Antiviral; SARS-CoV-2 Mpro inhibitor

Functions

Boceprevir directly inhibits Hepatitis C virus (HCV) NS3 protease (overall binding constant for formation of covalent adduct, Ki* = 14 nM; initial inhibition constant Ki = 7.8 µM). This blocks NS3 autoactivation, and subsequent cleavage and maturation of other viral proteins necessary for replisome assembly. This reversible, slow-binding ketoamide also restores host interferon signaling obstructed by HCV, thus reactivating the immune response. Recently, it was also found to inhibit the key SARS-CoV-2 protease, Mpro (3CLpro) in vitro (Ki = 1.18 µM) and in cells (EC50 = 1.9 µM, virus-induced cytopathic effects (CPE)

Application Procedures

First dissolved in DMSO (up to at least 15 mg/ml); or Ethanol (25 mg/ml), then diluted to aqueous buffer. Solutions in DMSO may be stored at -20°C for up to 3 months.
