3-Deazaneplanocin A (DZNep, C-c3Ado) is a drug which acts as both a S-adenosylhomocysteine synthesis inhibitor and also a histone methyltransferase EZH2 inhibitor. Studies have shown that it has in vitro against a variety of different tumor cell lines.[1][2][3][4][5]

In studies on mice, 3-deazaneplanocin A was also found to be effective for the treatment of Ebola virus disease,[6] apparently interfering with the Ebola viruses ability to block interferon production which usually allows it to evade immune responses.[7][8]
