ABSTRACT The synthesis and characterization of novel acyclic and cyclic pyridone-based nucleosides and nucleotides is described. In total, seven nucleosides and four nucleotides were synthesized. None of the tested nucleosides showed inhibitory properties against Klenow exo- polymerase and M.MuLV and HIV-1 reverse transcriptases. The nucleotides containing 4-chloro- and 4-bromo-2-pyridone as a nucleobase
摘要描述了新型的基于无环和环状
吡啶酮的核苷和核苷酸的合成和表征。总共合成了七个核苷和四个核苷酸。所测试的核苷均未显示出对Klenow外切聚合酶以及M.MuLV和HIV-1逆转录酶的抑制特性。包含4-
氯和4-
溴-2-
吡啶酮作为核碱基的核苷酸被Klenow片段接受,但是以保真度和延伸效率为代价。
