5-Azacytidine is an inhibitor of DNA-methyltransferases that causes DNA-demethylation or hemi-demethylation. It regulates gene activation and silencing by creating openings that allow transcription factors to bind to DNA and thus for instance to reactivate tumor suppressor genes. 5-Azacytidine is a prodrug, which needs to be phosphorylated by cellular cytidine kinases. Resulting 5-Aza-dCTP is incorporated into DNA and traps the DNA methyltransferase in the progressing fork. 5-Azacytidine is used in treatment of several cancer diseases. IC50 = 2.4 to 2.6 μM for in vitro anti-myeloma activity (myelodysplastic syndrome) and 0.4 μM for inhibiting proliferation of various cancer cell lines.
