Datasheet of LB-100
Description:. LB-100 is a small-molecular protein phosphatase 2A(PP2A)inhibitor with IC50 of 0.85 μM and 3.87 μM in BxPc-3 and Panc-1 cells. in vitro: By using CCK-8 assays, LB-100 showed dose-dependent inhibition of cell growth in both cell lines. The IC50 of LB-100 was 0.85 μM and 3.87 μM in BxPc-3 and Panc-1, respectively. While the IC50 of doxorubicin was 2.3 μM and 1.7 μM in BxPc-3 and Panc-1, respectively, LB-100 did not synergize with doxorubicin in both cell lines. LB-100 treatment reduced PP2A activity by 30–50% in different pancreatic cell lines. LB-100 treatment increased the relative concentration of doxorubicin by up to 2.5 fold compared to cells not exposed to LB-100. LB-100 significantly enhanced inhibition of HCC by doxorubicin and cisplatin in vitro and in vivo in a PP2A-dependent way, while having little inhibitory activity when used alone. in vivo: LB-100 injection resulted in rapid blood flow at the surface of tumors in mice. LB-100 promoted vascular endothelial growth factor secretion and vasculogenic mimicry, associated with increased microvessel density and blood perfusion of tumor cell xenografts. LB-100 also enhanced paracellular endothelial permeability to Evans Blue dye and doxorubicin in vivo and in vitro, presumably by altering vascular endothelial-cadherin contact between cells.
