Nucleosides Nucleotides Nucleic Acids. 2003 May-Aug;22(5-8):907-9. doi: 10.1081/NCN-120022683.

Abstract

The stability of phosphotriester derivatives of 3'-azido-2',3'-dideoxythymidine (AZT) bearing a S-pivaloyl-2-thioethyl (tBuSATE) group and various aryl residues derived from L-tyrosine was evaluated in biological media. The results demonstrate that such compounds give rise to intracellular delivery of the parent mononucleotide through esterase and phosphodiesterase hydrolytic steps, successively.
