Abstract. Isosteric triphosphonate derivatives of 2′,3′-dideoxy-2′,3′-didehydroadenosine and 3′-deoxy-2′,3′-didehydrothymidine and their β,γ-substituted analogues were synthesized. Their substrate properties toward a number of reverse transcriptases of the human immunodeficiency and avian myeloblastosis viruses, human DNA polymerases α and β, and the Klenow fragment of Escherichia coli DNA polymerase I were studied.
Key words: isosteric analogues of dNTP; substrate properties; human DNA polymerases; HIV and avian myeloblastosis reverse transcriptases; Klenow fragment
