Abstract/OtherAbstract:
A series of hydrophobic, water soluble and non-toxic amino acid phosphoramidate monoesters of dideoxyadenosine (ddA) and 3'-azido-3'-deoxythymidine were shown to inhibit the replication of HIV-1 in human peripheral blood mononuclear cells (PBMC) from two donors. The tryptophan methyl ester phosphoramidates of AZT and ddA were equally potent (EC50S = 0.3-0.4 microM), while the phenyl methyl ester of ddA was 40- to 100- fold more potent than the AZT derivatives. The alaninyl methyl ester of AZT was found to be 70- fold more potent than the ddA derivative. The methyl amide derivatives were found to be 5-20 fold less active than the methyl esters for the ddA series, while for AZT the derivatives were found to be of similar potency or 60- to 166- fold more potent than the methylesters.
