albumin (BSA) binding is investigated. No reaction with nucleobase is observed. However, these iridium(III) complexes bind rapidly to GSH and can catalyze oxidation of NADH to NAD+. In addition, they show moderate binding affinity to BSA and the fluorescence quenching of BSA by the iridium (III) complexes is due to the static quenching. Third, the mode of cell death was also explored through flow cytometry
我们,在此,报告的合成,表征,发光性质,抗癌和抗细菌活性的家族通式新颖半夹心铱(III)配合物[(η的5 -Cp X)IR(C ^ N)氯] PF 6 – [Cp x =五甲基环戊二烯基(Cp *)或四甲基(联苯)-环戊二烯基(Cp xbiph)],带有通用的亚胺-N-杂环卡宾配体。在这种复杂的框架中,可以调节四个位置上的取代基,从而区别了此类复合物,并提供了大量的灵活性和机会来调节复合物的细胞毒性。配合物4和10的X射线晶体结构展现出预期的“钢琴凳”几何形状。用的例外1,2,和11,每个复杂的表演有效的细胞毒性,与IC 50(半最大抑制浓度)值范围为1.99至25.86μM朝向A549人肺癌细胞。首先,系统研究了在复杂骨架中具有不同取代基的四个位置对抗癌活性的影响,即结构与活性之间的关系。综合大楼8(IC 50= 1.99μM)具有最高的抗癌活性,其细胞毒性比临床铂药物顺铂对A549癌细
