wherein all of the complexes were found to display more pronounced activity than their ligand counterparts. Complexes 7–12 bearing triphenylphosphine displayed significant cytotoxicity, among which complex 12 showed IC50 values of 0.6 ± 0.9, 0.1 ± 0.8, and 0.1 ± 0.2 μM against MCF-7, T47-D, and MDA-MB-231 cell lines, respectively. The most active complexes were tested for their mode of cell death through
含有硝基取代呋喃酰硫脲配体的半夹心 Ru(II) 配合物,通式为 [( η 6 - p -伞花烃)RuCl 2 (L)] ( 1 – 6 ) 和 [( η 6 - p -伞花烃)RuCl (L)(PPh 3 )] + ( 7– - 12 ) 已被合成并表征。光谱数据显示配体通过“S”原子与 Ru(II) 离子进行单齿配位,与此相反,单晶 X 射线结构显示出不寻常的二齿 N、S 配位,与金属中心形成四元结构。戒指。通过吸收、发射和粘度测量进行的相互作用研究揭示了 Ru(II) 复合物与小牛胸腺 (CT) DNA 的嵌入。该复合物与牛血清白蛋白(BSA)也表现出良好的相互作用。此外,专门针对乳腺癌细胞(即 MCF-7、T47-D 和 MDA-MB-231)探索了它们的细胞毒性,其中发现所有复合物都比其配体对应物表现出更显着的活性。带有三苯基膦的配合物7 – 12表现出显着的细胞毒性,其中配合物
