Discovery of 5-pyrrolopyridinyl-2-thiophenecarboxamides as potent AKT kinase inhibitors

A pyrrolopyridinyl thiophene carboxamide 7 was discovered as a tractable starting point for a lead optimization effort in an AKT kinase inhibition program. SAR studies aided by a co-crystal structure of 7 in AKT2 led to the identification of AKT inhibitors with subnanomolar potency. Representative compounds showed antiproliferative activity as well as inhibition of phosphorylation of the downstream target GSK3β.
