Potent inhibitors of SARS-CoV-2 3C-like protease derived from N-substituted isatin compounds.

ABSTRACT: SARS-CoV-2 3C-like protease is the main protease of SARS-CoV-2 and has been considered as one of the key targets for drug discovery against COVID-19. We identified several N-substituted isatin compounds as potent SARS-CoV-2 3C-like protease inhibitors. The three most potent compounds inhibit SARS-CoV-2 3C-like protease with IC₅₀'s of 45 nM, 47 nM and 53 nM, respectively. Our study indicates that N-substituted isatin compounds have the potential to be developed as broad-spectrum anti-coronavirus drugs.
