Description: Anticancer and immunosuppressive agent
Alternative Names: 6-TG
Chemical Name: 2-Amino-6-mercaptopurine
Purity: ≥98% (HPLC)
Biological Activity for 6-Thioguanine
6-Thioguanine is an anticancer and immunosuppressive agent often used to treat immune disorders and leukemia. Displays cytotoxic and antineoplastic properties; disrupts cytosine methylation by DNA methyltransferases after incorporation into DNA. Selectively kills BRCA2-defective tumors in a xenograft model. Also facilitates proteasome-mediated degradation of DNA (cytosine-5)-methyltransferase 1 (DNMT1). Also inhibits SARS-CoV papain-like protease (PLpro; IC50 = 5 μM for PLpro deubiquitination activity).

The effects of 6-thioguanine on growth and metabolism.

Species: Human
6-Thioguanine was incorporated into the RNA of all subcellular fractions, but to different extents and it also appears to be incorporated into a non-nucleotide fraction in the cell walk.
