magnetic susceptibility and EPR spectral data of metal complexes suggest an octahedral geometry. The bindingproperties of these complexes with calf thymus DNA (CT-DNA) have been explored using electronic absorption spectroscopy, viscosity measurement, cyclic voltammetry and differential pulse voltammetry. The DNA-binding constants for Cu(II), Ni(II), Co(II), and Zn(II) complexes are 6.14 × 105 M−1, 1.8 × 105 M−1
本工作报告了一系列具有[M(L)(phen)2 ] Cl 2(其中M = Cu(II),Ni(II),Co(II))组成的混合配体配合物的DNA结合和裂解特性。以及Zn(II)和phen作为共配体)。从其元素分析,磁化率和摩尔电导率以及IR,UV-Vis,1推导了它们的结构特征和其他特性。1 H NMR和EPR光谱研究。金属配合物的UV-Vis,磁化率和EPR光谱数据表明八面体的几何形状。使用电子吸收光谱,粘度测量,循环伏安法和差动脉冲伏安法研究了这些复合物与小牛胸腺DNA(CT-DNA)的结合特性。对Cu(II),镍(II),钴(II)和Zn(II)的DNA结合常数络合物是6.14×10 5 中号-1,1.8×10 5 中号-1,6.7×10 4 中号- 1和2.5×10 4 M -1分别。详细的分析表明,这些复合物通过嵌入结合与DNA相互作用。核酸酶活性也已通过凝胶电泳进行了研究。此
