An orally bioavailable inhibitor of the serine/threonine protein kinase AKT (protein kinase B) isoforms 1 and 2 (AKT1/2) with potential antineoplastic activity. AKT1/2 inhibitor BAY1125976 selectively binds to and inhibits the phosphorylation and activity of AKT1/2 in a non-ATP competitive manner, which may result in the inhibition of the phosphatidylinositol 3 (PI3K)/AKT/mammalian target of rapamycin (mTOR) signaling pathway. This may lead to both the reduction of cell proliferation and the induction of cell apoptosis in AKT-overexpressing tumor cells. The AKT signaling pathway is often deregulated in cancer and is associated with tumor cell proliferation, survival and migration. Check for active clinical trials using this agent. (NCI Thesaurus)
