This work reports the synthesis and characterization of cytotoxic gold(III) complexes of a series of 5-methyl-5-(pyridyl)-2,4-imidazolidenedione ligands. Based on the elemental analysis and inductively coupled plasma-mass spectrometry (ICP-MS), the complexes have the general formula AuL1Cl2 (1), [Au(L2)2Cl2][AuCl4] (2), and [Au(L3)2Cl2][AuCl4] (3) (L1, L2, and L3 = 5-methyl-5-(2,3, and 4-pyridyl)-2
这项工作报告了一系列5-甲基-5-(吡啶基)-2,4-咪唑烷二酮配体的细胞毒性金(III)配合物的合成和表征。基于元素分析和电感耦合等离子体质谱(ICP-MS),该配合物的通式为Au L1 Cl 2(1),[Au(L2)2 Cl 2 ] [AuCl 4 ](2)和[Au(L3)2 Cl 2 ] [AuCl 4 ](3)(L1,L2和L3分别为5-甲基-5-(2,3和4-吡啶基)-2,4-咪唑啉二酮。通过IR,1 H,13 C NMR光谱分析,摩尔电导率,循环伏安法和DFT方法研究了所有化合物。研究表明,该配合物具有方形平面几何形状,是d 8配合物共有的,配体分子以N配位双齿(1)和单齿(2和3)的方式与金属中心配位。DFT对不同几何异构体的研究表明,在气相和溶液相中,2和3的反式异构体都比2和3的反式稳定。顺式的。已经研究了分别在六种细菌菌株和两种人肿瘤细胞系中评估的这些化合物的抗菌活性和
