we have synthesized a new copper(II) complex [Cu(qmbn)(q)(Cl)] (1) (where, qmbn = 2-(quinolin-8-yloxy)(methyl)benzonitrile and q = 8-hydroxyquinoline) and structurally characterized by single crystal X-ray, Powder-XRD, FTIR and thermogravimetric analysis (TGA). The structural analysis reveals that copper(II) ions exist in a distorted square pyramidal (τ = ∼0.1), with ligation of a chloride ion, oxygen
为了评估基于金属的化疗候选药物对结直肠癌的细胞毒性潜力,我们合成了一种新的铜 (II) 络合物 [Cu(qmbn)(q)(Cl)] ( 1 )(其中,qmbn = 2-(quinolin -8-yloxy)(methyl)benzonitrile and q = 8-hydroxyquinoline) 并通过单晶 X 射线、粉末 XRD、FTIR 和热重分析 (TGA) 进行结构表征。结构分析表明,铜(II)离子以扭曲的四方锥体(τ = ∼0.1)存在,赤道位置连接了一个氯离子、氧原子和两个氮原子,顶端位置连接了一个氧原子。复合物1对人结直肠细胞系 (HCT116)的细胞毒性潜力表明,1通过激活 Bax(促凋亡蛋白)caspases-3 和 9 蛋白,诱导线粒体介导的细胞凋亡。有趣的是,发现配合物1是一个很好的电子转移催化剂候选者,它模拟具有高转换频率(k cat = 1.03 × 10 2
