Biological Activity

MK-7845 is a potent, reversible covalent SARS-CoV-2 3CLPro inhibitor with IC50 of 8.7 nM, inhibits wild-type SARS-CoV-2 3CLPro in SARS-CoV-2 reporter replicon assay in A549 cells with IC50 of 15 nM.
MK-7845 isplays 82-fold to >1000-fold selectivity agianst a panel of host-cell proteases.
MK-7845 otently inhibits P132H mutant 3CLPro present in the Omicron variant with IC50 of 15 nM.
MK-7845 hows similar activity against the parental WA1/2020, Delta, and Omicron strains of the virus with EC50 value of 215 nM-444 nM.
MK-7845 showed significant and dose-dependent reductions in viral load beginning at 250 mg/kg in mouse model of SARS-CoV-2 infection.
