| Uses | PSI-353661 (GS-558093) is a purine nucleotide NS5B polymerase inhibitor against HCV infection. PSI-353661 shows EC90s of 8 nM and 11 nM for wild type and S282T resistant replicons of HCV. PSI-353661 can produce high concentrations of the active triphosphate in primary human hepatocytes[1][3]. | | in vivo | PSI-353661 (50 mg/kg, p.o., together with 400 mg/kg of Telaprevir (HY-10235), daily for 4 weeks) is effective against human hepatocyte chimeric mice infected with HCV[3].
| Animal Model: | Human hepatocyte chimeric mice infected with HCV | | Dosage: | 50 mg/kg, together with 400 mg/kg of Telaprevir | | Administration: | Oral administration (p.o.) | | Result: | Achieved sustained eradication of the mutant virus or the end-of-treatment response.
Reduced serum levels of HCV RNA.
