human cell lines (HCT116, A549, MCF7, PC3, and HEPG2). The compounds showed higher cytotoxic activity against (A549, HCT116, and MCF7) cell lines. The loss of the cytotoxic activity was observed in the case of PC3 and HEPG2 cell lines. Compound 5b showed the highest cytotoxic activity against the three lines (A549, HCT116, and MCF7). In an attempt to know the mechanism followed by the compounds to inhibit
通过酸催化四醛6a-d与八当量的3-氨基丁-2-腈2的缩合反应合成新型四(2,6-二甲基-4-苯基-1,4-二氢吡啶基)甲烷5a-d被报道。5a–d的结构由不同的光谱工具确定。在体外,对五种不同的人类细胞系(HCT116,A549,MCF7,PC3和HEPG2)进行了新型四足动物1,4-二氢吡啶(5a-d)的细胞毒性筛选测定。这些化合物对(A549,HCT116和MCF7)细胞系显示出更高的细胞毒活性。在PC3和HEPG2细胞系中观察到细胞毒性活性的丧失。化合物5b对三个系(A549,HCT116和MCF7)显示出最高的细胞毒活性。为了了解化合物抑制细胞增殖的机制,选择了化合物5b进行分子研究。化合物5b通过诱导肿瘤抑制蛋白p53,BAX以及通过使用实时PCR降低BCL2基因表达来抑制抗凋亡蛋白,从而诱导凋亡抑制人结肠腺癌HCT116细胞的增殖。关于细胞周期分析,化合物5b诱导了针对这三个
