Many natural or synthetic chalcones have potential anti-tumor activity. Here, we synthesized two series of chalcone analogues containing a thieno[2,3-d]pyrimidin-2-yl group and evaluated for their cytotoxic activity towards cultured human lung cancer A549 and colorectal HCT-116 cells. Among them, compound 8d was the most cytotoxic against HCT-116 cells, with an IC50 value of 2.65 μM. Analyses of the
许多天然或合成的查耳酮具有潜在的抗肿瘤活性。在这里,我们合成了两个包含噻吩并[2,3-d]嘧啶-2-基的查耳酮类似物系列,并评估了它们对培养的人肺癌A549和结直肠HCT-116细胞的细胞毒活性。其中,化合物8d对HCT-116细胞的细胞毒性最大,IC50值为2.65μM。该化合物诱导的表型变化的分析发现,HCT-116细胞在亚G1期呈剂量依赖性积累,表明化合物8d可能诱导细胞凋亡。此外,我们发现8d触发线粒体膜电位去极化,促进HCT-116细胞中活性氧的形成,并增加早期和晚期凋亡细胞的百分比。最后,免疫印迹表明8d增加PARP-1和半胱氨酸蛋白酶3,7和9卵裂。这些数据表明化合物8d通过线粒体死亡途径诱导凋亡。
