5,6-dihydro-5-azacytidine (DHAC) is a hydrolytically stable congener of 5-azacytidine. It exerts cytostatic action in vitro. DHAC induces DNA hypomethylation. DHAC inhibits DNA methyltransferase, thereby interfering with abnormal DNA methylation patterns that are associated with genetic instability in some tumor cells. Inhibition of this enzyme may restore expression of tumor-suppressor genes and result in antitumor activity. It was in phase II studies for the treatment of several cancers such as malignant melanoma, mesothelioma and others.
