3′-Deoxy CTP trisodium

3?-Deoxy CTP trisodium is the sodium salt form of 3?-Deoxy CTP. This compound is a nucleotide analog known as a chain terminator. By lacking a 3?-hydroxyl group, it causes chain termination and inhibits the RNA synthesis activity of the HCV non-structural protein (NS5B) polymerase, thereby blocking viral replication. 3?-Deoxy CTP trisodium is utilized in the study of chain termination mechanisms of HCV polymerase and the development of antiviral drugs.
