FGTI-2734 is a RAS C-terminal mimetic dual farnesyl transferase (FT) and geranylgeranyl transferase-1 (GGT) inhibitor with IC50s of 250 nM and 520 nM for FT and GGT, respectively. FGTI-2734 can prevent membrane localization of KRAS, hence solving KRAS resistance problem and thwarting mutant KRAS patient-derived pancreatic tumors[1]. IC50: 250 nM (FT) and 520 nM (GGT)[1]
FGTI-2734 (1-30 μM; 72 hours) induces CASPASE-3 and PARP cleavage in MiaPaCa2, L3.6pl and Calu6 cells[1]. FGTI-2734 (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[1]. Apoptosis Analysis[1] Cell Line: MiaPaCa2, L3.6pl and Calu6 cells
FGTI-2734 (intraperitoneally; 100 mg/kg/daily for 18 to 25 days) only inhibits tumor growth in mutant KRAS-dependent tumors but not in mutant KRAS-independent tumors[1]. Animal Model: Male SCID-bg mice following injection of MiaPaCa2, L3.6pl, Calu6, A549, H460 and DLD1 cancer cells[1]

Dual Farnesyl and Geranylgeranyl Transferase Inhibitor Thwarts Mutant KRAS-Driven Patient-Derived Pancreatic Tumors
Clin Cancer Res 2019 Oct 1;25(19):5984-5996.PMID:31227505DOI:PMC6774803
Purpose: Mutant KRAS is a major driver of pancreatic oncogenesis and therapy resistance, yet KRAS inhibitors are lacking in the clinic. KRAS requires farnesylation for membrane localization and cancer-causing activity prompting the development of farnesyltransferase inhibitors (FTIs) as anticancer agents. However, KRAS becomes geranylgeranylated and active when cancer cells are treated with FTIs. To overcome this geranylgeranylation-dependent resistance to FTIs, we designed FGTI-2734, a RAS C-terminal mimetic dual FT and geranylgeranyltransferase-1 inhibitor (GGTI). Experimental design: Immunofluorescence, cellular fractionation, and gel shift assays were used to assess RAS membrane association, Western blotting to evaluate FGTI-2734 effects on signaling, and mouse models to demonstrate its antitumor activity. Results: FGTI-2734, but not the selective FTI-2148 and GGTI-2418, inhibited membrane localization of KRAS in pancreatic, lung, and colon human cancer cells. FGTI-2734 induced apoptosis and inhibited the growth in mice of mutant KRAS-dependent but not mutant KRAS-independent human tumors. Importantly, FGTI-2734 inhibited the growth of xenografts derived from four patients with pancreatic cancer with mutant KRAS (2 G12D and 2 G12V) tumors. FGTI-2734 was also highly effective at inhibiting, in three-dimensional cocultures with resistance promoting pancreatic stellate cells, the viability of primary and metastatic mutant KRAS tumor cells derived from eight patients with pancreatic cancer. Finally, FGTI-2734 suppressed oncogenic pathways mediated by AKT, mTOR, and cMYC while upregulating p53 and inducing apoptosis in patient-derived xenografts in vivo. Conclusions: The development of this novel dual FGTI overcomes a major hurdle in KRAS resistance, thwarting growth of patient-derived mutant KRAS-driven xenografts from patients with pancreatic cancer, and as such it warrants further preclinical and clinical studies.
