  • HCV replicon genotype 1b cells were passaged in the presence of G418 alone (medium 694 control) or G418 with miravirsen, SPC4729 (oligonucleotide negative control) or telaprevir for 28 days in fixed concentrations at a multiple (X) of the EC50 of miravirsen or telaprevir. Colony formation was assessed by staining surviving cells with crystal violet.

    Cleavage of DDB1 by NS3/4A is inhibited by the NS3/4A inhibitor VX-950. The 293 cells were transfected with N-terminal or C-terminal Flag-tagged DDB1 (N-Flag-DDB1 or DDB1-C-Flag respectively) and HA-NS3/4A. The transfected cells were treated with VX-950 (0.2 mM) or left untreated for 1 day before immunoblot analysis with anti-Flag or anti-HA.

  • VX950, a HCV NS3/4A protease inhibitor, abrogates cleavage of C4 induced by HCV NS3/4A protease. VX950 was added to HCV NS3/4A protease at the indicated concentrations, and then C4 was added. Proteins were separated by SDS-PAGE for CBB staining. The three C4-derived fragments of 17 kDa and 15 kDa produced by NS3/4A protease action could not be detected after pretreatment with VX950, and this change was accompanied by an increased concentration of the 32-kDa C4γchain.

    The toxicity of BMS-790052 (BMS) and Telaprevir (TPV) was measured by seeding 96-well plates to 70% confluence and exposing the cells to up to 50 μM of compound for 72 hours. MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] was added to each well at a final concentration of 500 μg/ml 4 h before dissolving crystals in 100 μl of DMSO and measuring at 550 nm UV wavelengths. The 50% cytotoxic concentration (CC50) was then calculation using the OD550 value and the following formula: log CC50=log concentration of HPP-[(HPP-50)/(HPP-LPP)×log d HPP: highest protective percentage closest to 50% LPP: Lowest protective percentage closest to 50% d: dilution factor

HCV Protease阻害剤の選択性比較

生物活性

製品説明 Telaprevir(VX-950)は、C型肝炎ウイルス(HCV)NS3-4Aセリン・プロテアーゼ阻害剤で、IC50 が0.35 μMになる。
特性 Telaprevir is a covalent, reversible inhibitor of the NS3-4A protease (unlike BILN 2061which is a noncovalent inhibitor), with a slow-binding and slow-dissociation mechanism.
ターゲット
HCV NS3-4A serine protease [1]
0.35 μM
体外試験

Telaprevir inhibits the hepatitis C virus NS3-4A serine protease, leading to the block of viral polyprotein processing and subsequently decrease of viral RNA replication, total HCV RNA levels and protein levels in the Con1 (genotype 1b) subgenomic HCV replicon cells in a time- and dose-dependent manner. Telaprevir displays a significant time-dependent increase in inhibitory effect on the replication of HCV RNA with IC50 values of 0.574 μM, 0.488 μM, 0.210 μM and 0.139 μM for 24, 48, 72 and 120 hours incubation, respectively. Telaprevir displays an average IC50 of 0.354 μM and an average IC90 of 0.830 μM, respectively, from three independent experiments using the 48 hours incubation. Telaprevir has no significant cytotoxicity to HCV replicon cells, parental Huh-7 and HepG2 cells after 48 hours incubation. Telaprevir (17.5 μM) completely eradicates HCV RNA from replicon cells after 13 days incubation without rebound after Telaprevir is withdrawn. Telaprevir displays an additive to moderate synergistic effect on reduction of HCV RNA replication and suppression of resistance mutations without significant increase in cytotoxicity when in combination with IFN-α, compared to treatment with each agent alone. [1]

体内試験 Oral administration of Telaprevir reduces HCV protease-dependent cleavage and subsequent secretion of SEAP from the liver into the blood in the mice model to 18.7% and 18.4% at dosage of 10 and 25 mg/kg, respectively. [2] Administration of Telaprevir at 200 mg/kg for 1 week results in a 1.9 log reduction of HCV RNA in genotype 1b HCV-infected human hepatocyte chimeric mice, and when treatment in combination with MK-0608 (50 mg/kg) for 4 weeks, viruses are eliminated from mice.

Determination of anti-HCV activity:

Stable Huh-7 cells containing the self-replicating, subgenomic HCV replicon, which is identical in sequence to the I377neo/NS3-3'/wt replicon are used for anti-HCV assays. Replicon cells are incubated at 37 °C for the indicated period of time with Telaprevir serially diluted in DMEM plus 2% FBS and 0.5% dimethyl sulfoxide (DMSO). Total cellular RNA is extracted using an RNeasy-96 kit, and the copy number of HCV RNA is determined using a quantitative RTPCR (QRT-PCR) assay for the assessment of 50% inhibitory concentration (IC50
