Itk kinase inhibitors: initial efforts to improve the metabolical stability and the cell activity of the benzimidazole lead

Bioorg Med Chem Lett. 2008 Oct 15;18(20):5537-40. doi: 10.1016/j.bmcl.2008.09.017. Epub 2008 Sep 7.

Abstract

Previously, we reported a series of novel benzimidazole based Itk inhibitors that exhibited excellent enzymatic potency and selectivity but low microsomal stability. Employing a structure based approach a new series of inhibitors with comparable potency and selectivity to the original series and with a potential for improved microsome stability was identified.
