Multinuclear platinumanticancer complexes are a proven option to overcome resistance of established anticancer compounds. Transferring this concept to ruthenium complexes led to the synthesis of dinuclear Ru(II)−arene compounds containing a bis(pyridinone)alkane ligand linker. A pronounced influence of the spacer length on the in vitro anticancer activity was found, which is correlated to the lipophilicity
多核铂抗癌复合物是克服已建立的抗癌化合物耐药性的一种行之有效的选择。将此概念转移到钌配合物导致合成含有双(吡啶酮)烷烃配体接头的双核 Ru(II)-芳烃化合物。发现间隔长度对体外抗癌活性的显着影响,这与复合物的亲脂性相关。集成电路50在人类肿瘤细胞系中发现了与已建立的铂类药物相同维度的值。对于三种耐药细胞系中活性最高的复合物,未观察到对顺铂前药奥索铂的交叉耐药性;事实上,在两个耐奥索铂品系中发现了 10 倍的敏感性逆转。代表性实例的(生物)分析表征表明,钌络合物快速水解,主要形成对转铁蛋白和 DNA 表现出亲和力的 diaqua 物种,表明蛋白质和核碱基都是潜在的目标。
