Mycophenolate Mofetil Mechanism Of Action
This is the rate limiting enzyme in de novo synthesis of guanosine nucleotides. Mycophenolate mofetil mmf cellcept is a prodrug of mycophenolic acid mpa an inhibitor of inosine monophosphate dehydrogenase impdh.
Immunosuppression Drugs
The active metabolite of mycophenolate mycophenolic acid prevents t cell and b cell proliferation and the production of cytotoxic t cells and antibodies.
Mycophenolate mofetil mechanism of action. Mycophenolate mofetil mmf is absorbed following oral administration and hydrolyzed to mycophenolic acid mpa the active metabolite. Three other mechanisms may also contribute to the efficacy of mpa in preventing allograft rejection and other applications. The mechanism of action pharmacokinetics clinical efficacy adverse effects and dosage and administration of mycophenolate mofetil are reviewed.
Mechanisms of action of mycophenolate mofetil ac allison 2005 skip to main content. Mechanism by which mpa exerts immunosuppressive effects. Mycophenolate mofetil mmf is an immunosuppressive medication commonly used to prevent rejection in solid organ transplant recipients.
Both drugs have a pivotal role in the treatment of various rheumatic diseases. Mpa depletes guanosine nucleotides preferentially in t and b. Mycophenolate mofetil mmf cellcept is a prodrug of mycophenolic acid mpa an inhibitor of inosine 5 monophosphate dehydrogenase.
Mycophenolate mofetil is used to prevent or treat allograft rejection after solid organ transplantation. Active metabolite of mmf mycophenolic acid inhibits inosine monophosphate dehydrogenase which is the rate limiting enzyme in purine synthesis for t and b cell proliferation. Mycophenolic acid was discovered by italian medical scientist bartolomeo gosio gosio collected a fungus from spoiled corn and named it penicillium glaucum.
T and b lymphocytes are more dependent on this pathway than other cell types are. First mpa can induce apoptosis of activated t lymphocytes which may eliminate clones of cells responding to antigenic stimulation. Mycophenolate mofetil is reported to have a pka values of 5 6 for the morpholino moiety and 8 5 for the phenolic group.
Mycophenolate mofetil is the morpholino ethyl ester of mycophenolic acid. The ester masks the carboxyl group. Mycophenolate mofetil and azathioprine inhibit the purine pathway and subsequently diminish cell proliferation.
