Biological Activity for Asunaprevir

Asunaprevir is a potent HCV NS3 protease inhibitor (IC50 = 0.2-3.5 nM). Asunaprevir can be used to control CRIPSR-Cas9 gene editing via the small molecule-assisted shut-off (SMASh) technique, which involves fusion of Cas9 to a peptide comprising a protease domain and a degron tag. Asuprenavir blocks the protease-mediated removal of the degron tag leading to degradation of Cas9 through proteasome and autophagolysosome pathways. It can also be used as a resversible switch to control CAR (chimeric antigen receptor)-T cells, where the CAR has been modified by insertion of a hepatitis C virus nonstructural protein 3 protease (HCV-NS3) between the scFv and the hinge domains. Also inhibits SARS-CoV-2 Mpro activity (IC50 = 15-48.4 μM).
