ensitrelvir is an approved drug (Japan 2022)
Compound class: Synthetic organic
Comment: Ensitrelvir is a newly proposed INN for an antiviral that was revealed in January 2022, in the COVID special section of Proposed List 126. It was therefore assumed to target SARS-CoV-2, and to be a potential drug for the treatment of patients with SARS-CoV-2 infection (COVID-19). We were able to match this chemical structure to the Shiongi lead compound S-217622, following their preprint disclosure. The Shiongi article was subsequently published in J Med Chem in March 2022 [3]. S-217622 is described as a non-covalent oral Mpro inhibitor, with pharmacokinetics that support once-daily dosing. It was formulated as a 1:1 fumaric acid complex. Molecular dynamics simulation has been used to estimate ensitrelvir's effectiveness against 6 common SARS-CoV-2 variants (Alpha AP.1, Beta B.1.351, Gamma P.1.13, Delta AY.116, Omicron BA.1/2/3/4/5 and Lambda C.37) [4].
