Nine chalcone derivatives containing an N-heterocyclic compound attached by its nitrogen atom to one of the benzene rings were prepared and evaluated for their antiproliferative activity against liver, gastric and neuroendocrine cancer cell lines. Most of the synthesised compounds exhibited moderate to good activity against all three cancer cell lines, but in particular, a chalcone containing a 4-(imidazol-1-yl)phenyl group and a 3,4,5-trimethoxyphenyl group showed the highest antiproliferative activity with an IC50 value of 5.39 μM against liver cancer cells.
研究人员制备了九种查尔酮衍生物,这些衍生物含有一个通过氮原子连接到其中一个苯环上的 N-杂环化合物,并评估了它们对肝癌、胃癌和神经内分泌癌细胞系的抗增殖活性。合成的大多数化合物对所有三种癌症细胞系都表现出中等至良好的活性,尤其是含有 4-(咪唑-1-基)苯基和 3,4,5- 三甲氧基苯基的查尔酮对肝癌细胞的抗增殖活性最高,IC50 值为 5.39 μM。
