BMS 214662 is a potent inhibitor of farnesyltransferase (FTase; IC50 = 1.3 nM).1 It is selective for FTase over geranylgeranyl transferase (GGTase; IC50 = 1,900 nM). It inhibits the growth of MEK2, A2780, and PC3 cancer cells expressing wild-type Ras (IC50s = 2.5, 0.04, and 0.15 μM, respectively), as well as HCT116, MIP, RC-165, and MIA PaCa-2 cells expressing mutant K-Ras (IC50s = 0.06, 0.3, 0.3, and 0.12 μM, respectively). BMS 214662 induces apoptosis in HCT116 cells in a concentration-dependent manner. In vivo, BMS 214662 (600 mg/kg) is curative in an HCT116 mouse xenograft model. It also reduces tumor growth in Calu-1, HT-29, EJ-1, and MIA PaCa-2 mouse xenograft models.WARNING This product is not for human or veterinary use.
