Mycophenolate mofetil may also be used off-label as a second-line treatment for autoimmune hepatitis that has not responded adequately to first-line therapy. Other off-label uses of this drug include lupus-associated nephritis and dermatitis in children.
Mycophenolate mofetil is an inosine monophosphate dehydrogenase inhibitor used to prevent the rejection of kidney, heart, or liver transplants.
The active metabolite of mycophenolate, mycophenolic acid, prevents T-cell and B-cell proliferation and the production of cytotoxic T-cells and antibodies. Lymphocyte and monocyte adhesion to endothelial cells of blood vessels that normally part of inflammation is prevented via the glycosylation of cell adhesion molecules by MPA. MPA inhibits de novo purine biosynthesis (that promotes immune cell proliferation) by inhibiting inosine 5’-monophosphate dehydrogenase enzyme (IMPDH), with a preferential inhibition of IMPDH II. IMPDH normally transforms inosine monophosphate (IMP) to xanthine monophosphate (XMP), a metabolite contributing to the production of guanosine triphosphate (GTP). GTP is an important molecule for the synthesis of ribonucleic acid (RNA), deoxyribonucleic acid (DNA), and protein. As a result of the above cascade of effects, mycophenolate mofetil reduces de-novo production of guanosine nucleotides, interfering with the synthesis of DNA, RNA, and protein required for immune cell production. Further contributing to the above anti-inflammatory effects, MMF depletes tetrahydrobiopterin, causing the decreased function of inducible nitric oxide synthase enzyme, in turn decreasing the production of peroxynitrite, a molecule that promotes inflammation.
