nes (or NOHCs) possess structures related to N-heterocyclic carbenes (NHCs), with potentially useful applications including the stabilization of metals. In order to prepare NOHC metal complexes, a multi-step synthesis involving mechanochemistry, and making use of ball-milling, was designed. A library of unprecedented NHOC metal complexes were tested for their cytotoxic activities against HCT116 colorectal
1,3-二(苄氧基)咪唑-2-亚基(或NOHC)具有与N-杂环卡宾(NHC)相关的结构,具有潜在的有用应用,包括金属的稳定化。为了制备 NOHC 金属配合物,设计了涉及机械化学和利用球磨的多步合成。测试了史无前例的 NHOC 金属配合物库对 HCT116 结肠直肠癌细胞系的细胞毒活性。测试表明,所研究的复合物表现出类似的活性,与配体表现出的活性相当。然而,在银配合物5的情况下发现了显着的活性,其 IC 50值为 0.75 μM,与多柔比星相当。
