Discovery of cell-active phenyl-imidazole Pin1 inhibitors by structure-guided fragment evolution

Bioorg Med Chem Lett. 2010 Nov 15;20(22):6483-8. doi: 10.1016/j.bmcl.2010.09.063. Epub 2010 Sep 17.

Abstract

Pin1 is an emerging oncology target strongly implicated in Ras and ErbB2-mediated tumourigenesis. Pin1 isomerizes bonds linking phospho-serine/threonine moieties to proline enabling it to play a key role in proline-directed kinase signalling. Here we report a novel series of Pin1 inhibitors based on a phenyl imidazole acid core that contains sub-μM inhibitors. Compounds have been identified that block prostate cancer cell growth under conditions where Pin1 is essential.
