A new synthesis of the nucleoside analogue 3-deaza-2′-deoxycytidine is described. The N3-nitrogen of dC is involved in the central hydrogen bond of a dG-dC base pair. The relative importance of hydrogen bonding as a controlling factor in the activity of DNA polymerase is examined by studying both duplex stability and template effects for this dc3C nucleoside. Duplexes containing dG-dc3C base pairs
描述了核苷类似物3-deaza-2'-脱氧胞苷的新合成。dC的N 3-氮参与dG-dC碱基对的中心氢键。通过研究该dc 3 C核苷的双链体稳定性和模板效应,研究了氢键作为控制DNA聚合酶活性的控制因素的相对重要性。含有dG-dc 3 C碱基对的双链体极不稳定,而发现含有类似核苷的模板仅掺入了互补的dG三磷酸酯,这与含有天然2'-脱氧胞苷的模板的观察结果相似。
