Description: Grazoprevir, also known as MK5172, is a drug approved for the treatment of hepatitis C. It was developed by Merck and completed Phase III trials, following promising results in Phase II when used in combination with the NS5A replication complex inhibitor elbasvir, either with or without ribavirin.Grazoprevir is a second generation hepatitis C virus protease inhibitor acting at the NS3/4a protease targets. It has good activity against a range of HCV genotype variants, including some that are resistant to most currently used antiviral medications.

Additional Information

MK-5172, is a Next Generation HCV NS3/4a Protease Inhibitor with a Broad HCV Genotypic Activity Spectrum and Potent Activity Against Known Resistance Mutants, in Genotype 1 and 3 HCV-Infected Patients. MK-5172 exhibits excellent selectivity over other serine proteases such as elastase and trypsin (no measurable inhibition), and shows only modest inhibitory potency with chymotrypsin (IC50 = 1.5 µM; 75,000-fold selective). In the genotype 1b replicon assay, MK-5172 potently inhibits viral replication (IC50 = 2 nM) and demonstrates a modest shift in the presence of 50% NHS (EC50 = 9.5 nM). In vitro, MK-5172 inhibits the NS3/4A enzyme from genotypes 1b, 2a, 2b, and 3a with Ki values of <0.02, 0.15, 0.02, and 0.7 nM, respectively. The genotype 2a replicon is also potently inhibited by MK 5172 (EC50 = 5 nM).
