Biological Activity

Description FTI 277 HCl is a potent and selective farnesyltransferase (FTase) inhibitor with IC50 of 500 pM, about 100-fold selectivity over the closely related GGTase I. FTI 277 HCl inhibits cell growth and induces apoptosis. FTI 277 HCl is effective in clearing HDV viremia.
Targets
FTase [1]
(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. FTI-277 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. [1] FTI-277 causes increased apoptosis after irradiation and increases radiosensitivity in H-ras-transformed rat embryo cells. [2] FTI-277 also inhibits cell growth and induces apoptosis in drug-resistant myeloma tumor cells. [3] In SH-SY5Y cells, FTI-277 diminishes the toxic effects of methamphetamine on induction in cell degeneration, activation in c-Jun-N-terminal kinase cascades, and Ras activation. [4]
In vivo

In mice coinfected with hepatitis B virus (HBV) and HDV, FTI-277 (50 mg/kg/d i.p.) effectively clears HDV viremia. [5]

Protocol (from reference)

Kinase Assay:

[1]
  • FTase and GGTase I Activity Assay

    FTase 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.
Cell Assay:

[3]
  • Cell lines

    8226, U266, and H929 multiple myeloma cell lines

  • Concentrations

    ~10 μM

  • Incubation Time

    96 hours

  • Method

    Cells are seeded at 8000–14 000 cells/well in 96-well plates. To establish a dose–response to FTI-277, cells are incubated for 96 h in two-fold serial dilutions ranging from 3.75 times 10-7 M to 1 times 10-5 M. Following continuous drug exposure, 50 μL MTT dye is added. The insoluble formazan complex is solubilized with DMSO and absorbance measured at 540 nm. IC50s and 95% confidence intervals are calculated by regression analysis of the linear portion of the dose–response curve.
Animal Study:

[5]
  • Animal Models

    HBV/HDV-transgenic FVB mice

  • Dosages

    50 mg/kg/d

  • Administration

    i.p.
