<unk>  is an analog of pyrimidine. It is a derivative of the naturally existing deoxycytidine, made by replacing the hydroxyl group in position 3' with a hydrogen. It is phosphorylated in T cells and other HIV target cells into its active triphosphate form,<unk> TP. This active metabolite works as a substrate for HIV reverse transcriptase, and also by incorporation into the viral DNA, hence terminating the chain elongation due to the missing hydroxyl group. Since<unk>  is a reverse transcriptase inhibitor it possesses activity only against retroviruses.
