It is a 3C-like protease inhibitor of MERS-CoV and SARS-CoV. It has a role as an anticoronaviral agent and an EC 3.4.22.69 (SARS coronavirus main proteinase) inhibitor. It is a tripeptide, a member of pyrrolidin-2-ones, a tert-butyl ester, an ethyl ester, an enoate ester and a secondary carboxamide."}]
