Sirolimus, also known as rapamycin, is an immunosuppressant drug primarily used to prevent organ transplant rejection. It works by inhibiting the mTOR (mechanistic target of rapamycin) pathway, which reduces the activity of immune cells, thereby dampening the body's immune response. Additionally, sirolimus has antiproliferative effects, which can also help in treating certain types of cancer and other conditions.
