The synthesis, antiviral activity, and stability study of phosphotriester derivatives of 3'-azido-2',3'-dideoxythymidine (AZT) bearing modified l-tyrosinyl residues are reported. These compounds were obtained via phosphoramidite (P(III)) chemistry from the appropriate aryl precursors. All the derivatives were evaluated for their in vitro anti-HIV activity, and they appeared to be potent inhibitors of HIV-1 replication in various cell culture experiments, with EC(50) values between the micro- and nanomolar range, especially in thymidine kinase deficient (TK(-)) cells, showing their ability to act as mononucleotide prodrugs. The proposed decomposition process of these mixed mononucleoside aryl phosphotriesters successively involves an esterase and a phosphodiesterase hydrolysis.

D015215 Zidovudine A dideoxynucleoside compound in which the 3'-hydroxy group on the sugar moiety has been replaced by an azido group. 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, acting as a chain-terminator of viral DNA during reverse transcription. It improves immunologic function, partially reverses the HIV-induced neurological dysfunction, and improves certain other clinical abnormalities associated with AIDS. Its principal toxic effect is dose-dependent suppression of bone marrow, resulting in anemia and leukopenia.
