摘要
以氯化铜、1-苯基-3-甲基-4-苯甲酰基-5-吡唑啉酮和2,6-吡啶二羧酸为原料,制备了一个新型的三元配合物,通过元素分析、红外光谱、紫外光谱、X射线粉末衍射、热重-差热分析、光电子能谱分析及TEM等手段对配合物进行了表征,确定了配合物的化学组成可能是Na[Cu(PMBP)(PDA)].抗菌实验结果表明,配合物对大肠杆菌、金黄色葡萄球菌具一定的抑制作用.采用紫外光谱法和荧光光谱法初步研究了配合物与CT-DNA的作用方式,结果表明:配合物可能是以插入模式与DNA结合的.
A new solid ternary complex of copper with 1 - phenyl-3-methyl-4-acetyl - pyrazolone - 5 and 2,6-pyridinecarboxylic acid Na[ Cu(PMBP) (PDA] has been synthesized and characterized by elemental analysis, FT- IR, UV -Vis, XRD ,TG- DTA, and XPS. The antibacterial test indicated that the complex exhibited moderate antibacterial ability against Escherichia coli and- Staphylococcus aureus. The interactions of the complex with calf thymus DNA ( CT DNA ) was investigated by employing flores- cence spectroscopic studies and ultraviolet spectrum speetrom etries. The results indicated that the complex can intercalate be- tween DNA base pairs.
