abstract = {Compound repurposing is an important strategy for the
identification of effective treatment options against
SARS-CoV-2 infection and COVID-19 disease. In this regard,
SARS-CoV-2 main protease (3CL-Pro), also termed M-Pro, is an
attractive drug target as it plays a central role in viral
replication by processing the viral polyproteins pp1a and
pp1ab at multiple distinct cleavage sites. We here report
the results of a repurposing program involving 8.7 K
compounds containing marketed drugs, clinical and
preclinical candidates, and small molecules regarded as safe
in humans. We confirmed previously reported inhibitors of
3CL-Pro and have identified 62 additional compounds with
IC50 values below 1 μM and profiled their selectivity
toward chymotrypsin and 3CL-Pro from the Middle East
respiratory syndrome virus. A subset of eight inhibitors
showed anticytopathic effect in a Vero-E6 cell line, and the
compounds thioguanosine and MG-132 were analyzed for their
predicted binding characteristics to SARS-CoV-2 3CL-Pro. The
X-ray crystal structure of the complex of myricetin and
SARS-Cov-2 3CL-Pro was solved at a resolution of 1.77 Å,
showing that myricetin is covalently bound to the catalytic
Cys145 and therefore inhibiting its enzymatic activity.},
