It is an inhibitor of dihydroorotate dehydrogenase, an enzyme that is required for de novo pyrimidine biosynthesis. The compound exhibits antineoplastic and antiviral properties. It has a role as an EC 1.3.5.2 [dihydroorotate dehydrogenase (quinone)] inhibitor, an immunosuppressive agent, an antineoplastic agent, an antiviral agent, a pyrimidine synthesis inhibitor, an anticoronaviral agent and an antimetabolite. It is a member of biphenyls, a member of monofluorobenzenes, a quinolinemonocarboxylic acid and a monocarboxylic acid. It is a conjugate acid of a brequinar(1-)."}]
