Thiopurines in the Management of Crohn’s Disease: Safety and Efficacy Profile in Patients with Normal TPMT Activity—A Retrospective Study

Canadian Journal of Gastroenterology and Hepatology, 2016
Background and Aims. Thiopurines are used in the treatment of Crohn’s disease (CD) and thiopurine S-methyltransferase (TPMT) activity can guide thiopurine dosing to avoid adverse events.

Polymorphisms of the thiopurine S-methyltransferase gene among the Libyan population [PDF]

Libyan Journal of Medicine, 2015
Background: Thiopurine S-methyltransferase (TPMT) is a cytosolic enzyme that catalyses the S-methylation of 6-mercaptopurine and azathioprine. Low activity phenotypes are correlated with polymorphism in the TPMT gene.

Successful pregnancies with thiopurine-allopurinol co-therapy for inflammatory bowel disease [PDF]

, 2015
Background: Thiopurines are an effective treatment for moderate to severe inflammatory bowel disease [IBD] and can be used safely in pregnancy. Combining allopurinol with a lower dose of thiopurine can improve clinical efficacy and bypass some adverse ...

6-methylmercaptopurine-induced leukocytopenia during thiopurine therapy in inflammatory bowel disease patients [PDF]

, 2017
Background and Aim: Thiopurines have a favorable benefit–risk ratio in the treatment of inflammatory bowel disease. A feared adverse event of thiopurine therapy is myelotoxicity, mostly occurring due to toxic concentrations of the pharmacologically ...

Biocatalytic Construction of a Chemical Exchange Saturation Transfer Magnetic Resonance Imaging Nucleoside Probe: Synthesis and Evaluation of 5‐Methyl‐5,6‐Dihydrothymidine

Advanced Synthesis &Catalysis, Volume 368, Issue 1, January 2026.
Al‐Hilfi et al. present a biocatalytic strategy for synthesizing 5‐methyl‐5,6‐dihydrothymidine (5‐MDHT), a sensitive MRI contrast agent. The study demonstrates that recombinant enzyme catalysis offers an efficient, sustainable, and eco‐friendly alternative to traditional chemical synthesis for producing clinically relevant imaging probes.

Physiologically‐Based Pharmacokinetic Modeling to Support Pediatric Clinical Development: An IQ Working Group Perspective on the Current Status and Challenges

CPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 1, January 2026.
ABSTRACT Pediatric extrapolation strategies issued by health authorities have streamlined pediatric drug development and reduced the unnecessary burden of conducting pediatric clinical studies. In line with these strategies, physiologically based pharmacokinetic (PBPK) models have been utilized extensively for initial dosing regimen and sampling ...

Thiopurine-S-Methyltransferase Gene Polymorphism and Drug-related Toxicity in Children Treated for Acute Leukemia and Non-Hodgkin’s Lymphoma

Journal of Pediatric Research, 2022
Aim:Thiopurine S-methyltransferase (TPMT) is an essential enzyme in the metabolism of thiopurine drugs, and its activity may change due to different polymorphisms in the TPMT gene.
