unstable DNA lesions enables accurate study of polymerase bypass. We report the design and synthesis of N7-hydroxyethyl-9-deaza-2′-deoxyguanosine and N7-oxoethyl-9-deaza-2′-deoxyguanosine as the analogues of N7-hydroxyethyl-2′-deoxyguanosine and N7-oxoethyl-2′-deoxyguanosine, respectively. We also developed the synthesis of these two nucleosides whose N7 side chains are protected by TBS for the convenience
稳定的DNA损伤的
化学稳定类似物的开发使得能够精确研究聚合酶旁路。我们报告设计和合成的N 7-羟乙基-9-脱氮-
2'-脱氧鸟苷和N 7-氧乙基-9-脱氮-
2'-脱氧鸟苷作为N 7-羟乙基-
2'-脱氧鸟苷和N 7的类似物-氧代乙基-
2'-脱氧鸟苷。我们还开发了这两个核苷的合成方法,它们的N 7侧链受TBS保护,以方便转换为亚
磷酰胺。
