General description

A cell-permeable triarylimidazole compound that acts as a reversible, ATP-competitive, and highly potent inhibitor of Raf kinase (IC50 = 10 nM & Kd = 2.4 nM for B-raf) with 7-, 30-, and 70-fold selectivity over p38α, GSK-3β, and Lck, respectively. Cellular data have indicated that the compound is more effective towards Raf-1and A-Raf than B-Raf.
