Thiopurine pathway [PDF]

open access: yesPharmacogenetics and Genomics, 2010
The thiopurine drugs are purine antimetabolites widely used in the treatment of acute lymphoblastic leukemia, autoimmune disorders (e.g. Crohn’s disease and rheumatoid arthritis) and of organ transplant recipients. As inactive prodrugs, 6-mercaptopurine (6-MP), 6-thioguanine (6-TG) and azathioprine require intracellular activation, catalyzed by ...

Association between thiopurine S-methyltransferase polymorphisms and thiopurine-induced adverse drug reactions in patients with inflammatory bowel disease: a meta-analysis. [PDF]

open access: yesPLoS ONE, 2015
Thiopurine drugs are well established treatments in the management of inflammatory bowel disease (IBD), but their use is limited by significant adverse drug reactions (ADRs).

Personalization of thiopurine therapy: Current recommendations and future perspectives [PDF]

open access: yesActa Pharmaceutica
Despite great therapeutic advances in the field of biologics, small synthetic molecules such as thiopurines, including azathioprine, mercaptopurine, and thioguanine, remain an important therapeutic pillar in the treatment of inflammatory bowel disease ...

The Effectiveness of Measuring Thiopurine Metabolites in the Treatment of Autoimmune Hepatitis Patients

open access: yesThe Turkish Journal of Gastroenterology
Background/Aims: The thiopurine drugs—azathioprine and mercaptopurine—are purine antimetabolites used for the treatment of autoimmune hepatitis. These drugs undergo metabolism through genetically determined pathways, which influences their effectiveness ...

Thiopurine Metabolism in the Era of Combotherapy [PDF]

open access: yesInflammatory Bowel Diseases, 2016
6-thioguanine nucleotides levels are associated with clinical remission in patients with inflammatory bowel disease (IBD) on thiopurine monotherapy. Recently, few studies investigated the interaction between thiopurine metabolism and anti-tumor necrosis factor therapy among patients with IBD on combotherapy.

No Induction of Thiopurine Methyltransferase During Thiopurine Treatment in Inflammatory Bowel Disease

open access: yesNucleosides, Nucleotides and Nucleic Acids, 2006
The aim of this study was to follow, during standardized initiation of thiopurine treatment, thiopurine methyltransferase (TPMT) gene expression and enzyme activity and thiopurine metabolite concentrations, and to study the role of TPMT and ITPA 94C > A polymorphisms for the development of adverse drug reactions.

The NUDIX hydrolase NUDT5 regulates thiopurine metabolism and cytotoxicity

open access: yesThe Journal of Clinical Investigation
Thiopurines are anticancer agents used for the treatment of leukemia and autoimmune diseases. These purine analogs are characterized by a narrow therapeutic index because of the risk of myelosuppression.

Thiopurine methyltransferase phenotyping and genotyping in clinical practice preferred access arrangement [PDF]

open access: yes, 2010
Thiopurine methyltransferase (TPMT) metabolises the widely prescribed thiopurine drugs. The activity of this enzyme varies between individuals and this can influence treatment success.

The Thiopurine Tale: An Unexpected Journey [PDF]

open access: yesJournal of Crohn's and Colitis, 2022
Abstract Exactly 70 years ago [1951] mercaptopurine was discovered by Gertrude Elion as a novel treatment option for acute leukaemia. A total of three thiopurines (also thioguanine [1950] and azathioprine [1957]) were developed over time.
