Danoprevir

Danoprevir (INN)[1] is an orally available[2] 15-membered macrocyclic peptidomimetic inhibitor of NS3/4A HCV protease.[3] It contains acylsulfonamide, fluoroisoindole and tert-butyl carbamate moieties. Danoprevir is a clinical candidate based on its favorable potency profile against multiple HCV genotypes 1–6 and key mutants (GT1b, IC50 = 0.2–0.4 nM; replicon GT1b, EC50 = 1.6 nM).[4]
