GSK690693GSK690693 是一种泛Akt抑制剂，靶向作用于Akt1/2/3，在无细胞试验中IC50为2 nM/13 nM/9 nM，也对AGC激酶家族:PKA，PrkX和PKC同工酶敏感。GSK690693 也能有效地抑制CAMK家族的 AMPK 和 DAPK3，对应的IC50值分别为50 nM和81 nM。GSK690693 可影响 Unc-51-like autophagy activating kinase 1 (ULK1) 的活性并有效地抑制 STING-dependent IRF3 的激活。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.
