Biochem/physiol Actions

GSK2126458 (GSK458) is an orally active, highly potent and selective ATP site inhibitor against phosphoinositide 3-kinase (PI3K p110α CI50 = 40 pM; p100 α/δ/γ/β Ki = 19/24/60/130 pM; p110α E542K/E545K/H1047R Ki = 8/8/9 pM), mTOR (mTORC1/C2 Ki = 180/300 pM) and DNA-PK (IC50 = 280 pM) with >10,000-fold selectivity over more than 240 other kinases evaluated. GSK458 inhibits cellular AKT pS473 and growth of breast cancer cells in cultures (pAKT/growth IC50 = 0.41/3 nM/T-47D and 0.18/2.4/BT-474) and in vivo (0.3-3 mg/kg, 5x per wk for 3 wks p.o. in mice).
