Several chalcones were synthesized and their in vitro cytotoxicity against various human cell lines, including human breast adenocarcinoma cell line MCF-7, human lung adenocarcinoma cell line A549, human prostate cancer cell line PC3, human adenocarcinoma cell line HT-29 (colorectal cancer) and human normal liver cell line WRL-68 was evaluated. Most of the compounds being active cytotoxic agents, four of them with minimal IC50 values were chosen and studied in detail with MCF-7 cells. The compounds 1, 5, 23, and 25 were capable in eliciting apoptosis in MCF-7 cells as shown by multiparameter cytotoxicity assay and caspase-3/7, -8, and -9 activities (p < 0.05). The ROS level showed 1.3-fold increase (p < 0.05) at the low concentrations used and thus it was concluded that the compounds increased the ROS level eventually leading to apoptosis in MCF-7 cells through intrinsic as well as extrinsic pathways.
合成了几种查尔酮,并评价了它们对多种人类细胞系的体外细胞毒性,包括人乳腺腺癌细胞系MCF-7、人肺腺癌细胞系A549、人前列腺癌细胞系PC3、人腺癌细胞系HT-29(结直肠癌)以及人正常肝细胞系WRL-68。大多数化合物作为有效的细胞毒剂,其中四种具有最小IC50值的化合物被选中并详细研究了对MCF-7细胞的影响。化合物1、5、23和25能够引发MCF-7细胞的凋亡, multiparameter细胞毒性测定和caspase-3/7、-8、-9活性表明了这一点(p < 0.05)。在使用的低浓度下,活性氧(ROS)水平显示出1.3倍的增加(p < 0.05),因此得出结论,这些化合物提高了ROS水平,最终通过内源性和外源性途径导致MCF-7细胞凋亡。
