how the compounds can be made, the structure of the compounds, and possible uses for the compounds. Also, it is often worthwhile to conduct a search of the patent and non-patent literature to understand the state of the art and what the inventors have therefore invented before drafting is commenced.
The invention claimed and described Patent applications and patents have two main parts—the description and the claims. As a general rule, the claims clearly set out what is the invention, fencing off the subject matter sought to be protected by the patent, while the description must provide sufficient information to allow a skilled person to make and use the whole of the invention claimed. Most inventors of new medicinal chemical compounds will only have made a few exemplary compounds at the time the patent application is drafted. Usually these compounds will have a general structure in common, differing only in substituent groups. It is usually possible (and advisable) to claim in a patent application more than the compounds actually made and tested, extrapolating to a larger group of compounds that are expected to work in the same way. Failure to claim more broadly may result in a third party being free to make other, related compounds not specifically claimed, and thereby potentially reducing the value of any resulting patent. Thus, when the application is being drafted, inventors should be asking themselves what other compounds would be expected to work in the same way? For
instance, if an aryl substituent is suitable, would a heteroaryl substituent be suitable? An alkyl group? Etc. In preparing the description, inventors need to ensure that enough information is provided to allow a skilled chemist to make all of the compounds covered by the claims. In some cases this may require a number of examples to show how the compounds were made. In others, where the reactions are standard organic reactions that would be apparent to any skilled chemist, a very few examples may be sufficient. Failure to include sufficient information may be fatal, resulting in a patent not being granted, or it being found invalid after grant. There is also a requirement in most countries that an invention be useful. A patent application must therefore describe at least one use of the invention. In medicinal chemistry, inventors typically have experimental results showing a utility of a representative number of compounds. In many cases, some or all of these results will also be included in the patent application.
Publish and perish— novelty and obviousness In most countries of the world, an invention must be new and non-obvious to be patentable. An invention is generally not considered new if it was in the public domain before the patent application was filed, or if another patent application was earlier filed in the same country and claiming the same invention. An invention is usually considered non-obvious where a skilled person, having regard to what was publicly known before the patent application was filed, would have considered it to be so. Often the prior public disclosure for novelty, and sometimes obviousness, is made by the inventors themselves. If an inventor publishes an academic article or gives a presentation describing the compounds before a patent application is filed, it will not be possible to obtain a patent on those compounds in most countries in the world. Canada and the U.S. are two notable exceptions, with each having a one year grace period in which a patent application can still be filed following such public disclosures by the inventors. So, it is best to defer publishing or presenting research results until after a patent application is filed.
Improvements In most countries, it is possible to patent improvements on a discovery previously publicly disclosed and patented. In medicinal chemistry in particular, improvement patents can be very important. For instance, it is sometimes discovered that a known chemical compound has a new and unexpected utility. It is also often the case in medicinal chemistry (where drugs usually have one or more chiral centres) that a particular stereoisomer, previously unresolved, is found to be particularly useful for treating a disease. Also, it may be discovered that a known compound has a number of polymorphic forms, some or all of which may be useful as medicines. These improvements may all be patentable. So, before publishing results concerning these improvements, talk to a patent agent—you may have another patentable invention. Given the research investment in developing new drugs, take the time to think about patenting and to assist in preparing and reviewing a patent application before it is filed to achieve the most value from your research time and investment.

Orthomolecular Medicine
Abram Hoffer, PhD, MD, FRCP(C) Could medicinal chemistry be applied in an unconventional way to ease the suffering of schizophrenics?
T
here was no successful treatment for schizophrenia in 1950. An admission to any mental hospital in Canada was a life sentence, with no time off for good behaviour. I was director of Psychiatric Research in Saskatchewan, where we had about 2,500 chronic schizophrenic patients in our two large institutions—this was our major problem. In 1960, a physician from the U.S. called me about his 12-year-old son who had been in a psychiatric ward for some time and had just been declared hopelessly ill. He was advised by his son’s psychiatrist to ship him to the closest mental hospital to forget him. By 1960, antipsychotic drugs had already been in use for about five years. The father had just read our first report that vitamin B-3 (nicotinic acid and nicotinamide) in large doses doubled the expected recovery rate. Our conclusion was based upon the first double blind prospective placebo controlled trials in world psychiatry. I advised him to
12 L’ACTUALITÉ CHIMIQUE CANADIENNE AVRIL 2006
give his son niacin. But his son’s psychiatrist refused, claiming that they had already tried it, and that it would fry his brain—both lies. The boy’s father ground the tablets to a powder and while visiting his son daily, fed him sandwiches made of a slice of bread, jam, niacin, jam, and bread. His son loved jam. Twelve weeks later, the child was healthy and wanted to go home. He eventually became a psychiatrist and published a few papers on his research with manicdepressive patients. His son was one of the early patients to recover when treated with orthomolecular methods. Linus Pauling defined “orthomolecular” in his Science paper in 1968. It refers to the use of optimum amounts of nutrients that are normally present in the body. I would add, “and cannot live in its absence.” This is meant to exclude herbs, etc. How had we come from the totally hopeless views in 1950 to seeing a young patient become healthy in 1960? The following is the history of what

happened during that decade that saved a boy from chronic incarceration (or death) in one of the horrible mental hospitals of North America.
How did it start? In the fall of 1951, Humphry Osmond and John Smythies suggested that schizophrenia might be caused by the formation of substances having hallucinogenic properties similar to those induced by mescaline and structurally similar to the catechol amines like adrenalin, noradrenalin, and dopamine. Chemicals that are similar in structure tend to have similar physiological properties. Following this lead, I examined the structure of all the hallucinogens known in 1952. They all contained the indole nucleus or could be indolized in the body. These included LSD, harmine, ibogaine, mescaline, and discoloured pink adrenalin. At the first meeting in 1952 of the Saskatchewan Committee for Schizophrenia Research, Duncan Hutcheon told us that discoloured adrenalin contained the red-pigmented oxidation product adrenochrome. The adrenochrome hypothesis of schizophrenia followed.1 But there were many difficulties with this hypothesis. Stable crystalline adrenochrome had never been synthesized—it had not been shown it could be made in the body from adrenalin, and that it had hallucinogenic properties. However, we discovered how to make crystalline and pure adrenochrome. Eventually, as a result of this basic research, it was found in the body and can be measured in the blood.2, 3 Over the past ten years there has been a major surge of interest 4, 5 in John Smythies’ research on schizophrenia.6, 7, 8, 9 We also needed to know if there was increased oxidation of adrenalin to adrenochrome in the body and brain of schizophrenic patients. Secondly, we had to determine whether it had any hallucinogenic properties. There is no longer any doubt about its psychotomimetic properties, i.e., it causes psychological changes in every animal studied. Schizophrenia patients do suffer from oxidative stress and from a deficiency of antioxidants in the body such as glutathione.10, 11 Finally, and of the greatest importance, was our need for treatment for schizophrenic patients. If we could decrease the formation of adrenochrome, we would have a treatment for schizophrenia.
Vitamin B-3 is a methyl acceptor, and we thought that by giving these patients large amounts of this safe vitamin we might deplete the body’s supply of methyl groups and thus prevent the formation of adrenalin from nordrenalin. And to decrease the oxidation of adrenalin to adrenochrome, we thought that large doses of ascorbic acid, the most effective water soluble antioxidant, would be helpful. Vitamin B-3 is the antipellagra vitamin. Pellagra is characterized by the four Ds—dermatitis, diarrhea, dementia, and death. “Dementia” is not the best term. The proper term is “psychosis” since the pellagrin’s psychosis is indistinguishable from schizophrenia. The reaction to niacin became a diagnostic test. If patients were well within a few days or weeks, they were diagnosed pellagra, and if they did not, they were diagnosed schizophrenia. Niacinamide was added to white flour in 1942 in the U.S. This suddenly stopped that terrible pellagra epidemic that often swept through the southeast U.S. and sometimes made up one third of their admissions to their mental hospitals. One of our first patients given these vitamins was Ken, a 21-year-old catatonic patient at the Saskatchewan Hospital at Weyburn. Ken failed to respond to insulin coma and a series of ECT, which left him worse. By the time we obtained a supply of niacin and vitamin C, Ken was near death in a coma. Osmond and I gave him large amounts of niacin and vitamin C via stomach tube. The next day, he sat up. Thirty days later he was healthy. We continued to treat a few patients until we had seen the effect on eight. They had all recovered or gotten much better. This led to our placebo double-blind prospective randomized controlled therapeutic trials. With our first double blind controlled trial, started in 1952, we treated 30 schizophrenic patients. None of them were the chronic patients in our mental hospitals. We suspected that early cases had a much better chance of responding. They were patients who were sick for the first time or who had been sick, had gotten better, and had relapsed again. They were then followed blind for two years and at the end of that period, the code was broken. We found that one-third of the placebo group was well and that two thirds of the vitamin group was well. Niacin and niacinamide were equally effective.
The chrome indoles— adrenochrome, adrenolutin, and derivatives These coloured indoles form melanin type pigments in the skin and the brain and they are toxic in large doses. The formation of these chrome indoles occurs primarily in two specialized cells—catecholaminergic neurons and melanocytes. They are degenerative and apoptotic agents.12 If present in excess, they will inhibit mitosis or growth and repair and if present in the synapses, will interfere and decrease brain function as do LSD and other hallucinogens.
Effect of oxidative stress— pathological Increased oxidation will increase the formation of adrenochrome and other derivatives of the catecholamines. Anything that increases the rate of these reactions will therefore increase the intensity of the effects of these indoles. These include increased oxygen pressure as in deep sea diving, a deficiency of antioxidants, increased secretion of adrenalin, i.e., stress, and increase in auto catalysis from copper and iron. This is a non-enzymatic pathway used in extreme stress. Too many oxidative catalyses and too few antioxidants are much more apt to be found in diets deficient in protein, essential fatty acids, and essential minerals. A study in Europe showed that the incidence of schizophrenia doubled from 1.7/1,000 to 3.9/1,000 in people born during the last World War, when their mothers were most apt to have suffered severe malnutrition.13 The rate of adult schizophrenia also increased from 0.84 percent risk to 2.40 percent following the famine in China between 1959 and 1961.14 The severe stress induced by the famine probably decreased the efficiency of converting tryptophan into Nicotinamide Adenine Dinucleotide (NAD).
Effect of decreased oxidative stress—therapeutic Any factor that decreases the formation of adrenochrome will be therapeutic. This is done by decreasing the stress of the environment by providing healthy housing, by ensuring adequate nutrition, and by treating the individual with civility (decreasing psychological
APRIL 2006 CANADIAN CHEMICAL NEWS 13
stress). The secretion of adrenalin will then be decreased. It can also be done by inhibiting the oxidation of adrenalin by the use of antioxidants, of which there are many in foods and in the body. Excessive oxidative catalysts, copper and iron, should be decreased if they are elevated, and antioxidants should be used. Anything that will inhibit excessive oxidation15 will be therapeutic. For example glutathione transferase prevents long-lived formation of dopachrome and noradrenochrome.16 The adrenochrome hypothesis using adrenochrome as a member of a class of oxidized derivatives of the catecholamines, explains very economically a good deal of what is known about the schizophrenias.17 It allows for the expression of genetic factors, it accounts for the known relation between anxiety, depression, and stress, and the early symptoms of the disease. It accounts for some of the physical changes found in the patients and for the lower incidence of cancer and the increased incidence of cardiovascular disease and metabolic syndrome. And finally, it accounts for the fact that vitamins in the Krebs cycle and nutrients that have major anti-oxidant properties are therapeutic. The discovery that vitamin B-3 is therapeutic was not serendipitous.18, 19, 20, 21, 22, 23 It arose directly out of the adrenochrome hypothesis. Fewer than 10 percent of schizophrenic patients treated with modern medication alone recover. They do not pay income tax. The metabolic pathology burns forever. Modern psychiatry does not treat schizophrenia successfully. This is the conclusion of almost every published analysis. Malla et al.,24 following a very thorough examination of published studies, conclude “Outcome in regard to functional measure such as employment and community and social adjustment are predicted not only by delay in treatment but also by cognitive dysfunction, residual symptoms, and adherence to medication. Pharmacological and psychological intervention show a promising effect in terms of either delaying or preventing conversion to a syndrome level of ultra high risk individuals, but the evidence is not
yet at a level that can be applied in practice.” Plainly put, Malla and colleagues concluded that although there was some evidence that early intervention might improve some of the treatment results, they presented no data that in fact early onset patients were any better off with treatment. There is no mention of the number that actually became and remained normal. And this is the best prognostic group. This is the group that responds the best to orthomolecular treatment. Jobe et al.25 confirm the poor results. They conclude schizophrenia is a “pooroutcome disorder” and they warn that more attention must be given to suicide and early death. It does not say much for antipsychotic treatment with drugs used alone that after 50 years of research, advertising and use that what they have written is merely a repetition of what has been written over and over for the past half a century. Oxidative stress combined with a deficiency of antioxidants may also play a role in several other chronic neurological diseases including multiple sclerosis, encephalitis, Parkinson’s disease, and amyotrophic lateral sclerosis.
Now, with the medical profession so large and so tightly controlled by its self-governing bodies, it takes much longer. This applies only to new paradigms. It does not apply to old paradigms. Once the concept of antibiotics had been accepted—first described in 1906 or so and popularized during the last great war—new antibiotics can come as fast as the drug companies are willing to make them. In my opinion, orthomolecular psychiatry is such a new paradigm that it must also suffer the same resistance as have other new paradigms including bringing fever down instead of increasing it for smallpox, using cardiac catherization, lumpectomies instead of total mastectomies, and more. I have tried to provide some explanation in my book, Adventures in Psychiatry.27

Why is this treatment still unknown? The best way to answer this question is to quote from what is written on the inside front cover of Stephen R. Brown’s26 book on scurvy. “Scurvy took a terrible toll in the Age of Sail, killing more sailors than were lost in all sea battles combined. The threat of the disease kept ships close to home and doomed those vessels that ventured too far from port. The wilful ignorance of the royal medical elite, who endorsed ludicrous medical theories based on speculative research while ignoring the life-saving properties of citrus fruit, cost tens of thousands of lives and altered the course of many battles at sea.” Almost every technique and method used in modern medicine had to fight its way in the same way. This used to take about 40 years.
are not treated properly. His numerous degrees include a PhD in agricultural biochemistry from the University of Minnesota in 1944. He began in 1950 as director of psychiatric research at the department of public health in Saskatchewan where he and his colleagues developed the adrenochrome hypothesis of schizophrenia which is now, at last, being examined more seriously. They were aided by federal, provincial, and Rockefeller Foundation support, and did the first double blind controlled therapeutic trials in world psychiatry and in North America. Their work led to the modern development of orthomolecular medicine. Hoffer has been in private practice since 1967, first in Saskatoon, SK, and since 1976 in Victoria, BC. He retired recently at age 88 and is now providing information about vitamins. He has published nearly 30 books and “too many papers—nearly 500.”

Mimicking a Good Gene Defect Drug therapy designed to make quitting smoking easier
Y
ou’re a smoker, but your partner isn’t and never has been. Why? And why is it so hard for you to quit when your friend did it without as much trouble? Some of it probably has to do with CYP2A6. When nicotine from a cigarette enters the body, the drug shoots up to your brain and then to your liver. CYP2A6 is an enzyme found in the liver that helps you expel the nicotine from your body, by way of your kidneys. The problem with CYP2A6’s efficiency in metabolizing nicotine so quickly is that once the drug is expelled from your body, you will soon crave more. So you will re-fill your supply with another smoke, then another. The danger, of course, is that after years of feeding the addiction, you have a good probability of suffering debilitating and fatal tobacco-related diseases. But in the late 1990s, a University of Toronto team found that if you have a defective version of CYP2A6, you’re in much better shape for not becoming a smoker—or if you do smoke, you will smoke a lot less. “The defective version of CYP2A6 actually slows down the metabolism of nicotine, so it stays in your body longer,” says Rachel Tyndale, professor of pharmacology, who made the discovery with Edward Sellers, also of pharmacology. “This means that you will have less frequent cravings for nicotine. Or it can result in greater negative effects of nicotine, such as nausea and dizziness, which can turn you off smoking completely.” The presence of CYP2A6 is a fascinating story of adaptation. Tyndale says it is thought that when plants and animals separated early in the evolutionary process, the plants developed toxins to repel animals so that they wouldn’t be eaten. Animals reacted by developing enzymes

that would act as a defence system and allow the body to get rid of the toxins quickly. One of those enzymes is CYP2A6. “It’s a remarkable example of evolution at work. But this enzyme actually increases smoking, while its defective variation decreases the need to smoke. And not everyone has the defect. So we’re trying to imitate the defect to help people quit smoking more easily.” Tyndale, Sellers, and colleagues Ewa Hoffmann, Sharon Miksys, Yushu Rao, and Helma Nolte have been pursuing a method of mimicking the action of the genetic defect and producing a drug therapy that would either replace or be used in conjunction with current nicotine replacement methods, such as the nicotine patch. “A lot of methods don’t work as well as they could because they are one-size-fits-all approaches. Every smoker has different nicotine needs, so quitting will be much easier if the therapy can be customized. Our drug therapy will allow a smoker to adjust intake of nicotine to when they need it at different times during the day.” Tyndale and Sellers are carrying out their research with support from the Canada Research Chairs, the Canadian Institutes of Health Research and the Centre for Addiction and Mental Health. They have also formed a company, Nicogen, to develop the drug therapy. Their patents are currently issuing. Tyndale points out that approximately 35 percent of smokers make a serious attempt to quit each year, but only 5 percent are successful. “Quitting smoking is a tough battle. But we believe our process will give people a much better chance of staying off tobacco for good.”

Throwing the Wrench with Perfect Aim Annick Gauthier has a passion for disease biochemistry.
A
s a child growing up in the small town of Pincourt, QC, Annick Gauthier knew two forces would guide her life— she was fascinated by how the body works, particularly diseases, and she wanted to help people. At first she thought she’d be a pathologist. No, she realized later, that’s too late in the disease process. She wanted to prevent disease. To understand the first deadly kiss between pathogen and human cell in such intimate detail that she could throw a wrench into the molecular works. “I’m interested in understanding what’s happening at the most basic biochemical level. If we can figure out how, for example, the Hepatitis C virus actually uses the body to reproduce itself, then we can set up roadblocks that stop the culprit from acting,” says Gauthier, winner of the 2005 NSERC Howard Alper Postdoctoral Prize. In the late 1990s, Gauthier’s passion for disease biochemistry led her to PhD research in the lab of University of British Columbia microbiologist Brett Finlay, a world leader in the study of the interaction between bacteria and their human “host” cells. She arrived at an exciting time. Finlay’s lab group had just made a major discovery about enteropathogenic E. coli, a major cause of infantile diarrhea that kills an estimated 100,000 children a year worldwide. Surprisingly, unlike most bacteria, enteropathogenic E. coli uses its own protein to attach to a host cell. It’s like installing a door and having the key. Gauthier set her sights on determining how the bacterium inserts this protein. Through six years of research, she determined that a group of bacterial proteins called the type III system act as a superhighway to deliver the bacterial attachment protein into the human cell in a single step. The finding is exciting in that the type III system only exists in pathogenic bacteria, and thus might be an ideal target for vaccines or antibiotics.
16 L’ACTUALITÉ CHIMIQUE CANADIENNE AVRIL 2006
For her present post-doctoral work, Gauthier decided to switch her focus to tackle an even more difficult scourge—the Hepatitis C virus. “I want to use what I learned from bacteria and apply it to virology. I think that this brings a fresh perspective to the problem,” she says from New York where’s she’s working in the virology lab of Charles Rice, an internationally acclaimed researcher at The Rockefeller University. “Often people think about viruses as inert substances, but I think there’s a real interplay going on between the virus and the host.” Approximately three percent of the world population, a staggering 170 million people (including many Canadians) are infected with the Hepatitis C virus. It’s a chronic infection that often leads to cirrhosis or liver cancer. There’s presently no vaccine or even effective therapy for the disease. Gauthier’s post-doctoral research, now in its second year, is focused on understanding how a remarkably simple virus—a strand of RNA that encodes only 10 proteins—hijacks our liver’s cellular machinery while staying hidden from our immune defences. Using her experience with E. coli, she has focused on a particular protein, dubbed NS4B. She suspects it might be the trigger for the creation of a web-like structure that develops in infected liver cells. And since she has already determined that the virus can’t replicate when NS4B is experimentally deleted, the protein could also be the ideal target for future therapies. Says Gauthier, “My hypothesis is that NS4B interacts with host cell proteins to create this membranous web and that’s the site for viral replication. So I want to figure out how it’s doing it.”

The Economic Impact of a Flu Pandemic H5N1 concerns hold wide-ranging implications—and a surprising number of opportunities.
I
t is impossible these days to open a newspaper or magazine without seeing a story about the arrival of avian flu in a new country, or reports of additional outbreaks in chickens or another human death due to the organism. As the current strain of avian flu inevitably makes its way across the world, the warnings of a looming pandemic become louder—as does the need for proper planning to deal with the effects of such an event. The uncertainties surrounding the timing of the pandemic and the potential disruptions that would ensue will have a profound effect on world financial markets and their support infrastructure. Already, the avian flu has cost the Asian economies in excess of $15 billion and resulted in the deaths and culling of 150 million birds. This cost will only grow and in the event of a pandemic, will escalate exponentially. Recently, a senior World Bank economist told a gathering of world leaders that the world’s gross domestic product (GDP) would drop by at least two percent. This would amount to about US$800 billion over the course of the year. These figures have been extrapolated from the consequences of the SARS epidemic of 2003, which caused a two percent drop in GDP in East Asian economies. The turmoil in the global markets would inevitably impact things closer to home. For some businesses, the current situation creates additional risks that need to be factored in, whereas for others there will be opportunities. The following sets out some basic facts about the potential crisis and its impact on the economy in this part of the world.
Influenza—the link to avian flu All influenza viruses originate in aquatic birds in the wild, where the virus infects their digestive systems. Along the route of migratory flyways, due to erosion of natural habitats, domestic birds frequently come in contact with migrating birds and the virus has access to domestic fowl. Subsequently, the virus can mutate and adapt to infecting mammals such as pigs raised in proximity to fowl and ultimately humans

who come in contact with these animals. In the event of a major change in the virus, which results in the emergence of a new strain not previously seen by the human population, the resulting massive global proliferation of infection is defined as a pandemic.
Pandemic influenza— history and potential of H5N1 There have been three documented influenza pandemics in the last 100 years—1968 to 1969, 1957 to 1958, and the most devastating, the “Spanish flu,” from 1918 to 1919. There is evidence that in all three pandemics, the causative viruses arose in birds. The current avian influenza virus making news, the H5N1 strain, arose first in 1997 in Hong Kong (in chicken flocks), where it infected about 18 people and killed six. There are several reasons for thinking that this virus may actually be the precursor to a pandemic strain. H5N1 has never been found circulating in general human populations before. Consequently, it is expected to be particularly problematic if it acquires efficient human-to-human transmission while maintaining its virulence. It has mutated into a more lethal form over time. Since early 2004, it has become 100 percent lethal in domestic chickens and has also acquired the capability of infecting other species such as rodents and pigs. The observed mortality rate in humans reported to have been infected (mainly through contact with infected birds) appears to be quite high—the virus has killed more than 60 people in Asia so far.
Response—public policy Sixty percent of Western countries have some plan on paper at least. Part of this is acquiring stockpiles of vaccine and anti-viral drugs to administer to selected members of their population, should the need arise. There are also ongoing debates on the role and respect of intellectual property (patents) on “essential” drugs and technologies, especially for
The vaccine industry will be foremost in the pandemic preparedness plan developing countries with limited resources. The following factors, among many others, will require honest and deep analysis—the ethical debates of making drugs and vaccines available to people in front-line countries, domestic policies on how these will be rationed and distributed, including which age groups will get priority, and how order will be maintained.
Impact—financial markets and businesses As we all know, financial markets hate uncertainties and this threat of a looming pandemic will soon start to take its toll in a more meaningful way. The flu season in the Northern Hemisphere runs from November to April. The chance of an epidemic increases during this period along with the risk to the markets. Economists have begun to look at the vulnerability and potential meltdown of the financial markets in the event of a flu pandemic. This would be mainly as a consequence of panic, breakdown of order, shortages, and severe restrictions on free flow of goods and services. Some sectors that may be particularly affected are tourism, travel, lodging and hospitality, airlines, and transportation. We can expect commodity prices to fall significantly due to chaos in world markets, as well as housing and real estate to also be adversely affected. Businesses in the food supply chain are also at risk—there is already evidence in Europe that sellers of chickens have seen their share prices plummet (e.g. LDC of France has seen share prices decline by 16 percent since October 7, 2005), whereas fish producers like Pescanova of Spain have gained on speculation. Adverse effects would also be seen here in companies such as Tyson foods and fast food restaurants like KFC (Yum Yum Brands Inc.). Businesses that depend on just-in-time inventory (such as the auto industry) could be hit hard with a double whammy—lack of delivery of inventory and staff shortages. Central banks worldwide would be under tremendous pressure to pump liquidity into the markets and
consequently, we can expect a sharp decline in interest rates. The best way for businesses to mitigate the impact on their operations is to study the risk to their particular circumstance and plan accordingly. Individuals can also plan appropriately and a significant mitigating factor may be planning to reduce overall indebtedness.
Opportunity—life science and pharmaceutical companies As always, there are also opportunities for some businesses, especially those in the life sciences area and delivery of services. The increased funding available for developing new technologies, vaccines, surveillance, testing, and drugs will drive growth in specific groups of businesses. The vaccine industry will be foremost in the pandemic preparedness plan. Influenza vaccines are theoretically the best way to prevent the virus from spreading indiscriminately. The established influenza vaccine producing companies, such as Sanofi Pasteur, Chiron, GSK, CSL (Australia), and Solvay (Netherlands) should certainly benefit from government contracts for stockpiles (Sanofi Pasteur and Chiron have already been awarded multimillion dollar contracts for the vaccine in the U.S.). Other new vaccine companies, such as Crucell (Netherlands) and Protein Sciences Corp. (U.S.) will also be able to easily access developmental funds for better production technology including cell-culture processes, improvements in the lag time for manufactured vaccine turnaround and new ways of administering vaccines (such as patch technologies being developed by Iomai Corp. in the U.S.), which may allow less vaccine to be used per person. Manufacturers of animal fluvaccines, such as Intervet (Netherlands), would also be net beneficiaries in terms of growth. Companies that currently market antiviral drugs that have been shown to inhibit the H5N1 virus (such as Roche with Tamiflu and GSK with Relenza) will certainly see an enhancement to their top-line revenues as countries stock up on these drugs. In the short-term these could be net beneficiaries in terms of market value. Longer term, however, it is harder to estimate since the outcome of the debates on compulsory licensing may have an impact. Other companies developing new generations of anti-viral drugs or technologies,
especially those shown to be active against the new strains of avian influenza (e.g. BioCryst and Gilead in the U.S. and Biota in Australia), will be another set of businesses that certainly have potential for doing well. The situation here is similar to the anti-HIV therapeutic area, in that several types of drugs may be required to counter drug resistance that may arise. Similarly, just as in the areas of bio-terrorism, SARS, and mad cow disease, diagnostic companies generating sensitive, convenient, and rapid tests (such as Response Biomedical of Vancouver, BC) that can be used to screen humans, as well as domestic flocks, will be growth industries. Technology companies that develop products that would allow better surveillance and modeling of a potential pandemic, both in terms of hardware, databases, and software, are part of another sector that would benefit.
No room for complacency Whether the current threat of bird flu will ultimately turn into a catastrophic pandemic cannot be confirmed definitely at present. However, at the very least, this is a wakeup call. Complacency in this matter is not an option. Both financial institutions and businesses will need to plan and factor in potential disruptions due to events such as a pandemic flu. Players in the market will need to factor the risk of a pandemic flu into their current portfolios—both from a sectored and individual company basis. There is opportunity in the market as well, and reasonable hedging strategies may mitigate some of the risk.

W H E R E L I G H T A N D M AT T E R M E E T Have you considered the seemingly endless applications of photochemistry? 20 L’ACTUALITÉ CHIMIQUE CANADIENNE AVRIL 2006
Marius Ivan, MCIC
P
hotochemistry as a chemical process has pretty much been around since the first photons were emitted in the universe, light triggered chemical reactions being the source of life on Earth. A systematic study of photochemical reactions started at the dawn of the 19th century and the beginning of the 20th century. The Italian chemist, Giacomo Ciamician, and the German chemist, Paul Stilber, were among the first to study photochemical reactions at the end of the 19th century using sealed flasks exposed to sunlight.1 Ciamician presented a big part of his work during a talk he gave in 1908 where he mentioned photochemical reactions that form the basis of photochemistry—oxidations and reductions, fragmentations, auto-oxidations, polymerizations, condensations, and rearrangements. Photochemistry established itself long ago as one of the strongest fields of physical chemistry. It has evolved into a multidisciplinary science lying at the crossroads of medicine, physics, biology, physical, organic, inorganic and theoretical chemistry, polymer, and materials science. Photochemistry, as science, is concerned with the interaction between light and matter, and the photoproducts obtained either directly or from other chemical reactions induced by the initially excited molecule. The best way to describe the behaviour of a molecule upon absorption of a quanta (photon) of light is by using a Jablonski diagram, shown in figure 1. Upon absorption of a photon by a chromophore, an electron is promoted from the singlet ground state (S0) to an intermediate vibrational level of the excited singlet state (S1). In terms of Frontier Orbital Molecular Theory, this transition can be viewed as promoting the electron from the HOMO to the LUMO, which in the case of organic chromophores, could be a π–π* or an n-π* transition (these two are the most often encountered transitions, but σ–σ* are also possible for saturated chromophores exposed to very energetic photons). Following vibrational relaxation (VR) to the lowest vibrational level of S1, the molecule can either relax to the ground state by releasing heat to the environment through a process called internal conversion (IC) or by emitting light (fluorescence), or undergo intersystem crossing (ISC) to the triplet state. Although ISC is a “forbidden” process, it still occurs, favoured by spin-orbit coupling. From its T1
state the molecule can either relax to S0 by emitting light (phosphorescence), react with itself (intramolecular process), or with other molecules (intermolecular process) and form photoproducts. The excited state is very short lived at room temperature, usually between 10 e(-15) to 10 e(-6) s for a singlet state and 10 e(-6) to 30 s for triplet state.2 An excited molecule can decay through internal conversion releasing heat (a radiationless process), by emitting light (fluorescence or phosphorescence), by abstracting a hydrogen intra- or intermolecularly, through isomerization, rearrangement, electron transfer, energy transfer, or by breaking one or more bonds. Most intermediates are radicals, radical ions, or ions.
Figure 1 Although the space is limited, an attempt to bring forward some of the most frequently encountered and important applications of photochemistry will be made in the following. Many photochemical reactions occur in biological media, the most famous being photosynthesis. Photochemical reactions occur in skin exposed to sunlight and synthesis of many compounds, such as vitamin D, is triggered by light. At the same time, exposure to sunlight could induce unwanted photochemical reactions in the skin. Prolonged exposure to sun induces sunburn, which in turn may be prevented by applying sunscreens. The role of the sunscreen is to protect the skin from the “damaging” UVA and UVB radiation by absorbing this radiation and releasing the energy as heat, doing photophysics rather than photochemistry. The interest and the resources allocated for research in this field in academia and in industry are considerable, one source for skin cancer being the photochemical
. . . in the future, science will pay tribute to the photon and photonics reactions that occur upon exposure to sunlight. Free radicals, produced in the body upon interaction of different chemical agents with light, cause DNA and cell damage. Exposure to sun is related to various types of cancer, aging, and cataracts. To counterbalance these negative effects, researchers have looked for compounds that will capture these free radicals, namely antioxidants. Free radicals are produced either by direct photolysis or by photosensitization, a process during which molecules in excited states transfer their energy to other molecules in ground state. Triplet oxygen is a good energy acceptor and it can be excited to its singlet state by energy transfer from a photosensitizer. Superoxide is a reactive species which can induce DNA damage and in the end mutagenesis. Photodynamic therapy (PDT) is a technique successfully used for cancer treatment, especially skin cancer, but other types as well. As a recognition of the importance of this topic, ACCN published an entire issue dedicated to PDT in 2002. The principle is simple and makes use of selective photosensitization. The patient is injected with a dye, usually 48 hours before exposure. The dye selectively associates with the cancerous cells indicating exactly where the affected tissues are located. The tissues are irradiated with a wavelength at which the dye absorbs, usually in the infrared region of the spectrum. Excited dye molecules act as sensitizers, producing singlet oxygen, which will further damage the DNA of the affected cells, stopping them from replicating. Research in this field is concerned with dyes absorbing in infrared and near infrared regions, since these wavelengths penetrate deeper in the body and are not harmful. However, compounds absorbing at shorter wavelengths are used as well, in a technique involving absorption of two photons from IR laser sources. A photosensitizer used in PDT must have certain properties. It should not be toxic for the organism in its ground state, should be able to selectively associate with the cancerous tissue, absorb preferably in the IR region, and have an excited state lifetime long enough to allow energy transfer.

Fluorescent sensors are used in many fields. In analytical chemistry, fluorescence spectroscopy is a versatile and sensitive technique, able to determine impurities at very low concentrations, as low as 10 e(-7) M. Selective binding of certain compounds, such as metal ions or organic molecules to these dyes, alters their fluorescence by either shifting the emission maximum or by changing the emission intensity. Since fluorescence is affected by many factors, fluorescent probes are used in different media to detect changes in the surrounding environment such as polarity, morphology, temperature, pressure, etc. In fact, designing and developing fluorescent probes for various applications is one of the most important fields of photochemistry. The increasing need for energy and the limited availability of classic resources has fueled research for alternative sources of energy. Solar energy is a renewable, clean, and readily available form of energy that can be transformed into electrical energy by solar cells through photochemical conversion of light into electricity. Research in this field has been going on for more than 50 years, starting with inorganic silicon-based solar cells developed by Bell Laboratories and continuing today with organic, hybrid, and polymer-based solar cells. Relatively recently developed polymeric and hybrid solar cells have shown promising conversions of light into current, and appear to be the ideal choice for future applications due to their lightweight, flexible shape, and the ease to integrate them into products such as clothing, cars, and roofs, etc.3 Photosensitive materials with exciting properties are developed and reported every day. Photochromism is an interesting and intriguing property of materials. Compounds that reversibly change their color upon irradiation (either by bond breaking and bond forming or by isomerization) have found application in electronics and in everyday life. Photochemical properties are altered by the medium surrounding the chromophore, and these observations have led to the development of a new direction, namely supramolecular photochemistry. Compounds encapsulated in zeolites or clays behave differently than in solution, and photochemistry at interfaces or on surfaces is another interesting application. Nanoparticles show intriguing properties, and in particular they have very interesting

photochemical properties, with absorption and emission of these particles depending on their size and shape. Carbon, metal, semiconductor, and polymer nanoparticles have found applications in areas previously dominated by organic or organometallic dyes. An example is the application of nanoparticles as photosensitizers in PDT.4 Designing a molecule to be used in photochemistry, developing it until the desired behaviour is reached, is a long process. A key is to monitor the excited states and the reactive intermediate species formed upon absorption of a photon. These short-lived intermediates are observed using laser flash photolysis,5 a technique that allows observation of species living as low as a few femtoseconds and helps determine reactions’ rate constants. Working at low temperatures or in glass may prolong the lifetime of these intermediates, thus allowing characterization using other techniques. Once in an excited state, different reaction pathways could be induced by different substituents for example, or by choosing a different solvent (hydrogen donor, polar or non-polar, more or less viscous, etc). The presence of oxygen influences the outcome of a photochemical reaction, oxygen being a very good radical and triplet state quencher. Pollutants in the atmosphere and in marine water are subjected to photochemical reactions. Reactive species, such as hydroxyl radicals, are obtained in troposphere following light triggered decomposition of some gaseous pollutants. One of the most extensive applications is the use of photochemistry as a tool in organic synthesis. Many reactions that require strong energetic conditions (catalysts, high temperature, and pressure, etc.) may be done by exposing the reagents to light of a suitable wavelength, thus lowering the cost and reaction time. Light-initiated reactions are a green alternative to the classic thermal synthesis. Pericyclic reactions are one of the classic examples taught in photochemistry courses, but all the chromophores show specific reactions that could be exploited for synthetic purposes.6 Many other interesting applications of photochemistry have not been mentioned in this article. One application with implications in our everyday lives is photolithography—a technology used to manufacture computer chips found in
almost all the electronic devices, from cell phones to calculators, cars, laptops, DVD, and MP3 players. The importance of photochemistry as a science is reflected in the number of groups and laboratories around the world that do research in this field. In almost every Canadian university, there is at least one group doing research in this field and many more whose projects involve photochemistry. Advances in laser and imaging technologies allow new and exciting applications of photochemistry. If the 20th century was dominated by the electron and electronics, it looks that in the future, science will pay tribute to the photon and photonics.

NRCan Regulation of EC Proposed Explosive Precursors Regulatory Provisions for the Export and Import of NonHazardous Waste Natural Resources Canada Explosive Regulatory Division (NRCanERD) is developing new regulations to address security concerns related to access to “restricted components” (i.e., explosive precursor chemicals), which currently include: • ammonium nitrate • sodium nitrate • potassium nitrate • nitric acid (68+ percent) • hydrogen peroxide (30+ percent) • sodium chlorate • potassium chlorate • potassium perchlorate • nitromethane A task group was formed with all the Canadian sodium chlorate producers to work with NRCan-ERD to develop a sodium chlorate security code of practice to deal with security issues related to sodium chlorate. The Sodium Chlorate Task Group (SCTG) is being coordinated through the Alliance for Environmental Technology (AET). The security code of practice includes most of the security elements from the CCPA and ACC’s Responsible Care™ Codes of Practices and is a description of what the Canadian chemical industry is already doing or should be doing. The code focuses on limited access to the product during the manufacturing, transportation, and distribution processes. The regulations will be less prescriptive and will incorporate the use of “guidelines” where developed (i.e., the regulations may refer to the code of practice for what is required). The SCTG last met with the ERD in December 2005 and with changes in the federal government, the publication of the draft regulations will be delayed until mid-2006, with possible im plementation before the end of 2006. To date, security codes of practice have been developed by industry task groups for two of the substances on the list: ammonium nitrate (by the Canadian Fertilizer Institute) and sodium chlorate (by SCTG). ERD indicated that they will develop general requirements for the substances that do not have security codes of practice developed. All companies that produce, transport, or distribute the explosive precursors will have to register with the ERD, and this will be spelled out in the new regulations.
Environment Canada will be drafting proposed regulatory provisions for the export and import of non-hazardous waste. The provisions are intended to protect Canada’s environment and the health of Canadians from potential risks posed by the transboundary movement of non-hazardous waste and to ensure that this waste is handled in an environmentally sound manner. Exports, imports, and transits of non-hazardous waste destined for recycling or recovery operations are not targeted. Environment Canada (EC) has prepared an on-line discussion document that contains an abridged description of the objectives, structure, and content of the proposed regulatory provisions, as well as the operational procedures to be followed once they are put into place. To view the discussion document, visit www.ec.gc.ca/CEPARegistry/ documents/regs/non_haz_wast/cover.cfm. Environment Canada invites all stakeholders to provide their comments on the proposed regulatory provisions until May 1, 2006. The next opportunity for stakeholders to comment on the proposed regulatory provisions will be following the publication of the provisions in the Canada Gazette, Part I anticipated in 2007–2008.

In Memoriam The CIC extends its condolences to the families of: William A. (Bill) Ayer, FCIC, FRCS, passed away in his sleep on December 2, 2005, at the University of Alberta Hospital. He was born in Middle Sackville, NB, on July 1, 1932 and obtained his BSc and PhD degrees from the University of New Brunswick. After a year at Harvard with R. B. Woodward, Ayer began his academic career at the University of Alberta in 1958 where he built an interWilliam A. (Bill) Ayer, FCIC nationally recognized natural products group. He became the authority on lycopodium alkaloids, some of which are being considered to be of value in the treatment of Alzheimer’s disease. He identified the alkaloid defence substances of the lady bug, metabolites of the fairy ring mushrooms, and a number of diterpenoids with unique structural features from bird’s nest fungi. Metabolites of blue stem fungi that infect lodge pole pine and aspen were first identified by Ayer. He went on to study metabolites from fungi that are responsible for a number of other diseases—canker formation in plants, for black root disease in pine, for Dutch elm disease, and from fungi that inhibit Dutch elm disease. He discovered phytoalexins, compounds produced by plants upon infection that resist the infecting organism, in his studies of black spot disease on canola and coffee trees. Ayer’s work initiated a new field of research that is steadily expanding and is important to agriculture and forestry. His accomplishments were recognized by the receipt of the Merck Sharp Dohme and the John Labatt Awards from the CIC and the E. W. R. Steacie Award of the CSC. In 1992, he was made University Professor, the University of Alberta’s highest honour. Despite such praise, Ayer remained modest and unassuming. He mentored about 70 graduate students, post-doctoral fellows and research associates, authored 210 publications, and received several patents. His students were well trained and many have made significant contributions in their own careers. He was an enthusiastic and popular lecturer at both the undergraduate and graduate levels. Ayer was editor of the Canadian Journal of Chemistry from 1977 to 1983, editor-in-chief from 1984 to 1988, and president of the Canadian Society for Chemistry from 1988 to 1989. University of Alberta
Duncan Lunam Glenn, MCIC, was born in Bristol, QC, April 5, 1930, and grew up on a farm alongside the Ottawa River. He was educated at Shawville High School and McGill University, where he received an athletic scholarship and was on both the hockey and the football teams. He graduated with a BSc specializing in agricultural chemistry in 1953 and microbiology in 1955. Glenn loved his work in sales, travelling from Nova Scotia to British Columbia, as a chemical mining specialist. He worked in the Québec iron ore industry and for several chemical companies, including CIL, DuPont, and Monsanto. After moving to Toronto, ON, in 1956, he worked at BASF for 15 years in the production of plastics, chemicals, and vitamins. He was also employed at National Silicates. He was a member of the CIC from 1957 until his death, and he and his wife, Joan Ashworth-Glenn, MCIC, were often to be seen at Toronto Section meetings. He was also a member of a variety of other professional associations including the Professional Sales Association, Chartered Chemists, the Metallurgical Institute of the American Chemical Society, the Toronto Paint Society, and the Explosives Engineers Society.

E. Roland Menzel, inventor of laser fingerprint technology and Horn professor of physics at Texas Tech University (TTU), passed away due to an illness. He was 62. Menzel was best known for creating laser fingerprint technology in the mid- to late-1970s while a member of the scientific staff for Xerox Research Centre of Canada in Toronto, ON. While working on colour copier technology, Menzel discovered how fingerprints react to lasers. His laser fingerprint discovery was labelled one of the “Milestones of Canadian Chemistry in the 20th Century” by The Chemical Institute of Canada. Lynn Hatfield, chair of TTU’s department of physics, said he has lost a beloved friend and an important member of his faculty. “He was a very colourful character,” Hatfield said. “And, he was an outstanding researcher. He gave very good and interesting talks about his work. During his time at Xerox, he realized you could see fingerprints by shining a laser on them. The laser light excites fingerprint material and causes it to give off light.” Following that discovery, Menzel moved to Texas Tech University in 1979. He created The Center for Forensic Studies at TTU in 1982 with the aim of promoting innovation in physical evidence examination. The centre’s mission is to research new methods of evidence examination, hold workshops for law enforcement personnel to expose them to new technologies and conduct case examinations for law enforcement agencies. In 2003, the centre expanded to include an interdisciplinary forensic science minor program. As well as giving workshops to the Federal Bureau of Investigation and the Secret Service, Menzel travelled to China, Israel, Guam, and Saudi Arabia to teach law enforcement officials how to use emerging technology to fight crime.

Winners for 2006 Garry Hanan, MCIC, received his BSc from the University of Winnipeg in 1989 and worked under the supervision of Steve Loeb on ditopic receptors for metal ions. After a year as an exchange student at Auckland University, New Zealand, he returned to work with Steve Loeb, FCIC, at the University of Windsor on Pt complexes of sulfur-containing macrocycles. Hanan then moved to the Université Louis Pasteur Garry Hanan, MCIC in Strasbourg, France and completed his PhD in supramolecular chemistry under the supervision of Jean-Marie Lehn in 1995. After a post-doctoral appointment as an Alexander Von Humboldt Fellow with Manfred T. Reetz in Mülheim, Germany, he worked with Vincenzo Balzani (Bologna) and Sebastiano Campagna (Messina) as an NSERC post-doctoral fellow. Hanan joined the department of chemistry at the University of Waterloo in 1998 and moved to the Université de Montréal (U de M) in 2002, where he is currently an associate professor. He will use his CNC/IUPAC travel award to attend the 37th International Conference of Coordination Chemistry in Cape Town, South Africa in August 2006.
26 L’ACTUALITÉ CHIMIQUE CANADIENNE AVRIL 2006
Le Comité national canadien de l’Union internationale de chimie pure et appliquée (CNC/UICPA) remet des bourses de voyage aux jeunes scientifiques canadiens depuis 1982. Ces bourses sont subventionées par le Fonds Gendron (administré par la Société canadienne de chimie) et par les compagnies associées au CNC/UICPA (Boehringer Ingelheim (Canada) Inc., Merck Frosst Canada Inc. et Bruker Biospin Ltd.). L’objectif de ces bourses est de venir en aide aux jeunes scientifiques et ingénieurs canadiens, qui sont à moins de 10 ans de l’obtention de leur doctorat, afin de leur permettre de présenter leurs travaux lors d’une conférence commanditée par l’UICPA à l’extérieur du Canada et des ÉtatsUnis. Date limite pour postuler : le 14 octobre 2006. Renseignements supplémentaires : www.cnc-iupac.org.
Hanan’s research program at U de M encompasses several aspects of metallosupramolecular chemistry, including synthetic heterocyclic and coordination chemistry. Metallo-organic complexes with novel photophysical properties are assembled with the ultimate goal of producing artificial photosynthetic devices. Matthew Moffitt, MCIC, obtained his PhD at McGill University under the supervision of Adi Eisenberg, FCIC, and was an NSERC post-doctoral fellow in the group of Mitchell Winnik, FCIC, at the University of Toronto. He is currently an assistant professor in the department of chemistry at the University of Victoria. His research in physical polymer chemistry and materials science targets the application of spontaMatthew Moffitt, MCIC neous structure-forming processes in polymer systems (e.g. phase separation, dewetting, micellization) for the self-assembly of hierarchical polymer/inorganic nanocomposites. His interest in the self-assembly of hybrid building blocks of polymers and inorganic nanoparticles (quantum dots, metal nanoparticles) is fueled by the potential for bottom-up design of new nonlinear optical materials, photonic bandgap crystals, and light-emitting elements
CSC BULLETIN SCC
for photonic circuits. With the support of a CNC/IUPAC Travel Award, Moffitt will attend the World Polymer Congress–Macro 2006, the 41st International Symposium on Macromolecules in Rio de Janeiro, Brazil in July 2006. Moffitt’s research in physical polymer chemistry and materials science investigates the application of spontaneous structure-forming processes in polymer systems (e.g. phase separation, dewetting, micellization) for the controllable self-assembly of hierarchical polymer/ inorganic nanoparticle composites. Specific targets include bottom-up design of new nonlinear optical materials, photonic bandgap crystals, and light-emitting elements for photonic circuits. Enzyme modification is a promising field, with many industries rapidly increasing their activities in this sector. Joelle Pelletier, MCIC’s goal is to develop a deeper understanding of enzyme structure-function relationships, thereby providing better tools to modify enzymes for synthetic purposes. Much of her research effort is devoted to the area of ligand selectivity. To this end, she and her team apply Joelle Pelletier, MCIC combinatorial mutagenesis to the active site of enzymes, combined with kinetic and biophysical characterization and molecular modelling, as a general approach to enzyme modification. The First International IUPAC Conference on Green-Sustainable Chemistry, to be held in Dresden (September 10 to 15, 2006) is the first IUPAC Series Conference dedicated to green chemistry. It deals with all aspects of environmentally benign and sustainable chemistry, including “Benign Synthesis Routes” such as industrially relevant enzymatic catalysis. Pelletier’s multidisciplinary bioorganic chemistry research program aims to develop a deeper understanding of enzyme structure-function relationships. She applies combinatorial mutagenesis to the active site of enzymes as a general approach for the improvement or development of industrially-relevant enzymes.
Born in Nottingham, England, Alison Thompson, MCIC, obtained her BSc from the University of Leicester in 1993. In 1996, she was awarded her PhD from the University of Sheffield for research on the development of catalytic asymmetric aziridination and epoxidation reactions with Varinder Aggarwal. She then moved to Strasbourg, France and worked with Arlette Solladié Cavallo for a year as a Alison Thompson, MCIC post-doctoral fellow with a Royal Society/NATO award. In 1997, she joined The University of British Columbia to work with David Dolphin, FCIC, on the investigation of self-assembly processes involving pyrrolic molecules, first as a postdoctoral fellow and than as a research assistant. In 2001, she moved to Halifax, NS, to take up a faculty position at Dalhousie University with an NSERC University Faculty Award. Her current research interests include the synthesis and applications of dipyrromethene complexes, the development of new methodology for the efficient synthesis of functionalized pyrroles, and the design and synthesis of prodigiosins for the evaluation against breast cancer. With grateful receipt of a CNC/IUPAC Travel Award for 2006, Thompson will attend the 16th International Conference on Organic Synthesis (ICOS 16), June 11 to 15, 2006 in Merida, Mexico. At ICOS 16, Thompson will present work on novel diastereoselective complexation reactions that generate dipyrromethene helicates with >99 percent selectivity, as well as novel methodology by which to prepare functionalized pyrroles. The latter project includes the use of new sulfur-based protecting groups and the application of studies that involve microwave technology. The awards are sponsored jointly by CNC/IUPAC’s company associates and the Gendron Fund. Visit www.cnc-iupac.org/awards06_e.html for further information.

CSCT BULLETIN SCTC
Report of the President Canadian Society for Chemical Technology
T
he CSCT ended 2005 on a high note, with increased membership and a healthy financial surplus. Membership at the end of 2005 showed more full-fee memberships than the previous year.
Governance and finances The CSCT is on a more sound financial footing than a few years ago, largely due to the professional development courses that have been offered. Although figures were not audited at the time of writing, it appears that the CSCT will have a surplus of $8,400. The future of the CSCT had been considered, with the CSCT Board looking at the possibility of forming a chemical technology division of the CIC in place of the present society. The CIC Board passed a motion to incorporate the CSCT in 2006, rather than make the format change. This will bring the CSCT in line with the other two societies within the CIC. The CIC and society By-law revision project has begun. The CSCT has a major challenge to attract new members, reflecting the overlap of recognized disciplines such as biotechnology and the environment with the pure chemical technology or chemical engineering technology disciplines. The present By-laws restrict expansion to some extent with the narrow definition of CSCT membership requirements. Changes in the membership should bring about many new exciting changes within the CSCT.
Tom Sutton, FCIC
Professional development The CSCT has once again hosted two professional development courses—ICPES and Lab Safety in conjunction with the CSC and CSChE conferences. The Lab Safety Course was held four times in 2005, twice at Bruce Power in Tiverton, ON, with 60 attendees, at Mosaic in Esterhazy, SK, and during the CSChE Toronto Conference. This course will also be offered in Halifax, NS, at the CSC conference in May 2006.
cCT Applications for the certified chemical technology (cCT) designation have increased immensely over the past year from one or two a year to over 15 for 2005. In particular, there has been an increase in nonCanadian educated chemical technologists. Assessing the education and work information provided for these individuals has proven to be a challenge. A subcommittee was set up to look into handling these assessments. New requirements for additional information have been put into place to process the present applications. The updated CSCT By-laws should clarify some issues on assessment of work and educational requirements.
CTAB The CSCT Board plays an active role in CTAB. I have been involved in meetings over the past two months involving revisions to the requirements for accrediting chemical technology programs.
Student symposia Two successful student symposia took place in 2005, the Student Symposium at SIAST in Saskatoon, SK, in March and the Career Symposium held in conjunction with the CSChE conference in October in Toronto, ON. Both were well attended with approximately 40 attendees at each.
Final words I would like to take this opportunity to thank my fellow CSCT Board members: Brian Kohler, MCIC, Murray Watt, MCIC, Cathy Cardy, MCIC, Joffre Berry, MCIC, Kevin Ferris, MCIC, Amin Hirji, MCIC, and Ovie Ekewenu, MCIC, for their support and assistance during my term as president. I would also like to thank Roland Andersson, MCIC, and all of the staff of the CIC National Office, whom I have worked with in my various capacities while on this Board. I welcome Joffre Berry to his new role as CSCT president and his new Board of directors and look forward to seeing this society move forward in this changing world under their direction. In conclusion, I would like to remind all CSCT members that the CSCT and The Chemical Institute of Canada belong to you. Get involved! Tom Sutton, FCIC CSCT President, 2004–2006
