[An orally bioavailable pyrimidine analog with potential antineoplastic activity. Sapacitabine is hydrolyzed by amidases to the deoxycytosine analog CNDAC (2'-Cyano-2'-deoxyarabinofuranosylcytosine), which is then phosphorylated into its active triphosphate form. As an analog of deoxycytidine triphosphate, CNDAC triphosphate molecules get incorporated into DNA strands during replication, thereby leading to single-stranded DNA breaks caused by beta-elimination in fidelity check point. As a result, this agent induces cell cycle arrest in the G2 phase and subsequently triggers apoptosis. ( NCI )]
