mononuclear copper(II) complexes with second generation fluoroquinolone drug ciprofloxacin (CFL) and some bipyridine derivatives (An) of type [Cu(CFL)(An)Cl]·2H2O. The DNA binding free energies were evaluated by studying the effect of salt concentrations on DNA binding. DNAinteractions were investigated by using DNA melting temperature studies, viscosity measurements, absorption titration, and gel electrophoresis
我们的工作重点是合成和表征中性单核铜 (II) 配合物与第二代氟喹诺酮类药物环丙沙星 (CFL) 和一些 [Cu(CFL)(An)Cl]·2H2O 型联吡啶衍生物 (An)。通过研究盐浓度对 DNA 结合的影响来评估 DNA 结合自由能。通过使用 DNA 熔解温度研究、粘度测量、吸收滴定和凝胶电泳实验来研究 DNA 相互作用。还研究了超氧化物歧化酶 (SOD) 样活性(IC50 值)和金属配合物的抗菌活性。为了验证质粒 DNA 切割的正确机制途径,在自由基清除剂的存在下进行了凝胶电泳实验。
