Description
A dual inhibitor of MEK1 (IC50 = 160 nM) and Raf kinases (IC50s = 56, 19, and 8.2 nM for C-RAF, B-RAF, and B-RAFV600E, respectively); selective for these kinases over a panel of 254 additional kinases at 10 µM; decreases MEK and ERK phosphorylation in a panel of seven cancer cell lines expressing mutant K-RasG13D, K-RasQ61K, K-RasG12D, H-RasG12D, or B-RAFV600E at 1 µM; inhibits proliferation of SK-MEL-28, SK-MEL-2, MIA PaCa-2, SW480, and HCT116 cancer cells (IC50s = 28-227 nM) but not A549, HCT15, or PC3 cancer cells (IC50s = >1,000 nM for all); reduces tumor growth in an HCT116 mouse xenograft model at 25 mg/kg four times per day
