FTase-IN-1 (compound 17a) is a highly effective inhibitor of fanesyl transferase (FTase), exhibiting a remarkable IC50 value of 0.35 μM. This compound demonstrates significant cytotoxicity potential and exhibits powerful antitumor activity [1].
Methyl ganoderate A, an inhibitor of Farnesyl protein transferase (FPT) with an IC50 of 38 µM, exhibits potential anticancer effects. Additionally, it inhibits fatty acid amide hydrolase (FAAH), further underscoring its therapeutic potential.
FGTI-2734 mesylate, a RAS C-terminal mimetic compound with dual farnesyltransferase (FT) and geranylgeranyl transferase-1 (GGT) inhibitory activities (IC50s of 250 nM and 520 nM for FT and GGT, respectively), mitigates KRAS resistance by preventing its membrane localization, effectively impeding mutant KRAS patient-derived pancreatic tumors.
XR3054 is a novel inhibitor of farnesyl protein transferase (FPTase). XR3054 inhibited the proliferation of the prostatic cancer cell lines LnCAP and PC3 and the colon carcinoma SW480 and HT1080 (IC50 values of 12.4, 12.2, 21.4 and 8.8 microM, respectively) but was relatively inactive when tested against a panel of breast carcinoma cell lines. The activity did not relate to the presence of mutant or wild-type ras in the cell lines tested. In conclusion XR3054 inhibits ras farnesylation, MAP kinase activation and anchorage-independent growth in NIH 3T3 transformed with v12 H-ras. Since the antiproliferative effect of the compound is not related to the ras phenotype, XR3054 may also have effects on other cell signaling mechanisms.
FTI-2148 is an inhibitor of RAS C-terminal mimetic dual farnesyltransferase (FT-1) and geranylgeranyl transferase-1 (GGT-1) (IC50s: 1.4 nM and 1.7 μM, respectively).
FTI-2148 diTFA is a RAS C-terminal mimetic dual farnesyltransferase (FT-1) and geranylgeranyl transferase-1 (GGT-1) inhibitor with IC50s of 1.4 nM and 1.7 μM, respectively.
α-hydroxy Farnesyl phosphonic acid is a nonhydrolyzable analog of farnesyl pyrophosphate which acts as a competitive inhibitor of farnesyltransferase (FTase). At concentrations greater than 1 μM, α-hydroxy farnesyl phosphonic acid inhibits the processing of Ras in Ha-ras-transformed NIH3T3 cells.
Lipiferolide is an inhibitor of farnesyl protein transferase(FPTase), it inhibits the FPTase activity in a dose-dependent manner, and shows cell growth inhibitory activity against several tumor cells, it possesses cytotoxic activity against KB cells. Liriodenine also has antiplasmodial activity.
