of the synthetic compounds were screened against a panel of human cancer cell lines, human breast carcinoma MCF-7 cells, human liver carcinoma HepG2 cells and L02 normal cell line by MTT assay. By analyzing the structure–activity relationship among the synthetic compounds, it was found that 2-(phenylamino) selenazolo [5,4-b] pyridine, (PSeD, 7) had higher growth inhibitory effect on MCF-7 cells.

合成了一系列硒代吡啶并吡啶衍生物,并通过X射线衍射,高分辨率NMR和质谱进行了表征。在体外合成的化合物的抗癌活性进行了筛选对人癌症细胞系,人乳腺癌MCF-7细胞,人肝癌HepG2细胞,并通过MTT测定L02正常细胞系的面板。通过分析合成化合物之间的结构-活性关系,发现2-(苯基氨基)硒唑并[5,4-b]吡啶(PSeD,7)对MCF-7细胞具有更高的生长抑制作用。通过流式细胞术和ROS测定评估细胞死亡的细胞内机制,这表明PSeD通过清除细胞内ROS可以诱导MCF-7细胞凋亡。两者合计,我们认为PSeD是一种抗氧化剂,可以通过诱导细胞凋亡来抑制癌细胞的生长。
