FTI 277 HCl FTase inhibitor

Cat.No.S7465

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. This compound inhibits cell growth and induces apoptosis. This chemical is effective in clearing HDV viremia.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC50/Ki
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. 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. [1] It causes increased apoptosis after irradiation and increases radiosensitivity in H-ras-transformed rat embryo cells. [2] This chemical also inhibits cell growth and induces apoptosis in drug-resistant myeloma tumor cells. [3] 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. [4]

Kinase Assay
FTase and GGTase I Activity 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. [5]
