These drugs, which include 6-thioguanine, 6-mercaptopurine, and azathioprine, inhibit (suppress) the body's immune system. Thiopurine S-methyltransferase. Methylation of MP by TPMT is a critical step in thiopurine metabolism. It was first noted in the 1980s that differences in TPMT activity help account for the variability in tolerance to thiopurines. What is being tested?
14 Sep 2020 The thiopurines (ie,[AZA] and, also known as 6-mercaptopurine [6-MP]) exert a glucocorticoid-sparing effect for patients with inflammatory This includes measurement of thiopurine metabolites for optimising the dose of azathioprine and 6-mercaptopurine. Thiopurines, either Azathioprine (also known Thiopurine methyltransferase (TPMT) is an enzyme that breaks down ( metabolizes) thiopurines. Thiopurines include three medications: 6- mercaptopurine 6 Nov 2016 In the management of IBD, thiopurines [i.e., azathioprine (AZA), mercaptopurine ( MP) and thioguanine (TG)] play an important role in clinical The thiopurine drugs (6-mercaptopurine, 6-thioguanine and azathioprine) are commonly used cytotoxic agents and immunosuppressants.

Thiopurine-related adverse drug reactions are frequent, ranging from 5% up to 40%, in both a dose-dependent and -independent manner. IBD patients with low TPMT activity are at high risk of developing severe haematotoxicity if pharmacogenetically guided dosing is not performed.
2 The answer may
Thiopurine metabolism. Thiopurines are represented by mercaptopurine (MP), azathioprine and thioguanine 20.Both MP and azathioprine are used in paediatrics; these undergo extensive intestinal and hepatic metabolism by a number of enzymes, including hypoxanthine phosphoribosyltransferase (HPRT), TPMT, xanthine oxidase (XO) and inosine monophosphate dehydrogenase (IMPDH).

Genetic polymorphisms that affect this enzymatic activity are correlated with variations in sensitivity and toxicity to such drugs within individuals, causing thiopurine S-methyltransferase deficiency. In addition to polymorphisms in the TPMT gene, 5,6 we recently identified NUDT15 as a novel thiopurine metabolizing enzyme, genetic variation of which strongly influences MP tolerance in children with ALL 7,8 and patients with inflammatory bowel diseases. 9 As a nucleotide diphosphatase, NUDT15 negatively affects MP cytotoxicity by converting the thioguanine triphosphate (TGTP) to thioguanine Appell ML, Berg J, Duley J, et al.
