WebThiopurine methyltransferase (TPMT) is the primary enzyme responsible for thiopurine drugs (azathioprine, 6-mercaptopurine and 6-thioguanine) metabolism. These drugs are converted in the body to thioguanine nucleotides (TGNs). Thiopurine therapy targets the replicating cells without overly harming normal cells. WebTests&Tubes0246. Additional Information. Thiopurine drugs (azathioprine and 6-mercaptopurine) are converted in vivo to cytotoxic thionucleotides which cause white cell supression. The enzyme TPMT provides a major catabolic pathway for these drugs. In the absence of TPMT activity there will be an over-dose effect, resulting in complete bone ... hotwatts imgur

WebThiopurine Pharmacology. The pro-drug AZA is converted by glutathione to 6MP. 3 The three key enzymes involved in 6MP metabolism are xanthine oxidase (XO), thiopurine S-methyltransferase (TPMT) and hypoxanthine phosphoribosyltransferase (HPRT). Thiopurine catabolism via the XO pathway leads to the production of the inactive … Webefficacy and drug toxicity of thiopurine drugs.
