novel nucleoside analogues for the formation of triplex DNA containing pyrimidine–purine inversion sites has been a challenging field. In this paper, we describe the design and synthesis of non-natural nucleoside analogues, N-substituted-2′-deoxy-5-methylisocytidine derivatives, and their evaluation for triplex formation. It has been shown that N-(guanidinoethyl)-2′-deoxy-5-methylisocytidine exhibits
用于形成含嘧啶-嘌呤倒位位点的三链体DNA的新型核苷类似物的开发一直是一个充满挑战的领域。在本文中,我们描述了非天然核苷类似物N-取代的2'-脱氧-5-甲基异胞苷衍生物的设计与合成,以及它们对三链体形成的评估。已经显示出N-(胍基乙基)-2'-脱氧-5-甲基异胞苷显示出对CG中断位点的选择性识别并增强了反平行三链体的形成。
