Mechanism of Action

Targets/IC₅₀/Ki	FTase (Cell-free assay) 500 pM
In vitro	FTI-277 inhibits Ras processing with an IC50 of 100 nM, but not the geranylgeranylated Rap1A processing in whole cells. This compound induces accumulation of cytoplasmic non-farnesylated H-Ras, accumulates inactive Ras/Raf complexes in the cytoplasm, and blocks constitutive MAPK activation in H-RasF cells. It causes increased apoptosis after irradiation and increases radiosensitivity in H-ras-transformed rat embryo cells. This chemical also inhibits cell growth and induces apoptosis in drug-resistant myeloma tumor cells. In SH-SY5Y cells, this agent diminishes the toxic effects of methamphetamine on induction in cell degeneration, activation in c-Jun-N-terminal kinase cascades, and Ras activation.
Kinase Assay	FTase and GGTase I Activity Assay
Kinase Assay	FTI 277 HCl (FTI-277) and GGTase I activities from 60,000×g supernatants of human Burkitt lymphoma (Daudi) cells are assayed. Inhibition studies are performed by determining the ability of Ras CAAX peptidomimetics to inhibit the transfer of [³H]farnesyl and [³H]geranylgeranyl from [³H]farnesylpyrophosphate and [³H]geranylgeranylpyrophosphate to H-Ras-CVLS and H-Ras-CVLL, respectively.
In vivo	In mice coinfected with hepatitis B virus (HBV) and HDV, FTI-277 HCl (50 mg/kg/d i.p.) effectively clears HDV viremia.
