FGTI-2734 mesylate is a RAS C-terminal mimetic dual farnesyl transferase (FT) and geranylgeranyl transferase-1 (GGT) inhibitor with IC 50 s of 250 nM and 520 nM for FT and GGT, respectively. FGTI-2734 mesylate can prevent membrane localization of KRAS, hence solving KRAS resistance problem and thwarting mutant KRAS patient-derived pancreatic tumors In Vitro FGTI-2734 mesylate (1-30 μM; 72 hours) induces apoptosis in mutant KRAS-dependent, but not mutant KRAS- independent, human cancer cells. FGTI-2734 mesylate (3-30 μM; 72 hours) inhibits both protein prenylation of HDJ2, RAP1A, KRAS and NRAS. FGTI-2734 inhibits KRAS membrane localization in RAS-transformed murine NIH3T3 cells and in mutant KRAS human cancer cells. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Apoptosis AnalysisCell Line: MiaPaCa2, L3.6pl, Calu6 cells Concentration: 1, 3, 10, 30 μM Incubation Time: 72 hours Result: Induced apoptosis in mutant KRAS-dependent human cancer cell lines Western Blot AnalysisCell Line: KRAS, HRAS, and NRAS-transformed NIH3T3 cells Concentration: 3, 10, 30 μM Incubation Time: 72 hours Result: Inhibited both protein prenylation of HDJ2, RAP1A, KRAS and NRAS. In Vivo FGTI-2734 mesylate (intraperitoneally; 100 mg/kg/day for 18 to 25 days) only inhibits tumor growth in mutant KRAS-dependent tumors but not in mutant KRAS-independent tumors . MCE has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model: Male SCID-bg mice following injection of MiaPaCa2, L3.6pl, Calu6, A549, H460 and DLD1 cancer cells Dosage: 100 mg/kg Administration: Intraperitoneally; daily; for 18 to 25 days Result: Inhibited tumor growth in mutant KRAS-dependent tumors. Form:Solid IC50& Target:IC50: 250 nM (FT) and 520 nM (GGT)
