and the respective Ag(I) complexes were studied for their in vitro anticancer potential against human colon cancer cell line (HCT‐116) using 5‐fluorouracil as a standard. From the IC50 values of all the tested compounds, it can be postulated that there is an influential relationship between the increase in chain length of the wingtip n‐alkyl groups and the anticancer potential. The proligands 4–8 and
通过逐步的N烷基化制备了一系列对称的n烷基取代的单n烷基取代的单苯并咪唑鎓盐,并逐步增加了n烷基的链长(1 – 8)。单N-杂环卡宾(NHC)-Ag(I)配合物(9 - 16)从各自的盐衍生的是通过易于接近原位使用的Ag脱质子2 O.所有盐和复合物使用傅里叶变换红外进行了表征,1 H NMR,13 C NMR和元素分析。此外,盐3和7的结构使用X射线晶体学阐明了化合物16和配合物16,该化合物确定该单NHC-Ag(I)配合物具有线性双碳烯排列(C 2 -Ag)。以5-氟尿嘧啶为标准,研究了配体和相应的Ag(I)复合物在体外对人结肠癌细胞系(HCT-116)的抗癌能力。从所有测试化合物的IC 50值可以推测,翼尖正烷基的链长增加与抗癌潜力之间存在影响关系。所述前配体4 - 8和它们各自的复合物12 - 16与长Ñ烷基链长度(Ñ = 6-10)显示出更好的IC 50比用针对大于各自前配体和标
