Findings establish that both catalytic and allosteric sites play essential roles in regulating 3CL pro function, and targeting allosteric regions such as the Asn28-associated pocket offers a promising approach for antiviral development.
The findings provide mechanistic insights into a key allosteric mechanism for Mpro inhibition but also provide a promising chemical scaffold for further development as an Mpro-targeting inhibitor.
