clinical trials for the treatment of metastatic tumors. The reaction of guanidine ligands with [RuCl(μ-Cl)(η6-p-cymene)]2 yielded monometallic Ru(II) complexes with N,N-type (1) and O,N-type (2 and 3) ligands, whereas both monometallic (O,N) (7) and bimetallic Ru(II) (4–6) complexes were obtained when [RuCl(μ-Cl)(η6-benzene)]2 was used as a precursor. The complexes were characterized using analytical
在KP1019和NAMI-A进入用于治疗转移性肿瘤的II期临床试验后,钌复合物作为抗癌药物而引人入胜。胍配体与反应将[RuCl(μ-Cl)的(η 6 - p -cymene)] 2,得到单金属的Ru(II)络合物与N,N型(1)和O,N型(2和3)配体,而这两个单金属(O,N)(7)和双金属钌(II)(4 - 6)获得的复合物时将[RuCl(μ-Cl)的(η 6 -苯)] 2被用作前身。使用分析,光谱学(紫外可见,FT-IR,NMR和质量)和单晶X射线晶体学技术对复合物进行表征。配合物的稳定性通过紫外可见光谱法进行了测试。使用各种光谱技术研究了复合物与小牛胸腺(CT)DNA和牛血清白蛋白的相互作用。光谱和粘度实验表明,由于p的疏水性增加,Ru– p- cymene复合物的内在DNA结合亲和力大于类似的Ru–苯复合物。-cymene戒指。使用MTT分析评估了复合物对HepG2,A549和Ve
