Successful shape-based virtual screening: the discovery of a potent inhibitor of the type I TGFbeta receptor kinase (TbetaRI)

Bioorg Med Chem Lett. 2003 Dec 15;13(24):4355-9. doi: 10.1016/j.bmcl.2003.09.028.

Abstract

We describe the discovery, using shape-based virtual screening, of a potent, ATP site-directed inhibitor of the TbetaRI kinase, an important and novel drug target for fibrosis and cancer. The first detailed report of a TbetaRI kinase small molecule co-complex confirms the predicted binding interactions of our small molecule inhibitor, which stabilizes the inactive kinase conformation. Our results validate shape-based screening as a powerful tool to discover useful leads against a new drug target.
