A series of mononuclear ruthenium arene complexes with thiosemicarbazone (TSC) ligands (A-type, 1–8) and their corresponding di-nuclear analogues (B-type, 9–16) were synthesized and characterized by NMR, elemental analysis and HR-ESI-mass spectrometry. The molecular structures of 1, 2, 6, 9–11 and 13–16 were determined using single-crystal X-ray diffraction analysis. The Gibbs free energy of the two
合成了一系列具有硫代半碳zone(TSC)配体的单核钌芳烃配合物(A型,1-8)及其相应的双核类似物(B型,9-16),并通过NMR,元素分析和HR- ESI-质谱。的分子结构1,2,6,9-11和13-16中使用确定的单晶X射线衍射分析。使用密度泛函理论(DFT)计算研究了两种类型的复合物(1和9)的两个实例的吉布斯自由能以及它们单晶的键合顺序。进一步评估这些化合物的化合物对CNE-2人鼻咽癌,KB人口腔上皮癌,SGC-7901人胃癌,HepG2人肝癌,HeLa人宫颈癌和HEK-293T非癌细胞系的体外抗增殖活性。此外,通过电泳迁移谱研究研究了化合物与DNA之间的相互作用。
