Pharmacogenetics of thiopurine therapy: from thiopurine S-methyltransferase to S-adenosylmethionine [PDF]

BMC Pharmacology, 2009
Background The efficiency and safety of the thiopurine therapy rely on the concentration of patient’s cytotoxic thioguanine nucleotides (TGN), which in turn depend on the deactivation of thiopurine drugs by thiopurine S-methyltransferase (TPMT). The activity of TPMT largely depends on the presence of genetic polymorphisms. Determination of mutations in

Cancer Biomarker Test Utilization and Reimbursement in Australia: A National Analysis of Medicare Data

Clinical and Translational Science, Volume 19, Issue 5, May 2026.
ABSTRACT Biomarker testing plays a critical role in precision oncology by guiding targeted therapy selection. In Australia, public reimbursement for somatic tumor biomarker tests has expanded over the past decade, yet national data on utilization patterns, equity of access, and public expenditure remain limited. We identified all cancer biomarker tests

Model‐Based Strategy for 6‐Mercaptopurine Treatment in Acute Lymphoblastic Leukemia Maintenance Phase: Prediction of 6‐TGN and 6‐MMP Concentrations to Optimize Treatment

Pediatric Blood &Cancer, Volume 73, Issue 4, April 2026.
ABSTRACT Introduction Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer. The pro‐drug 6‐mercaptopurine (6‐MP), essential during maintenance, is converted into active 6‐thioguanine (6‐TGN) and toxic 6‐methylmercaptopurine (6‐MMP) metabolites, resulting in marked variability in efficacy and toxicity.

Tricyclic Analogs of Thioguanine as Photosensitizers of Reactive Oxygen Species-Induced DNA and RNA Damage [PDF]

Biomolecules
Analogs of tricyclic thiopurine nucleosides combine structural features of endogenous DNA adducts with efficient photosensitizing chromophores, making them valuable models for studying nucleic acid damage induced by reactive oxygen species (ROS). In this
