Applications

Anticancer agent; Downregulates DNMT1

Functions

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

Application Procedures

First dissolved in DMF (up to 1.5 mg/ml with warming), then diluted to aqueous buffer. Solutions in DMF may be stored at -20°C for up to 1 month.

Research use only.
