The biological efficacy of arene ruthenium complexes is currently of great interest due to the significance of arene moieties, chelates, and metal centers in defining and controlling their anticancer activity. The synthesis of six new arene ruthenium(II) complexes containing biphenyl benzhydrazone ligands of general composition [(η6-benzene)Ru(L)Cl] (1–3) and [(η6-p-cymene)Ru(L)Cl] (4–6, L = biphenyl
由于芳烃部分、螯合物和金属中心在定义和控制其抗癌活性方面的重要性,芳烃钌配合物的生物学功效目前引起了人们的极大兴趣。六种新的芳烃钌(II)配合物的合成,含有一般组成的联苯苯腙配体[(η 6 -苯)Ru(L)Cl] ( 1 – 3 ) 和 [(η 6 -对伞花烃)Ru(L)氯] ( 4 - 6, L = 联苯苯腙),本研究描述了它们的抗增殖特性。通过元素分析和光谱方法,如傅里叶变换红外 (FT-IR)、紫外-可见、核磁共振和高分辨率质谱 (HR-MS) 技术,已成功合成并彻底表征了这些配合物。通过单晶 X 射线衍射 (XRD) 技术证实了腙配体的偶氮甲碱氮和亚胺氧与钌金属的配位以及钌离子周围存在拟八面体几何结构。此外,所有复合物对癌性 A549(肺癌)、MDA-MB-231(乳腺癌)和 HEPG2(肝癌)和非癌性 HEK-293(人肾)细胞的体外细胞毒性进行了评估,发现以低 IC 为佳50与
