Zusammenfassung
4′-Acylated thymidines represent a new class of DNA chain terminators, since they have been shown to act as post-incorporation chain-terminating nucleotides despite the presence of a free 3′-hydroxyl group. Here, we describe the action of the 4′-acetyl- (MeTTP) and 4′-propanoylthymidine 5′-triphosphate (EtTTP) on HIV-1 reverse transcriptase in RNA- and DNA-dependent DNA synthesis and on DNA synthesis catalyzed by the cellular DNA polymerases α, β, δ and ε. MeTTP exhibits a high selectivity towards HIV-1 reverse transcriptase. By the use of the bulkier propanoyl group as the 4′-substituent of the nucleoside 5′-triphosphate, selectivity towards HIV-1 reverse transcriptase could be increased without affecting substrate efficiency. Thus, 4′-modifications may serve as a tool to increase selectivity towards HIV-1 reverse transcriptase.
