2′-bipyridine, and 6-(4-chlorophenyl)-4-p-tolyl-2,2′-bipyridine), have been synthesized and characterized. Interaction of palladium complexes with DNA has been investigated by electronic absorption spectra, viscosity measurements and DNA melting temperature techniques. The metal complex-DNA interaction produced hypochromism and bathochromism, suggesting intercalative binding. Viscosity data support the
一系列方形平面单核钯 (II) 配合物,[Pd(L n )(OMe)2](其中 L n = 4-(4-氯苯基)-6-苯基-2,2'-联吡啶,4,6 -双(4-氯苯基)-2,2'-联吡啶、4-(4-溴苯基)-6-(4-氯苯基)-2,2'-联吡啶和6-(4-氯苯基)-4-p -tolyl-2,2'-bipyridine),已被合成和表征。钯配合物与 DNA 的相互作用已通过电子吸收光谱、粘度测量和 DNA 熔解温度技术进行了研究。金属络合物-DNA 相互作用产生低色度和红度色,表明嵌入结合。粘度数据支持结合的插层模式。钯 (II) 复合物促进质粒 pUC19 DNA 从超螺旋形式切割为开环形式。还评估了复合物对五种病原菌的抗菌活性。抗菌测试结果表明,与配体和金属盐相比,所有化合物对革兰氏 (-ve) 和革兰 (+ve) 细菌物种均具有良好的抗菌活性。
