around the Cu centers was confirmed to be tetrahedral or octahedral. The cytotoxic activity of the new compounds was evaluated using MCF-7 (human breast adenocarcinoma), A2780 (human ovary adenocarcinoma) and HT29 (human colon adenocarcinoma), in addition to MRC5 (normal human fetal lung fibroblast) cells using the MTT cytotoxicity assay. The Schiff base 12c and the Cu complex 13b were the most active
使用光谱和分析技术设计,合成和分析了两个新颖的系列,包括吡咯嗪5-甲酰胺的席夫碱及其Cu(II)配合物。分析结果表明以1:1或1:2(金属:配体)的比例形成了配合物。Cu中心周围的几何形状被确认为四面体或八面体。除了MRC5(正常人胎儿肺成纤维细胞)细胞外,还使用MCF-7(人乳腺腺癌),A2780(人卵巢腺癌)和HT29(人结肠腺癌)对新化合物的细胞毒活性进行了MTT细胞毒性试验。 。Schiff碱12c和Cu络合物13b在具有IC 50的两个系列中最活跃相对于三种细胞系,其值在0.14–2.54μM的范围内。另外,Cu配合物13e对HT29表现出优异的活性,IC 50 =0.05μM。7-氰基-N-(4-甲氧基苯基)-6-((3-苯基亚芳基)氨基)-2,3-二氢-1 H-吡咯烷嗪-5-羧酰胺(12c)对苯丙胺具有很高的选择性(6-13倍)癌细胞超过正常细胞;并且它在细胞周期分析期间诱
