A family of terpyridine metallo-organic complexes has been designed and its recognition properties of G-quadruplex-DNA investigated. The series combines easy synthetic access and good affinity–selectivity ratio for quadruplex-DNA. Our study also highlights that the geometry of the metal center strongly governs the ability of the compounds to discriminate quadruplex from duplex-DNA.
设计了一系列三联吡啶金属有机配合物,并研究了其对 G-四链体-DNA 的识别特性。该系列结合了易于合成的方法和良好的四链体 DNA 亲和力-选择性比。我们的研究还强调,金属中心的几何形状很大程度上决定了化合物区分四链体和双链体 DNA 的能力。
