Abstract Synthesis of ethylene linked tris benzimidazolium bromide salts that serve as precursors for the tri-NHC ligands in the respective tri-NHC trinuclear silver(I) complexes is described (NHC = N-heterocyclic carbene). Different wingtip substituents were selected (benzyl, n-butyl, cyclopentyl, 2-methylene benzonitrile, n-decyl) to furnish five new tris benzimidazolium salts (1-5) and the respective
摘要描述了乙烯连接的三苯并咪唑鎓溴化物盐的合成,该盐用作相应三 NHC 三核银 (I) 配合物中三 NHC 配体的前体(NHC = N-杂环卡宾)。选择不同的翼尖取代基(苄基、正丁基、环戊基、2-亚甲基苄腈、正癸基)以提供五种新的三苯并咪唑鎓盐(1-5)和各自的三 NHC 三核银(I)配合物(6- 10)。通过确定它们的 IC50 值并评估它们对选定细胞系的抗增殖活性,评估了合成和表征的化合物 (1-10) 对人结肠、人乳腺癌和人上皮样子宫颈癌细胞系的细胞毒性潜力。
