Abstract Ruthenium complexes are currently significant attention in medicinal chemistry as they offer various properties which make them an appropriate choice for drug development. Herein, a series of ruthenium(II)-p-cymene-2-aryl-imidazo-1,10-phenanthroline derivatives have been prepared and characterised by elemental analysis, infrared, LC-mass and NMR techniques. The structural and chemical properties
摘要钌配合物目前在药物化学中备受关注,因为它们具有多种特性,使其成为药物开发的合适选择。本文中,已经制备了一系列钌(II)-对-异丙基-2-芳基-咪唑基-1,10-菲咯啉衍生物,并通过元素分析,红外,LC-质谱和NMR技术对其进行了表征。结构和化学性质表明,Ru(II)配合物具有刚性,平面性,芳香性,给氢和接受氢的能力,有助于溶解性和与生物分子的相互作用。这些复合物与DNA和BSA的结合强度为104–106 M-1。在络合物存在下,溴化乙锭(EtBr)从DNA的竞争性置换揭示出插层或凹槽结合,这进一步受到粘度和计算机模拟研究的支持。这些Ru(II)复合物的细胞毒性研究是用两种癌细胞系(MDA-MB-231和HeLa)和一种人类胚胎肾细胞(HEK-293)进行的。研究表明,[(η6-p-cymene)RuCl(κ2-N,N-2-(4-氟苯基)-1H-咪唑并[4,5-f] [1,10]菲咯啉]
