mykophenolic

Mycophenolic is a term that can refer to several related concepts, primarily concerning a group of secondary metabolites produced by fungi, and by extension, certain pharmaceutical compounds derived from them.

In mycology, mycophenolic refers to compounds belonging to the mycophenolic acid family. These are often produced by Penicillium species and other fungi. Mycophenolic acid itself is a natural product that exhibits antimicrobial and antitumor properties. Its discovery and characterization have been significant in understanding fungal biochemistry and potential therapeutic applications.

In pharmacology, the term mycophenolic is most commonly associated with mycophenolate mofetil and mycophenolic acid. Mycophenolate mofetil is an immunosuppressant drug. It is a prodrug that is rapidly converted to mycophenolic acid in the body. Mycophenolic acid acts as an inhibitor of inosine monophosphate dehydrogenase (IMPDH), an enzyme crucial for the synthesis of guanosine nucleotides. By blocking this pathway, it effectively suppresses the proliferation of lymphocytes, which are key components of the immune system. This property makes mycophenolate mofetil a valuable medication for preventing organ rejection after transplantation (such as kidney, liver, and heart transplants) and for treating autoimmune diseases like lupus. The term mycophenolic, in this context, directly relates to the active pharmacological agent.
