exchange properties of these complexes and their biomolecule binding, noting in particular the stability of the M–CNHC bond. In addition, we demonstrated the ability of the complexes to inhibit the selenoenzyme thioredoxin reductase (TrxR), suggested as an important target for anticancer metal–NHC complexes, and their cytotoxicity in human tumor cells. It was found that the most potent TrxR inhibitor diiodido(1
金属(芳烃)结构作为抗癌药效基团的前景促使人们对该化学领域进行了深入的探索。尽管N-杂环卡宾(NHC)配体广泛用于催化,但直到最近才将它们用于药用金属配合物中。出人意料的是,已经报道了较少的研究,其中NHC配体与Ru II(芳烃)药效团协同作用,而与Os II协同作用则更少。(芳烃)药效团。在这里,我们提出了一项系统研究,其中我们将对称取代的甲基和苄基衍生物与非对称甲基/苄基类似物进行了比较。通过金属中心和卤代配体的变化,对这些配合物的配体交换特性及其生物分子结合进行了深入研究,特别是M–C NHC键的稳定性。此外,我们证明了该复合物抑制硒酶硫氧还蛋白还原酶(TrxR)的能力,这被认为是抗癌金属-NHC复合物的重要靶标及其在人肿瘤细胞中的细胞毒性。据发现,最有效的TrxR抑制剂diiodido(1,3- dibenzylbenzimidazol -2-亚基)(η 6 -对异丙基苯甲烷)钌(
