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.

Biological target: FTI-2148 is a RAS C-terminal mimetic dual farnesyl transferase (FT-1) and geranylgeranyl transferase-1 (GGT-1) inhibitor with IC50s of 1.4 nM and 1.7 μM, respectively.
In vitro activity: To determine the potency and selectivity of FTI-2148, its ability to inhibit the transfer of farnesyl from [3H]FPP and [3H]GGPP to HRas CVLS and H-Ras CVLL, respectively, was evaluated. Table 1 shows IC50s of the inhibitors. FTI-2148 (IC50, 1.4 nm) is 2.5 times more potent than GGTI-297 (IC50, 55 nm). Table 1 also shows that FTI-2148 (1200-fold) is highly selective for FTase over GGTase. hus, for FTIs, replacement of reduced cysteine by the imidazole derivative and the phenyl substituent by tolyl (Fig. 1) resulted in much higher selectivity with little loss of potency. Although FTI-2148 alone was capable of inhibiting human tumor growth, drug removal resulted in tumor regrowth. Reference: Cancer Res. 1999 Oct 1;59(19):4919-26. https://cancerres.aacrjournals.org/content/59/19/4919.long
In vivo activity: To evaluate the effects of replacing the reduced cysteine by an imidazole derivative and the phenyl group by a tolyl, the antitumor potency of FTI-2148 and FTI-276 (both i.p. and s.c. delivery) were compared in the human lung adenocarcinoma A-549 cell nude mouse model. Fig. 5 A ⇓ shows that, over a period of 83 days, tumors from animals that were treated with vehicle reached an average size of 839.56 ± 162.66 mm3, whereas those treated with FTI-276 or FTI-2148 grew to average sizes of 193.21 ± 61.88 mm3 or 122.95 ± 17.36 mm3, respectively. Thus, FTI-276 and FTI-2148 inhibited A-549 tumor growth by 82 and 91%, respectively. This suggested that the effect of FTI-276 and FTI-2148 on A-549 tumor growth in nude mice is cytostatic. To confirm this, A-549 cellbearing nude mice were treated with FTI-276 or FTI-2148 (25 mpk/day for 14 days) and followed tumor growth for an additional 15 days after drug cessation. Fig. 5B ⇓ shows that FTI-276 and FTI-2148 delivered via s.c. mini-pumps at a rate of 25 mpk/day for 14 days inhibited tumor growth by 50 and 77%, respectively, by the end of the 2-week treatment. Furthermore, after drug treatment was stopped, the tumors from the FTI-276 group grew faster than those from the FTI-2148 group. Thus, the data show that FTI-2148 is more effective than FTI-276.
