Mycophenolic acid是一种免疫抑制剂,用于预防器官移植排斥。Mycophenolic acid 也是一种有效的非竞争性肌苷单磷酸脱氢酶 (IMPDH) 抑制剂,EC50 为 0.24 µM,可抑制肝癌类器官的生长。Mycophenolic acid (mycophenolate) is derived from the fungus Penicillium stoloniferum. Mycophenolate mofetil is metabolised in the liver to the active moiety mycophenolic acid. Mycophenolic acid (mycophenolate) inhibits inosine monophosphate dehydrogenase, the enzyme that controls the rate of synthesis of guanine monophosphate in the de novo pathway of purine synthesis used in the proliferation of B and T lymphocytes.Mycophenolic acid (mycophenolate) is potent and can be used in place of the older anti-proliferative azathioprine. Mycophenolic acid (mycophenolate) is usually used as part of a three-compound regimen of immunosuppressants, also including a calcineurin inhibitor (ciclosporin or tacrolimus) and prednisolone.
