Compound class: Synthetic organic
Comment: Asunaprevir (BMS-650032) is an orally bioavailable, oligopeptide-based inhibitor of the nonstructural protein 3 (NS3), from hepatitis C virus (HCV) [4]. NS3, is a serine protease that is essential for proteolytic cleavages within the HCV polyprotein, a function that is key during HCV viral RNA replication. More recently asunaprevir has been reported to inhibit the papain-like protease (PL-pro, nsp3) in a number of coronaviruses [2].

Bioactivity Comments
Asunaprevir exhibits strong antiviral activity against HCV genotypes 1 and 4, but much weaker activity against genotypes 2 and 3 [1]. It also inhibits PL-pro (IC50s in brackets) from MERS-CoV (41.8 μM), SARS-CoV (47.8 μM) and SARS-CoV-2 (53.9 μM) [2].
