MedKoo CAT#: 406425

CAS#: 251577-09-0 (free base)

Description: FTI-2148 is a potent farnesyltransferase inhibitor with potential antitumor activity. FTI-2148 is highly selective for FTase (IC50, 1.4 nM) over GGTase I (IC50, 1700 nM). FTI-2148 suppressed the growth of the human lung adenocarcinoma A-549 cells in nude mice by 33, 67, and 91% in a dose-dependent manner. Combination therapy of FTI-2148 with either cisplatin, gemcitabine, or Taxol resulted in a greater antitumor efficacy than monotherapy.
