sufficient stability in aqueous solution. Most of the complexes showed good anticancer activities toward A549 cancer cells, which were higher than the clinical drug cisplatin. In this series, complex Ir8 displayed the highest anticancer activity against A549 cells (IC50 = 4.7 μM), showing an approximately 4.5-fold more potent activity than cisplatin (IC50 = 21.30 μM). The structure–activity relationship
的合成,表征,和辅酶催化NADH转化为NAD的能力+和半夹心铱(III)与[(η通式配合物的抗癌活性5 -Cp X)IR(P ^ N)CL] PF 6研究了(Cp x:Cp *或联苯Cp xbiph衍生物; P ^ N:各种膦亚胺配体)。复合物Ir4的晶体结构在铱(III)中心周围显示出钢琴凳的几何形状。这类铱(III)配合物在水溶液中具有足够的稳定性。大多数复合物对A549癌细胞显示出良好的抗癌活性,高于临床药物顺铂。在这个系列中,复杂的Ir8对A549细胞具有最高的抗癌活性(IC 50 = 4.7μM),显示出比顺铂(IC 50 = 21.30μM)强大约4.5倍的有效活性。结构-活性关系研究表明,这些配合物的细胞毒性可能主要归因于铱(III)与配位原子之间的配位,而亚胺N取代基的性质可能不是影响细胞毒性的主要因素。此外,该复合物家族通过细胞应激导致细胞死亡,诱导细胞凋亡和坏死,活性氧
