Cyclocytidine (also known as Ancitabine) is the prodrug of cytarabine, which is structurally similar to human deoxycytidine to be incorporated into human DNA and then kills the cell. Cyclocytidine was introduced as an antineoplastic agent for the treatment of lymphatic leukemia, sinus acceleration and an increase in systemic blood pressure. Cyclocytidine in combination with amsacrine were effective retrieval therapy for pediatric patients with acute nonlymphoblastic leukemia who were in relapse or unresponsive to frontline therapy.
