mykofeenolihappo

Mykofeenolihappo, known scientifically as mycophenolic acid, is a naturally occurring compound produced by several species of Penicillium fungi. It is a potent inhibitor of inosine monophosphate dehydrogenase (IMPDH), an enzyme crucial for the de novo synthesis of purines. This inhibitory effect makes mycophenolic acid valuable in medicine, particularly as an immunosuppressant.

Its primary medical application is in preventing organ transplant rejection. By reducing the proliferation of lymphocytes, which are critical components of the immune system responsible for rejecting foreign tissues, mycophenolic acid helps to suppress the immune response. It is often administered in combination with other immunosuppressive drugs.

Mykofeenolihappo was first isolated in the late 19th century, but its pharmacological properties were not fully understood until much later. The development of its synthetic derivative, mycophenolate mofetil, which is a prodrug that is converted to mycophenolic acid in the body, significantly improved its bioavailability and therapeutic use. Mycophenolate mofetil is now widely prescribed for renal, cardiac, and hepatic transplant recipients.

Beyond transplantation, research has explored its potential in treating autoimmune diseases, such as lupus and rheumatoid arthritis, where an overactive immune system plays a significant role. However, like all potent medications, it has potential side effects that require careful monitoring by healthcare professionals.
