8、razoprevir is potent against a panel of HCVreplication mutants NS5A (Y93H) (EC50=0.70.3 nM), NS5B nucleosides (S282T) (EC50=0.30.1 nM), and NS5B(C316Y) (EC50=0.40.2)1. Grazoprevir (MK-5172) maintains the excellent potency against the gt 3a enzyme as well asa broad panel of mutant enzymes, has excell

When dosed todogs, Grazoprevir (MK-5172) shows low clearance of 5 mL/min/

10、kg and a 3 h half-life after iv dosing and has good plasma exposure (AUC=0.4 M h) after a 1 mg/kg oral dose. Dog liver biopsy studies showed that the liverconcentration of Grazoprevir after the 1 mg/kg oral dose is 1.4 M at the 24 h time point. Similar to its behavior inrats, Grazoprevir demonstrate
