B-Raf inhibitor 1 is an inhibitor of B-Raf kinase with IC50 values of 0.31μM and 0.72μM for cell proliferation, respectively in A375 and HCT116 [1].

B-Raf is important in signal transduction and some mutant B-Raf occurs in cancer cells. The most common mutation of these is V600E, which makes B-Raf kinase constitutively active. B-Raf inhibitor 1 belongs to the type IIA inhibitors and binds to the DFG-out ATP-binding site of B-Raf. The selectivity of B-Raf inhibitor 1 is less than of other type inhibitors. Besides mutant B-Raf, it can also inhibit wild type B-Raf and other tyrosine kinase. In cells with wild type B-Raf, B-Raf inhibitor 1 can activate the RAF-MEK-ERK signaling pathway via Raf dimerization. The preclinical toxicity test shows B-Raf inhibitor 1 can induce hyperplasia in a mouse model [1, 2].
