Allopurinol reduces excessive 6-methyl-mercaptopurine (6-MMP) while enhancing 6-thioguanine (6-TGN) levels. The aim of this study was to evaluate clinical, metabolic and endoscopic impact of allopurinol in combination with low-dose thiopurine in IBD. Thiopurine‐induced pancreatitis occurs in approximately 4% of patients 38 and has been considered a strict contraindication to subsequent treatment with an alternative thiopurine. 75 Three small retrospective case series (< 10 patients each) have examined rechallenging patients with 6MP after AZA‐induced pancreatitis, with overall success rates varying from 29% to 100%. 76-78 There are no Catalyzes the S-methylation of thiopurine drugs such as 6-mercaptopurine (also called mercaptopurine, 6-MP or its brand name Purinethol) using S-adenosyl-L-methionine as the methyl donor (PubMed:18484748). TPMT activity modulates the cytotoxic effects of thiopurine prodrugs. A natural substrate for this enzyme has yet to be identified.

Drug Metab Dispos. Abstract: Drug repositioning is the application of the existing drugs to new uses and has the potential to reduce the time and cost required for the typical drug discovery process. In this study, we repositioned thiopurine drugs used for the treatment of acute leukaemia as new tyrosinase inhibitors. There was evidence for a cumulative effect of the variants on enzymatic activity and drug tolerance.

Excessive methylation via thiopurine methyltransferase (TPMT) frequently causes therapeutic failure. Allopurinol reduces excessive 6-methyl-mercaptopurine (6-MMP) while enhancing 6-thioguanine (6-TGN) levels. The aim of this study was to evaluate clinical, metabolic and endoscopic impact of allopurinol in combination with low-dose thiopurine in IBD.

The thiopurine drugs, 6-mercaptopurine (6-MP), 6-thioguanine (6-TG) are commonly used cytotoxic agents. A derivative of 6-MP, azathioprine, is commonly used as an immunosuppressant. A prominent route for the metabolism of these agents is mediated by the enzyme thiopurine methyltransferase (TPMT). This enzyme exhibits considerable inter-individual variation in activity, partly due to the

They are also used as immunosuppressants after organ transplantation. As well as mercaptopurine, the most common thiopurine drugs are azathioprine and thioguanine. What is being tested? The precise mechanism of action of thiopurine drugs remains unclear despite more than 40 years of use.
