Chemical Information
Nirmatrelvir is an azabicyclohexane that is (1R,5S)-3-azabicyclo[3.1.0]hexane substituted by {(1S)-1-cyano-2-[(3S)-2-oxopyrrolidin-3-yl]ethyl}aminoacyl, 3-methyl-N-(trifluoroacetyl)-L-valinamide, methyl and methyl groups at positions 2S, 3, 6 and 6, respectively. It is the first orally administered inhibitor of SARS-CoV-2 main protease developed by Pfizer and used in combination with ritonavir for the treatment of COVID-19. It has a role as an EC 3.4.22.69 (SARS coronavirus main proteinase) inhibitor and an anticoronaviral agent. It is a secondary carboxamide, a tertiary carboxamide, an azabicyclohexane, a nitrile, an organofluorine compound, a pyrrolidinecarboxamide and a member of pyrrolidin-2-ones.
