Bioorg Med Chem Lett. 2009 May 15;19(10):2735-8. doi: 10.1016/j.bmcl.2009.03.129. Epub 2009 Mar 28.

Abstract

B-Raf kinase plays a critical role in the Raf-MEK-ERK signaling pathway and inhibitors of B-Raf could be used in the treatment of melanomas, colorectal cancer, and other Ras related human cancers. We have identified novel small molecule pyrazolo[1,5-a]pyrimidine derivatives as B-Raf kinase inhibitors. Structure-activity relationship was generated for various regions of the scaffold to improve the biochemical profile.
