. are as defined herein. These compounds are useful as substrates for DNA/RNA polymerases, and as anti-viral agents in particular against HIV-1.
phosph(on)ate amino acid phosphoramidate analogues of deoxynucleotides were synthesized as potential substrates for HIV-1 reverse transcriptase. Taurine, L-cysteic acid, 3-phosphono-L-alanine, O-sulfonato-L-serine, and O-phospho-L-serine were investigated as leaving groups in an enzyme catalyzed DNA synthesis protocol. Among these analogues, the phosphonate congener performed best and 3-phosphono-L-alanine
