the formation of Ru(II) complexes of the type [RuCl2(η6-benzene)L] (L = monodentate aroylthiourea ligand). The complexes were well characterized using UV-Visible, FT-IR, NMR and mass spectroscopic techniques. Single crystal X-ray diffraction confirmed the monodentate coordination of the ligand through a sulfur atom. The interaction of the Ru(II) complexes with calf thymus DNA (CT DNA) was investigated
的反应将[RuCl 2(η 6 -苯)] 2与aroylthiourea导致的Ru(形成II)的类型的复合物将[RuCl 2(η 6 -苯)L](L =单齿aroylthiourea配体)。使用紫外可见光谱,傅立叶变换红外光谱,核磁共振和质谱技术对复合物进行了很好的表征。单晶X射线衍射证实了配体通过硫原子的单齿配位。Ru(II牛小胸腺DNA(CT DNA)的复合物使用紫外可见和荧光光谱法进行了研究,并进行了粘度测量。使用紫外可见和荧光实验探索了该复合物与牛血清白蛋白(BSA)的结合能力。结果表明,该复合物以明显的结合常数与生物分子相互作用。凝胶电泳技术用于证明超螺旋DNA展开为其刻痕形式。针对一组癌细胞系,例如HepG2,A549,MCF7和SKOV3,筛选了Ru(II)配合物的细胞毒性。配合物1,2和3在31.25浓度表现出中等活性微克毫升-1对抗HepG2细胞。复合物1和3在62.5μgmL
