Background:

Ensitrelvir (S-217622) fumarate is the first orally active non-covalent, non-peptidic, SARS-CoV-2 3CL protease inhibitor (IC50=13 nM)[1][2].

In a cytopathic effect (cpe)-inhibition assay of SARS-CoV-2 infected VeroE6/TMPRSS2 cells, Ensitrelvir fumarate shows the EC50 values are approximately 0.4 μM for both wild-type virus and Alpha, Beta, Gamma and Delta variants. EC50 values for SARS-CoV and MERS-CoV were 0.21 and 1.4 μM respectively[1].

Ensitrelvir fumarate dose-dependently inhibits intrapulmonary replication of SARS-CoV-2 in mice[2].
