ABSTRACT:
Aryl phosphate derivatives of d4T with para-bromo substitution on the aryl group show markedly increased potency as anti-HIV agents without undesirable levels of cytotoxic activity. In particular, these derivatives are potent inhibitors of HIV reverse transcriptase. In a preferred aspect of the present invention, the phosphorus of the aryl phosphate group is further substituted with an amino acid residue that may be esterified or substituted, such as a methoxy alaninyl group.
