Rapamycin Description

Rapamycin is a macrolide compound used to cover coronary stents, prevent organ transplant rejection and treat a rare lung disease called lymphangioleiomyomatosis. It has an immunosuppressive function in the human body and is particularly useful in preventing kidney transplant rejection. Rapamycin was first evaluated as an antifungal agent but is now studied for its potent immunosuppressive and antiproliferative properties.

Rapamycin is used in clinical settings to prevent rejection in organ transplantation and to treat certain types of cancer.
