chalcones whereas for flavonol derivatives the best performance was registered for the 4-substituted derivatives. Flow cytometry analysis showed that compounds 3p and 4o induced cell cycle arrest and apoptosis as demonstrated by increased S, G2/M and sub-G1 phases. These data were corroborated by western blot and fluorescence microscopy analysis. In summary, halogenated chalcones and flavonols were successfully
通过生态友好的方法以高收率合成了一系列查尔酮和黄酮醇衍生物。用人结肠直肠癌细胞系HCT116进行药理评估,结果表明黄酮醇的抗癌活性高于查尔酮前体的抗癌活性。卤代衍生物的抗增殖活性随着B环的3-位或4-位正位的取代基从F到Cl和Br的增加而增加。此外,位置3的卤素增强了查耳酮的抗癌活性,而对于黄酮醇衍生物而言,4-取代衍生物的最佳性能则得到了证明。流式细胞仪分析表明化合物3p和4oS,G2 / M和sub-G1期增加证明细胞周期阻滞和凋亡。这些数据通过蛋白质印迹和荧光显微镜分析得到证实。总之,成功制备了卤代查耳酮和黄酮醇,并表现出很高的抗癌活性,如它们的细胞生长和对HCT116细胞的细胞周期抑制潜能(优于槲皮素)所显示的那样,它们被用作阳性对照。
