SERP Comments:

This compound is a potent and selective inhibitor of 3-phosphoinositide-dependent protein kinase 1 (PDK1). It has low nanomolar potency against the PDK1 enzyme. GSK2334470 appears selective based on the published data. It has been tested against 95 different protein kinases, and none of them were inhibited to a significant extent at a 1 uM screening concentration. In addition, GSK2334470 does not inhibit the 15 lipid kinases that were tested. In cells, GSK2334470 is active at concentrations between 30 nM and 1 uM, depending on the particular conditions and readout being measured. The authors demonstrate, for example, inhibition of the phosphorylation of SGK1, SGK2, SGK3, P70S6K, and AKT in cells in certain contexts. No pharmacokinetic data was reported, so suitability for in vivo experiments is unknown.
