Definition:An organic heterotricyclic compound resulting from the formal condensation of the oxo group of cytidine to the 2' position with loss of water to give the corresponding cyclic ether. A prodrug, it is metabolised to the antineoplastic agent cytarabine, so is used to maintain a more constant antineoplastic action.
