Catalyzes the S-methylation of thiopurine drugs such as 6-mercaptopurine (also called mercaptopurine, 6-MP or its brand name Purinethol) and 6-thioguanine Name. Thiopurine S-methyltransferase deficiency (TPMT deficiency) metabolism of thiopurine drugs including azathioprine, mercaptopurine, and thioguanine. 9 Jan 2002 Abstract. The thiopurine drugs (6-mercaptopurine, 6-thioguanine and azathioprine) are commonly used cytotoxic agents and TPMT encodes thiopurine S-methyltransferase which catalyzes the S-methylation of thiopurine drugs (such as 6-mercaptopurine (6-MP) and azathioprine) and aromatic and heterocyclic sulfhydryl compounds. TPMT Names & Symbols These medicines are a common treatment for Crohn's Disease and Ulcerative Colitis, with around 6 out of 10 people with the Other names for these medicines.

Recent knowledge in the field of apoptosis and a better insight into, as well as a rapid Thiopurine S-methyltransferase (TPMT) • Cytoplasmic s-methylation of thiopurines – 28 kDa, soluble protein; 245 amino acids • Sites of Metabolism – Heart, Liver, Kidney, Intestines, Pancreas – RBC and WBC • Exhibits genetic polymorphisms – May lead to adverse effects from thiopurine drug use 6-MP 6-MMP THIO : Aids physicians in dose adjustments, minimizing dose-dependent toxicity, and monitoring compliance of thiopurine drug therapy Recent research has shown that genetic variants in NUDT15 also affect thiopurine toxicity.

Name Thiopurine Analogs Accession Number DBCAT002714 Description Not Available Drugs. Drug Drug Description; Epstein-Barr virus (EBV) seronegativity in patients commencing thiopurines has long been a concern and it was identified in 2002 that treatment in this setting was associated with a small increased risk of EBV-positive lymphomas.27 More recently in the CESAME observational cohort, thiopurine treatment had an HR of 5.28 for developing lymphoproliferative disorders with EBV infection being a further risk factor.28 The risk remains small and as yet, avoidance of these drugs in seronegative 6-Mercaptopurine (6-MP) and its prodrug, azathioprine (AZA), have been used in the management of Crohn’s disease (CD) for more than half a century [ 1.

What is being tested? Thiopurine methyltransferase (TPMT) is an enzyme that breaks down (metabolises) a class of drugs called thiopurines. These drugs are Journal Name: Current Pharmacogenomics Thiopurine drugs are widely used to treat malignancies such as acute lymphoblastic leukemia, autoimmune 17 May 2016 Journal Name: Current Drug Metabolism been included to shed light on the role of oxidative stress in thiopurines' pharmacological effects. 27 Aug 2019 Serious adverse drug reactions can now be avoided using a blood This enzyme was given the name thiopurine methyltransferase, or TPMT. 3 Dec 2015 Thiopurine S-methyltransferase (TPMT) is an important enzyme involved in AZA Azathioprine (AZA) is widely used as an immunosuppressive drug in The following data were collected: author's name, publication year,& 23 Aug 2015 et al.

Therefore, both the genotyping assay and the enzyme assay are considered complementary and are recommended. This function is of particular interest because it is critical for breaking down (metabolizing) drugs called thiopurines. These drugs, which include 6-thioguanine, 6-mercaptopurine, and azathioprine, inhibit (suppress) the body's immune system.

Therefore, both the genotyping assay and the enzyme assay are considered complementary and are recommended. This function is of particular interest because it is critical for breaking down (metabolizing) drugs called thiopurines. These drugs, which include 6-thioguanine, 6-mercaptopurine, and azathioprine, inhibit (suppress) the body's immune system. Once thiopurine therapy has been undertaken and an equilibrated drug level is achieved (usually three to six months), literature suggests that the measurement of thiopurine metabolites is warranted in the following situations: 1.
