It is a metabolite of 3'-deoxy-3',4'-didehydro-CTP. It has a role as an antiviral agent, a human blood serum metabolite, a protein synthesis inhibitor and an EC 2.7.7.48 (RNA-directed RNA polymerase) inhibitor. It is a pyrimidone and a pyrimidine 3'-deoxyribonucleoside. It is functionally related to a cytidine."}]
