Zebularine is a cell-permeable chemically stable cytidine analog and DNA methylation inhibitor which acts by forming a covalent complex with DNMT. It displays antiangiogenic activity and markedly inhibits vessel formation in different tumor models. It reactivates silenced E-cadherin and potentiates the effects of other epigenetic therapeutics such as vorinistat. Induces differentiation of mesenchymal cells into cardiomyocytes. Inhibits cytidine deaminase (CDD).
