title: Effects of aryl substituents on the anti-HIV activity of the arylphosphoramidate derivatives of stavudine.
abstract: We compared the anti-HIV activity of 13 phenyl phosphate derivatives of stavudine (2',3'-didehydro-2',3'-dideoxythymidine/d4T) by examining their ability to inhibit HIV-1 replication in human peripheral blood mononuclear cells. Our results show that the introduction of electron-withdrawing substituents enhances the activity of these phosphoramidate derivatives. The rate of chemical hydrolysis under alkaline conditions (but not the lipophilicity) predicted the potency of the compounds.
