WebAnswer (1 of 2): You should change your question to “as hard as removing a single methyl group”, not “as simple”. As far as I’m aware that’s not an easy thing to achieve at all. Basically, you should ask “how do you demethylate secondary amines”. The process for removing the N-methyl and the alph... Demethylating agents are chemical substances that can inhibit methylation, resulting in the expression of the previously hypermethylated silenced genes (see Methylation#Cancer for more detail). Cytidine analogs such as 5-azacytidine (azacitidine) and 5-azadeoxycytidine (decitabine) are the most commonly used demethylating agents. They work by inhibiting DNA methyltransferases.

WebThe DNA demethylating agents inhibit DNA methyltransferase enzymes, causing reduced overall levels of DNA methylation. There are two classes of DNA demethylating agents: nucleoside DNMT inhibitors and nonnucleoside DNMT inhibitors (Table 12.1 ). 1. Nucleoside inhibitors of DNA methyltransferases. WebDrugs that demethylate DNA would presumably activate expression of demethylated genes. Cancer growth and progression may be inhibited if these drugs are able to turn on expression of tumor suppressor genes that had been silenced by DNA methylation.
