The interactions between these complexes and calf thymus DNA (CT-DNA) were studied by electronic absorption and viscosity measurements. The activities of these compounds against oxidative DNA cleavage were examined by agarose gel electrophoresis. Cu(II) and Ni(II) complexes can wind DNA strands through groove interactions and promote strand breakage of the plasmid pmCherry under oxidative stress conditions. Moreover, all the complexes could interact more strongly with DNA than could with the free ligands. Finally, the antibacterial activities of the ligands and their complexes were determined by 体外对革兰氏阳性细菌菌株测试( 金黄色葡萄球菌ATCC 25923, 单增李斯特菌ATCC 19115,和 蜡样芽孢杆菌ATCC 10876)和革兰氏阴性细菌菌株( 大肠杆菌ATCC 25922, 鼠伤寒沙门氏菌ATCC 14028,和 肺炎克雷伯菌使用微量肉汤稀释法ATCC BAA-2146)。金属配合物表现出比对一些微生物的前体配体更大的抗微生物活性。SN - 1565-3633 UR - https://doi.org/10.1155/2019/3520837 DO - 10.1155 /三百五十二万○八百三十七分之二千○一十九JF - 生物无机化学及应用PB - Hindawi出版KW - ER -
