An Inhibitor of DNA Methylation

The cytidine analogs 5-aza-2'-deoxycytidine and 5-azacytidine [A2033] are inhibitors of DNA methyltransferases (DNMTs) which catalyze the transfer of a methyl group to DNA. DNA methylation is an epigenetic factor and plays an important role in regulating gene expression. 5-Azacytidine and 5-aza-2'-deoxycytidine are the currently most advanced agents for epigenetic cancer therapies.
