Canadian Journal of Gastroenterology, 2008 BACKGROUND: At least one-third of patients with inflammatory bowel disease do not respond or are intolerant to therapy with 6-mercaptopurine (6-MP). A subgroup fails to attain optimal levels of 6-thioguanine nucleotide (6-TGN) and instead shunts to 6 ...

Imaging of Abdominal Complications in Children With Acute Lymphoblastic Leukaemia
Journal of Medical Imaging and Radiation Oncology, EarlyView.ABSTRACT Acute lymphoblastic leukaemia (ALL) is the most common paediatric malignancy and remains one of the most common causes of cancer‐related death in children and adolescents. Five‐year overall survival rates now exceed 90% with current multidrug chemotherapeutic regimens. This improvement, coupled with the toxicity of chemotherapy, has led to the

Assay of 6‐thioguanine in human plasma. [PDF]
British Journal of Clinical Pharmacology, 1980 1. A fluorimetric method has been developed for measuring therapeutic concentrations of 6‐thioguanine in human plasma. The drug was measured as an oxidized derivative, guanine 6‐sulphonate. 2. 6‐thioguanine was extracted from plasma by a novel procedure which isolated the drug from an interfering plasma components. This method involved the formation of

Direct evidence of singlet molecular oxygen [O2 (1Δg)] production from UVA excited 6‐thioguanine
Photochemistry and Photobiology, EarlyView.6‐Thioguanine (6‐TGua) is incorporated into DNA as a purine analogue, inhibiting cell replication. Patients treated with 6‐TGua are more prone to developing skin cancer due to the photoexcitation of 6‐TGua by UVA radiation (as illustrated in the Jablonski diagram). Upon exposure to UVA, the excited 6‐TGua generates 1O2.

Cancer Reports, Volume 9, Issue 2, February 2026.ABSTRACT Background Azathioprine (AZA) is a purine antimetabolite immunosuppressant that prevents the body from rejecting transplanted organs and is used in organ transplant recipients (OTRs). This study aimed to conduct a meta‐analysis to determine whether AZA usage has an increased risk of skin cancer in OTRs.

PLoS ONE, 2021 BackgroundLarge inter-individual variations in drug metabolism pose a challenge in determining 6-mercaptopurine (6MP) doses. As the last product of 6MP metabolism, DNA-thioguanine nucleotide (DNA-TGN) could reflect the efficacy of 6MP, especially in ...

Signalling cell cycle arrest and cell death through the MMR System [PDF]
, 2006 Loss of DNA mismatch repair (MMR) in mammalian cells, as well as having a causative role in cancer, has been linked to resistance to certain DNA damaging agents including clinically important cytotoxic chemotherapeutics.
