Biologische Aktivität
Ki: 8.6 nM (SARS-CoV-2 main protease)[1]
Leritrelvir (RAY1216) has a drug-target residence time of 104 min[1].
Leritrelvir is covalently attached to the catalytic Cys145 through the α-ketoamide warhead[1].
Leritrelvir (0-1000 nM; 72 h) shows antiviral activities against SARS-CoV-2 wild type ancestral strain and variants[1].

Cell Line:Vero E6 cells inoculated with SARS-CoV-2 WT, Alpha, Beta, Delta, Omicron BA.1 and Omicron 247 BA.5 strains
-
Concentration:0-1000 nM
-
Incubation Time:72 h
