We report herein an efficient synthesis of new nucleosides N1, N2, and N3 as extended guanine analogues, derived from aminobenzimidazole and thymine or 5-substituted uracil. These nucleosides were devised for the recognition of an A·T inverted base pair by three hydrogen bonds, in triple helix-based technology.
我们在此报告了一种新的核苷酸N1,N2和N3的有效合成方法,它们是扩展的鸟嘌呤类似物,衍生自氨基苯并咪唑和胸腺嘧啶或5-取代的尿嘧啶。这些核苷被设计用于在基于三螺旋的技术中通过三个氢键识别A·T反向碱基对。
