Abstract
SARS-CoV-2 3CL protease (3CLpro) is essential for coronavirus replication and of great interest as an antiviral drug target. Here, the authors show that the naturally occurring flavonoid myricetin is a non-peptidomimetic and covalent inhibitor of 3CLpro, and they solve crystal structures of 3CLpro with myricetin and derivatives, which reveal that the pyrogallol group covalently modifies the catalytic cysteine.
