δ-Di-carboxybutyl phosphoramidate of 2′-deoxycytidine-5′-monophosphate as substrate for DNA polymerization by HIV-1 reverse transcriptase Original Research Article

The replacement of the pyrophosphate moiety of 2′-deoxynucleoside triphosphates by non natural δ-dicarboxylic butyl amino acid allows incorporation of natural 2′-deoxycytidine into DNA using HIV-1 reverse transcriptase (RT) as enzyme. In contrast, the 3′-deoxycytidine analogue was not a substrate of the HIV-1 RT.
