Abstract New benzimidazolium salts were synthesized as N-heterocyclic carbene precursors. These NHC precursors were metallated with Cu2O and CuI in acetone and water under reflux to give novel copper(I) complexes. The structures of these benzimidazolium salts and copper(I) complexes were characterized on the basis of elemental analysis, 1H NMR, 13C NMR, IR and LC–MS spectroscopic techniques. The (NHC)Cu(I)
摘要 合成了新的苯并咪唑鎓盐作为 N-杂环卡宾前体。这些 NHC 前体在丙酮和水中在回流下用 Cu2O 和 CuI 金属化,得到新的铜 (I) 配合物。这些苯并咪唑盐和铜 (I) 配合物的结构基于元素分析、1H NMR、13C NMR、IR 和 LC-MS 光谱技术进行表征。(NHC)Cu(I) 复合物 3-4 已针对 MCF7 和 MDA-MB-231 癌细胞、大肠杆菌、耐甲氧西林金黄色葡萄球菌 (MRSA) 和白色念珠菌微生物、利什曼原虫主要前鞭毛体和无鞭毛体、弓形虫寄生虫进行了测试并在体外对抗 Vero 细胞系。合成的铜NHC卡宾配合物4b(1,3-bis(2,3,4,5,6-pentamdthylbenzyl)-2, 3-二氢-1H-苯并[d]咪唑-2-基)氯化铜(I))对 MCF7 癌细胞最具活性(半数生长抑制浓度 (IC50) = 0.3 µg mL-1),以及对大肠杆菌(抑制区
