Phosphoinositide-dependent protein kinase-1 (PDK1) is a master regulator of the AGC family of kinases and an integral component of the PI3K/AKT/mTOR pathway. As this pathway is among the most commonly deregulated across all cancers, a selective inhibitor of PDKI might have utility as an anticancer agent. Herein we describe our lead optimization of compound 1 toward highly potent and selective PDKI inhibitors via a structure-based design strategy. The most potent and selective inhibitors demonstrated submicromolar activity as measured by inhibition of phosphorylation of PDK1 substrates as well as antiproliferative activity against a subset of AML cell lines. In addition, reduction of phosphorylation of PDK1 substrates was demonstrated in vivo in mice bearing OC1-AML2 xenografts. These observations demonstrate the utility of these molecules as tools to further delineate the biology of PDKI and the potential pharmacological uses of a PDK1 inhibitor.
