Mycophenolic Acid (MPA) is a potent immunosuppressive agent that revolutionized transplant medicine and the treatment of autoimmune diseases. Originally derived from the Penicillium mold (Penicillium stoloniferum), it is primarily used to prevent organ rejection.
In the pharmaceutical industry, it is most commonly encountered as its prodrug form, Mycophenolate Mofetil (MMF), or as Mycophenolate Sodium.
