Vaniprevir (MK-7009) is an non-covalent competitive macrocyclic inhibitor of Hepatitis C virus NS3/4A protease genotype 1a and 1b proteases at subnanomolar concentrations with modestly shifted potency against genotype 2a and 2b proteases at low nanomolar concentrations. Merck & Co. developed vaniprevir in combination with standard therapy for the twice-daily treatment of hepatitis C virus infections. The product has been launched in Japan under name VANIHEP, and Merck reported in its 2014 annual report that the product will only be available in this region.

Sample Use Guides

In Vivo Use Guide

In general, for adults 2 VANIHEP Capsules 150mg (Vaniprevir) (300 mg as the active ingredient) at a time, twice a day for 12 weeks or 24 weeks. This medicine is used in combination with peginterferon α-2b (gene recombination) and ribavirin.

Route of Administration: Oral

In Vitro Use Guide

In a cell-based HCV replicon assay, Vaniprevir (MK-7009) showed potent activity against the genotype 1b enzyme (EC50 5 nM). In a genotype 2a replicon, the potency of MK-7009 was reduced only modestly (EC50 15 nM).
