FTI-277 is a highly potent and selective FTase inhibitor. At concentration as low as 10 nM, FTI-277 inhibits H-Ras processing and the processing is blocked by more than 95% at 3 μM. 
Ras proteins are plasma membrane-associated GTPases. It acts as relay switches transducing biological information from extracellular signals to the nucleus. Farnesyltransferase (FTase) is an enzyme that catalyzed the Ras farnesylation, a lipid posttranslational modification that is required for Ras-induced malignant transformation. 
FTI-277, the methyl ester derivative of FTI-276, is extremely potent (ICGraphic = 100 nM) at inhibiting H-Ras, but not the geranylgeranylated Rap1A processing in whole cells. FTI-277 is a farnesylation-specific inhibitor which inhibits the processing of both oncogenic and normal Ras. 
In mice that hydrodynamically transfected to produce Hepatitis delta virus (HDV) viremia, FTI-277 treatment is effective in inhibiting viremia.
