for 6-ThioguanineDescription

After incorporation into DNA, it disrupts cytosine methylation by DNA methyltransferases in vitro and acts as a DNA demethylating agent in vivo (ref 1). It reactivates epigenetically silenced genes in acute lymphoblastic leukemia cells by facilitating proteasome-mediated degradation of DNA methyltransferase (DNMT1) (ref 2). Incorporates into DNA and induces double-strand breaks which destabilize DNA structure resulting in cytotoxicity (ref 3). Selectively kills BRCA2-defective tumors and overcomes PARP inhibitor resistance in xenograft model (ref 4). Anti-cancer and immunosuppressive activity.
