New inhibitor of 3-phosphoinositide dependent protein kinase-1 identified from virtual screening

Bioorg Med Chem Lett. 2012 Feb 15;22(4):1629-32. doi: 10.1016/j.bmcl.2011.12.121. Epub 2012 Jan 4.

Abstract

3-Phosphoinositide-dependent protein kinase-1 (PDK1) has been recognized as a promising anticancer target. Thus, it is interesting to identify new inhibitors of PDK1 for anticancer drug discovery. Through a combined use of virtual screening and wet experimental activity assays, we have identified a new PDK1 inhibitor with IC(50)=~200 nM. The anticancer activities of this compound have been confirmed by the anticancer activity assays using 60 cancer cell lines. The obtained new PDK1 inhibitor and its PDK1-inhibitor binding mode should be valuable in future de novo design of novel, more potent and selective PDK1 inhibitors for future development of anticancer therapeutics.
