- W2346126896 abstract "合成了一系列含有平面配体的Cu(Ⅱ)多吡啶配合物[Cu(IP)2]2+、[Cu(PIP)2]2+、[Cu(DPPZ)2]2+和[Cu(HPIP)2]2+,用吸收光谱、CD光谱和粘度等方法研究了这些配合物与小牛胸腺DNA的作用.结果表明配体上的取代基及配体的平面性对这些四面体配合物与DNA的结合强弱产生一定的影响.[Cu(DPPZ)2]2+与DNA的结合较强,而[Cu(HPIP)2]2+与DNA的结合较弱.CD光谱显示配合物[Cu(DPPZ)2]2+、[Cu(PIP)2]2+和[Cu(HPIP)2]2+的加入会导致DNA的CD光谱减弱.而[Cu(IP)2]2+的加入则会使DNA的CD光谱增强.同时,[Cu(IP2)2]2+与DNA结合后,还会引起一定程度的DNA构型转换,即DNA从B型转换成Z型." @default.
