Mycophenolate mofetil is a carboxylic ester resulting from the formal condensation between the carboxylic acid group of mycophenolic acid and the hydroxy group of 2-(morpholin-4-yl)ethanol. In the liver, it is metabolised to mycophenolic acid, an immunosuppressant for which it is a prodrug. It is widely used to prevent tissue rejection following organ transplants as well as for the treatment of certain autoimmune diseases. It has a role as an anticoronaviral agent, an immunosuppressive agent, a prodrug and an EC 1.1.1.205 (IMP dehydrogenase) inhibitor. It is an ether, a carboxylic ester, a member of phenols, a gamma-lactone and a tertiary amino compound. It is functionally related to a mycophenolic acid and a 2-(morpholin-4-yl)ethanol.
