bis(S-Acyl-2-thioethyl)esters of 2',3'-Dideoxyadenosine 5'-Monophosphate Are Potent Anti-HIV Agents in Cell Culture
摘要:
It is shown that ddA bis(SATE)phosphotriesters have potent anti-HIV activity in cell culture. Thus, compared with the parent nucleoside, a decrease of 3 or 4 orders of magnitude was observed in the EC(50) values for the bis(S-acetyl-2-thioethyl)phosphotriester derivative, which makes this compound as active as AZT.

The synthesis, pharmacokinetic data and biological evaluation of a series of phosphotriesters containing S-acyl-2-thioethyl groups as enzyme-labile phosphate protecting groups and AZT as a model are described. A comparison of pharmacokinetic data and ''in vitro'' experiments show that such bioreversible phosphotriesters of AZT are able to cross cell membranes and deliver the corresponding nucleoside monophosphate inside the cell. Moreover, kinetic data show that modification of the protecting groups can allow to modulate both the extracellular stability of the parent compond and the delivery of nucleoside monophosphate inside the cell.

The synthesis, in vitro anti-HIV-1 activity, and decomposition pathways of several mononucleoside phosphotriester derivatives of 3'-azido-2',3'-dideoxythymidine (AZT) incorporating a new kind of carboxylate esterase-labile transient phosphate-protecting group, namely, S-acyl-2-thioethyl, are reported. All the described compounds showed marked antiviral activity in thymidine kinase-deficient CEM cells
