Three novel transition metal complexes [ML2(phen)]·H2O (M= Mn, Co, Zn; HL= C10H7O2NSe, 2-phenyl-4-selenazole carboxylic acid, phen= 1,10-phenanthroline) 1∼3 were synthesized and characterized by elemental analysis, IR spectra. Their crystal structures were deterimined by single-crystal X-ray diffraction method. The antibacterial activities of the complexes against five species of bacteria, Escherichia coli (E. coli), Staphylococcus epidermidis (S. epidermidis), Staphylococcus aureus (S. aureus), Acinetobacter baumanii (A. baumanii) and Streptococcus viridans (S. viridans), were tested respectively. The anticancer activities of the complexes against human pancreatic cancer line PANC-28 and human hepatocarcinoma line HuH7 were also studied. The interactions between the complexes and DNA were studied by ethidium bromide (EB) fluorescent probe.
合成了三种新型过渡金属配合物 [ML2(phen)]-H2O(M= Mn、Co、Zn;HL= C10H7O2NSe、2-苯基-4-硒唑羧酸,phen= 1,10-菲罗啉)1∼3,并通过元素分析和红外光谱对其进行了表征。通过单晶 X 射线衍射法确定了它们的晶体结构。分别测试了复合物对大肠杆菌(E. coli)、表皮葡萄球菌(S. epidermidis)、金黄色葡萄球菌(S. aureus)、鲍曼不动杆菌(A. baumanii)和病毒性链球菌(S. viridans)五种细菌的抗菌活性。此外,还研究了复合物对人胰腺癌细胞系 PANC-28 和人肝癌细胞系 HuH7 的抗癌活性。利用溴化乙锭(EB)荧光探针研究了复合物与 DNA 之间的相互作用。
