Application

6-Thioguanine has been used:
  • to induce autophagy and apoptosis in colorectal cancer cell lines HCT116[1]
  • as a selection marker in the mutation and survival assay in chinese hamster lung fibroblasts culture V79[2]
  • as a selection marker in clonogenic Lung metastasis assay of 4T1-luc cells[3]

Biochem/physiol Actions

Antimetabolite used in the treatment of leukemias. Competes with hypoxanthine and guanine for the enzyme hypoxanthine-guanine phosphoribosyltransferase, which catalzyes a critical step in the generation of purine nucleotides.
Ribosylated and phosphorylated by the same pathway as natural purine bases; as the nucleotide, inhibits a variety of cellular processes involved in nucleic acid synthesis. Has a long history as an effective treatment of leukemia.

General description

6-Thioguanine is a variant of guanine with hydrogen bonding at the N-7 of the purine ring. Its association with cytosine alters the dimension of the base stacking.[4] 6-Thioguanine usage in treating inflammatory bowel disease (IBD) contributes to nodular regenerative hyperplasia (NRH) in the liver.[5]
