h-CHK1 complexed with A431994
Overview
We describe a series of potent and selective oxindole-pyridine-based, protein kinase B/Akt inhibitors. The most potent compound 11n in this, series demonstrated an IC(50) of 0.17nM against Akt1 and more than, 100-fold selectivity over other Akt isozymes. The selectivity against, other protein kinases was highly dependent on the C-3 substitutions at the, oxindole scaffold, with unsubstituted 9e or 3-furan-2-ylmethylene (11n), more selective and 3-(1H-pyrrol-2-yl)methylene (11f) or, 3-(1H-imidazol-2-yl)methylene (11k) less selective. In a mouse xenograft, model, 9d, 11f, and 11n inhibited tumor growth but with accompanying, toxicity.
