GSK690693GSK690693 is a pan-Akt inhibitor targeting Akt1/2/3 with IC50 of 2 nM/13 nM/9 nM in cell-free assays, also sensitive to the AGC kinase family: PKA, PrkX and PKC isozymes. GSK690693 also potently inhibits AMPK and DAPK3 from the CAMK family with IC50 of 50 nM and 81 nM, respectively. GSK690693 affects Unc-51-like autophagy activating kinase 1 (ULK1) activity, robustly inhibits STING-dependent IRF3 activation. Phase 1. |
UPN cells were treated with GSK690693 or MK2206 (1 uM) for 1h followed by LPA (10 uM), EGF or IGF-1 (10 ng/ml) for another 1h and Western blot was performed. Band intensities of phospho-AKT (p-AKTS473), phospho-S6 (p-S6S240/S244), phospho-YB-1 (p-YB-1S102) and YB-1 were quantified and normalized to the intensity of ERK2. It directly determined the role of AKT using two potent, AKT inhibitors with distinct actions—a catalytic domain inhibitor, GSK690693, and an allosteric inhibitor, MK2206 -in UPN and SKOV3 cells, which showed appreciable AKT and YB-1 phosphorylation upon growth factor stimulation. GSK690693 increased basal and growth factor-induced AKT phosphorylation due to blocking a negative feedback loop downstream of AKT, whereas MK2206 abolished both basal and growth-factor-induced AKT phosphorylation. |
