The preparation of a series of carbocyclic exo-amino nucleosides from selected primary aromatic amines in both the C1′ α- and β-epimeric form as well as the corresponding building blocks for DNA synthesis is described. These nucleosides were incorporated into oligodeoxynucleotides and their base-pairing properties with natural bases and, in part, with themselves investigated. The results obtained confirm
描述了由C1'α-和β-表异构体形式的选定伯芳族胺制备一系列碳环外氨基氨基酸核苷以及用于DNA合成的相应结构单元。将这些核苷掺入寡脱氧核苷酸中,并与天然碱基进行碱基配对,并部分进行了研究。获得的结果证实,这种核苷类似物与DNA双链体中的天然核苷酸进行特异性相互作用。另外,它们可以形成匹配或超过Watson-Crick碱基对稳定性的自我对。因此,碳环外在设计新的碱基对时,可以考虑使用-氨基核苷来扩展遗传字母或在生物技术中的其他应用。 1引言 2条合成路线 2.1碳环外-氨基核苷和结构单元的合成 2.2寡核苷酸的合成 3寡核苷酸的配对特性 4讨论与结论 核苷-寡核苷酸-核碱基-分子识别-药物化学
