Three ternary copper(II) complexes [Cu(L1)(phen)] (1), [Cu(L2)(phen)] (2), and [Cu(L3)(phen)]·2H2O (3) (L1 = 4-fluoro-2-(picolinamido)benzoic acid, L2 = 4,5-difluoro-2-(picolinamido)benzoic acid, L3 = 4,5-difluoro-2-((2-hydroxybenzylidene)amino)benzoic acid, phen = 1,10-phenanthroline) have been synthesized and characterized by physicochemical and spectroscopic methods. In addition, X-ray crystallography
三种三元铜 (II) 配合物 [Cu(L1)(phen)] (1)、[Cu(L2)(phen)] (2) 和 [Cu(L3)(phen)]·2H2O (3) (L1 = 4-氟-2-(吡啶甲酰胺基)苯甲酸,L2 = 4,5-二氟-2-(吡啶甲酰胺基)苯甲酸,L3 = 4,5-二氟-2-((2-羟基亚苄基)氨基)苯甲酸, phen = 1,10-菲咯啉)已通过物理化学和光谱方法合成和表征。此外,X 射线晶体学表明,每个配合物中的 Cu 原子是五配位的,采用扭曲的四方锥体或三角双锥体几何结构。通过紫外吸收、荧光光谱和粘度测量研究了复合物与小牛胸腺 DNA 的相互作用。此外,还筛选了复合物对 A549(人肺癌细胞)的体外细胞毒性,Jurkat(人 T 淋巴细胞细胞系)和 HepG-2(人肝肝癌细胞);这些实验表明复合物 3 表现出最有效的细胞毒性(IC50 = 1.224–7.099 µM)。抗菌研究表明,复合物
