The structural formula of Azathioprine is: It is an imidazolyl derivative of 6-mercaptopurine and many of its biological effects are similar to those of the parent compound. Azathioprine, USP is a pale yellow, odorless powder. Sixty per cent of patients with IBD receive thiopurines (azathioprine (AZA), mercaptopurine (MP) and to a lesser extent tioguanine) with proven efficacy in maintaining steroid-free remission.1 Although the evidence for the use of thiopurines in UC is not as strong as in patients with CD, it has been demonstrated that in patients with steroid-dependent UC, 53% achieved steroid-free remission on AZA compared with 21% on aminosalicylates.2 Therefore, thiopurines are recommended once a patient *Chevaux JB, Peyrin-Biroulet L, Sparrow MP.

These drugs, which include 6-thioguanine, 6-mercaptopurine, and azathioprine, inhibit (suppress) the body's immune system. Thiopurine drugs are used to treat some autoimmune disorders, including Crohn disease and rheumatoid arthritis, which occur when the immune system malfunctions.

Two other thiopurine drugs, mercaptopurine and azathioprine, were also evaluated for their tyrosinase inhibition; mercaptopurine caused stronger inhibition than thioguanine did, whereas azathioprine was a poor inhibitor. The inhibitory constant of mercaptopurine (16 μM) was comparable to that of the well-known inhibitor kojic acid (13 μM). Both mesalamine (Asacol and other brand names) and sulfasalazine (Azulfidine) belong to the class of drugs known as aminosalicylates, which are different from thiopurines. They work by reducing inflammation in the intestine. For this study, the authors revisited the same dataset, looking at nearly 1,500 IBD cases from 47 countries. The thiopurines, azathioprine and 6 MP are potent inhibitors of both experimental and clinical immune responses.

Mercaptopurine. Azathioprine. The thiopurine drugs are purine antimetabolites widely used in the treatment of acute lymphoblastic leukemia, autoimmune disorders (e.g., Crohn's disease, rheumatoid arthritis ), and organ transplant recipients. Physiology Thiopurine drugs are purine antimetabolites and include Azathioprine (AZA) (Imuran) 6-mercaptopurine (6-MP) Azathioprine (AZA) (Imuran) 6-mercaptopurine (6-MP) (Purinethol) 6-thioguanine (6-TG) (Tabloid) Thiopurines must be metabolized to 6-thioguanine nucleotides (6-TGN) for These drugs are widely used to treat leukemias and autoimmune disorders such as inflammatory bowel disease (Crohn's disease and ulcerative colitis) and arthritis. They are also used as immunosuppressants after organ transplantation. As well as azathioprine the most common thiopurine drugs are mercaptopurine and thioguanine. What is being tested?

2016-08-29 · Allopurinol is a safe drug with the main side effects including rashes and gastrointestinal (GI) symptoms but it can rarely (1:100 000) cause life-threatening toxic epidermal necrolysis.24 A PRACTICAL GUIDE TO THIOPURINE TREATMENT Prior to commencing thiopurines, patients should be screened to help prevent opportunistic infections as In this study, we repositioned thiopurine drugs used for the treatment of acute leukaemia as new tyrosinase inhibitors. Tyrosinase catalyses two distinct and successive oxidations in melanin biosynthesis: the conversions of tyrosine to dihydroxyphenylalanine (DOPA) and DOPA to dopaquinone.
