Description and Uses

Mycophenolic acid is an immunosuppresive microbial metabolite that has been found in P. brevicompactum. It is also an active metabolite of mycophenolate mofetil that is formed via carboxylesterase 1 (CES1) and CES2. Mycophenolic acid is an inhibitor of IMP dehydrogenase (IMPDH) type I and type II (IC₅₀s = 32 and 11 nM, respectively, in cell-free assays) and inhibits DNA synthesis in L strain mouse fibroblasts when used at concentrations ranging from 0.1 to 10 μg/ml. It is active against several strains of C. albicans, C. parakrusei, C. tropicalis, and C. neoformans (MICs = 3.9-31.25 μg/ml), as well as various strains of S. aureus (MICs = 31.25-125 μg/ml). Mycophenolic acid (150 mg/kg) reduces splenomegaly in a mouse model of Friend virus-induced leukemia. It decreases the number of hemolytic plaque forming cells isolated from the spleen of mice immunized with sheep red blood cells (RBCs) when administered at doses ranging from 60 to 240 mg/kg. Formulations containing mycophenolic acid have been used as immunosuppressive agents in the prevention of organ transplant rejection.

Mycophenolic acid is a common Penicillium metabolite first reported in the 1930s as a possible mycotoxin. Re-investigation showed mycophenolic acid to display broad antitumour, antiviral, antifungal and antiprotozoan activities. Its potent immunosuppressant activity led to its commercial development to prevent kidney transplant rejection. Mycophenolic acid acts by inhibiting inosine monophosphate dehydrogenase, controlling the rate of de novo purine synthesis in proliferating B and T lymphocytes.
