A library of imidazopyridine–propenone conjugates (8a–8u) were synthesized and evaluated for their antitumor activity against four human cancer cell lines, namely, prostate (DU-145), lung (A549), cervical (Hela) and breast (MCF-7) cancer cell lines. These conjugates showed good to moderate activity against the tested cell lines. Among them, two conjugates (8m and 8q) showed significant antiproliferative
合成了咪唑并吡啶-丙酮共轭物库(8a-8u),并评估了它们对四种人类癌细胞系(前列腺(DU-145),肺(A549),宫颈(Hela)和乳腺癌(MCF- 7)癌细胞系。这些结合物对被测细胞系表现出良好至中等的活性。其中,两种缀合物(8m和8q)显示出对人肺癌细胞系(A549)的显着抗增殖活性,IC 50值分别为0.86μM和0.93μM。流式细胞仪分析表明,这些化合物在G 2处阻止了细胞周期人肺癌细胞系(A549)中的/ M期,抑制微管蛋白聚合导致凋亡。此外,Hoechst染色,线粒体膜电位降低和膜联蛋白V-FITC分析表明细胞死亡是由于凋亡诱导所致。总体而言,本研究表明,合成的咪唑并吡啶-丙酮共轭物是有前景的微管蛋白抑制剂和凋亡诱导剂。
