| + | The main protease (M(pro) ) of SARS-CoV-2 is a well-characterized target for antiviral drug discovery. To date, most antiviral drug discovery efforts have focused on the S4-S1' pocket of M(pro) ; however, it is still unclear whether the S1'-S3' pocket per se can serve as a new site for drug discovery. In this study, the S1'-S3' pocket of M(pro) was found to differentially recognize viral peptidyl substrates. For instance, S3' in M(pro) strongly favors Phe or Trp, and S1' favors Ala. The peptidyl inhibitor D-4-77, which possesses an alpha-bromoacetamide warhead, was discovered to be a promising inhibitor of M(pro) , with an IC(50) of 0.95 muM and an antiviral EC(50) of 0.49 muM. The M(pro) /inhibitor co-crystal structure confirmed the binding mode of the inhibitor to the S1'-S3' pocket and revealed a covalent mechanism. In addition, D-4-77 functions as an immune protectant and suppresses SARS-CoV-2 M(pro) -induced antagonism of the host NF-kappaB innate immune response. These findings indicate that the S1'-S3' pocket of SARS-CoV-2 M(pro) is druggable, and that inhibiting SARS-CoV-2 M(pro) can simultaneously protect human innate immunity and inhibit virion assembly. | ||
