Ciluprevir

Ciluprevir is an effective and selective HCV NS3 protease inhibitor with proven antiviral effect in humans. Ciluprevir may be an antiviral agent for individuals infected with non-genotype-1 HCV. In vitro sensitivity studies with Ciluprevir showed a decrease in affinity for proteases of genotypes 2 and 3 (Ki: 80 to 90 nM) compared to genotype 1 enzymes (Ki: 1.5 nM).
