描述 | BAY 1125976 is a potent and selective allosteric AKT1/2 inhibitor with IC50 values of 5.2nM and 18nM for full-length AKT1 and AKT2, respectively, and exhibits much less potency against AKT3. BAY 1125976 effectively inhibited the basal levels of AKT phosphorylation at both sites, T308 and S473 with IC50 values of 0.9 and 1.1 nM, respectively, accompanied with blocking phosphorylation of a downstream signaling molecule 4EBP1 by phosphorylation at mTOR substrate T70 with an IC50 of 35 nM, in KPL-4 cells. BAY 1125976 inhibited cell proliferation in a broad panel of human cancer cell lines with IC50 values ranging in 0.02-10μM, particularly with high activity against breast and prostate cancer cell lines expressing estrogen or androgen receptors. Administration of BAY 1125976, p.o., exhibited strong in vivo efficacy in both cell line and patient-derived xenograft models such as the KPL4 breast cancer model carrying PIK3CAH1074R mutant, the MCF7 and HBCx-2 breast cancer models and the AKTE17K mutant driven prostate cancer (LAPC-4) and anal cancer (AXF 984) models at doses ranging in 10-50mg/kg. | ||
作用机制 | BAY 1125976 binds into an allosteric binding pocket formed by kinase and PH domain.[1] |
