Datasheet of E6005
Description:. "SF2535 is a selective and potent delta isoform PI3K inhibitor with a similar profile to GS-1101 (CAL101). Additionally, SF2535 also inhibits bromodomain proteins becoming the first-in-class dual inhibitor of its kind.In Vitro: SF2523 treatment decreases protein levels of MYCN and Cyclin D1, the MYCN target, and inhibits AKT activation by blocking phosphorylation of AKT at Ser473. SF2523 treatment leads to the displacement of BRD4 from both MYCN promoter sites. SF2523 interacts robustly with the full-length BRD4 (Kd=140 nM) and exhibits comparable affinity to the BRD4 first BD (BD1) (Kd=150 nM), however it binds more weakly to the second BD (BD2) of BRD4 (Kd=710 nM). Comparison of binding affinities of SF2523 for BDs of other proteins reveal that it binds equally well to BDs of BRD4, BRD2, and BRD3; shows moderate binding to BDs of CECR2 and BRDT; but associates much weaker with other BDs. In Vivo: SF2523 treatment results in a significant reduction of tumor volume compared with control. Importantly, SF2523 shows no gross toxicity to the treated mice, as there is no notable change in body weight. Tumors from SF2523-treated mice have markedly reduced MYCN, pAKT, and Cyclin D1 levels compared with levels of these proteins in vehicle-treated mice tumors." E6005 potently and selectively inhibited human PDE4 activity with an IC50 of 2.8 nM and suppressed the production of various cytokines from human lymphocytes and monocytes with IC50 values ranging from 0.49 to 3.1 nM. In mice models, the topical application of E6005 produced an immediate antipruritic effect as well as an anti-inflammatory effect with reduced expression of cytokines/adhesion molecules. On the basis of these observed effects, topical E6005 ameliorated the appearance of atopic dermatitis-like skin lesions in two types of AD models, hapten- and mite-elicited models, exhibiting inhibitory effects comparable to that of tacrolimus. The use of 14Clabeled E6005 showed rapid clearance from the blood and low distribution to the brain, contributing to the low emetic potential of this compound. E6005 is a novel therapeutic agent with antipruritic activity for the treatment of AD.
