Benzimidazole- and benzoxazole-based inhibitors of Rho kinase

Bioorg Med Chem Lett. 2008 Dec 15;18(24):6390-3. doi: 10.1016/j.bmcl.2008.10.095. Epub 2008 Oct 25.

Abstract

Inhibitors of Rho kinase have been developed based on two distinct scaffolds, benzimidazoles, and benzoxazoles. SAR studies and efforts to optimize the initial lead compounds are described. Novel selective inhibitors of ROCK-II with excellent potency in both enzyme and cell-based assays were obtained. These inhibitors possess good microsomal stability, low cytochrome P-450 inhibitions and good oral bioavailability.
