    • Chemical Class:

      A thiopurine that is 6-mercaptopurine in which the mercapto hydrogen is replaced by a 1-methyl-4-nitroimidazol-5-yl group. It is a prodrug for mercaptopurine and is used as an immunosuppressant, presc ribed for the treatment of inflammatory conditions and after organ transplantation and also for treatment of Crohn's didease and MS.

      Azathioprine(Azasan, Imuran; BW 57-322) is a drug that suppresses the immune system and is used in organ transplantation and autoimmune disease. ;Target: Azathioprine is an immunosuppressive antimetabolite pro-drug. It is an imidazolyl derivative of 6-mercaptopurine and many of its biological effects are similar to those of the parent compound. Azathioprine is converted into 6-mercaptopurine in the body where it blocks purine metabolism and DNA synthesis. Thus it most strongly affects proliferating cells, such as the T cells and B cells of the immune system. The main adverse effect of azathioprine is bone marrow suppression, which can be life-threatening, especially in people with a genetic deficiency of the enzyme thiopurine S-methyltransferase. It is also listed by the International Agency for Research on Cancer as a Group 1 carcinogen (carcinogenic to humans) [1-3]. MedChem Express HY-B0256
