| zalcitabine | <chemical> A dideoxynucleoside compound in which the 3'-hydroxy group on the sugar moiety has been replaced by a hydrogen. This modification prevents the formation of phosphodiester linkages which are needed for the completion of nucleic acid chains. The compound is a potent inhibitor of HIV replication at low concentrations, acting as a chain-terminator of viral DNA by binding to reverse transcriptase. Its principal toxic side effect is axonal degeneration resulting in peripheral neuropathy. Pharmacological action: anti-HIV agents, antimetabolites, reverse transcriptase inhibitors. Chemical name: Cytidine, 2',3'-dideoxy- (12 Dec 1998) |

Zalcitabine (2'-3'-dideoxycytidine, ddC), is a derivative of the naturally existing deoxycytidine, made by replacing the hydroxyl group in position 3' with a hydrogen. It is phosphorylated in the T cell into its active triphosphate form, ddCTP. This active metabolite works as a substrate for the reverse transcriptase, and also by incorporation into the viral DNA, hence terminating the chain elongation due to the missing hydroxyl group. ...

| zalcitabine |
a nucleoside analog drug that inhibits HIV replication by interfering with the reverse transcriptase enzyme. The drug is FDA-approved for the treatment of HIV disease; current practice favors use in combinations. Adverse side effects may include nausea, peripheral neuropathy, oral ulcers and pancreatitis.
