Bioorg Med Chem Lett. 2011 Aug 1;21(15):4436-40. doi: 10.1016/j.bmcl.2011.06.021. Epub 2011 Jun 16.

Abstract

A potent series of inhibitors against the B-Raf(V600E) kinase have been developed that show excellent activity in cellular assays and good oral bioavailability in rats. The key structural features of the series are an arylsulfonamide headgroup, a thiazole core, and a fluorine ortho to the sulfonamide nitrogen.
