distorted octahedral geometry. The interactions of the complexes with calf thymus DNA (CT-DNA) have been investigated by UV–vis absorption, fluorescence emission, and circular dichroism spectroscopy and viscosity measurements. Furthermore, DNA cleavage mechanism shows that the complexes may be capable to promote DNA cleavage through oxidative DNA damage pathway, which is indicative of the involvement
摘要 三种双核酚盐配合物[Ni2(L1)2(OAc)](BPh4)·DMF(1)、[Ni2(L2)2(OAc)](BPh4)(2)和[Ni2(L3)2( OAc)](OH)·3H2O (3),其中 L1 = 2-[双-(2-羟基-乙基)-氨基]-甲基}-4-甲基-苯酚,L2 = 2-[双-( 2-羟基-乙基)-氨基]-甲基}-4-甲氧基-苯酚,L3 = 2-[双-(2-羟基-乙基)-氨基]-甲基}-4-叔丁基-苯酚) , 已合成。单晶衍射表明所有金属原子都处于扭曲的八面体几何结构中。复合物与小牛胸腺 DNA (CT-DNA) 的相互作用已通过 UV-vis 吸收、荧光发射、圆二色光谱和粘度测量进行了研究。此外,DNA 切割机制表明复合物可能能够通过氧化 DNA 损伤途径促进 DNA 切割,这表明羟基自由基的参与,裂解过程中的单线态氧或类单线态氧实体。对 Hela 和 MCF-7 癌细

O–H⋯O hydrogen bonding interactions. Spectroscopic data of all the complexes are consistent with their molecular structures. In the cyclic voltammograms, the redox-active complexes display a quasi-reversible to irreversible metal centred reduction with the cathodic peak potential in the range −0.92 to −1.12 V (versus Ag/AgCl). All the complexes have been evaluated for their catalytic activities in oxidative
