A series of novel N-(5-benzyl-4-(tert-butyl) thiazol-2-yl)-2-(piperazin-1-yl)acetamides were designed, synthesized and evaluated for their antitumor activities in vitro. The structures of the synthesized compounds were characterized by 1H NMR, 13C NMR and elemental analysis. In general, compounds 5a, 5c and 6a showed potent antiproliferative activity against HeLa (human cervical cancer) and A549 (human lung cancer) cell lines. Compound 6a, with the best inhibitory activity against HeLa cells (IC50 = 1.6 ± 0.8 μM), was selected to investigate the induced changes of cell morphology in the HeLa cell line by means of acridine orange (AO)/ethidium bromide (EB) double staining and cell cycle analysis using flow cytometry. The results indicated that compound 6a could induce cell apoptosis and cause G1-phase arrest in the cell division cycle.
一系列新型的N-(5-苄基-4-(叔丁基)噻唑-2-基)-2-(哌嗪-1-基)乙酰胺被设计、合成并评估其体外抗肿瘤活性。合成化合物的结构通过1H NMR、13C NMR和元素分析进行表征。总体而言,化合物5a、5c和6a对HeLa(人宫颈癌)和A549(人肺癌)细胞系表现出强烈的抗增殖活性。化合物6a在HeLa细胞中的抑制活性最佳(IC50 = 1.6 ± 0.8 μM),被选中通过结合橙(AO)/溴化乙锭(EB)双重染色和流式细胞术进行细胞周期分析,研究其诱导的细胞形态变化。结果表明,化合物6a可以诱导细胞凋亡并导致细胞分裂周期中的G1期停滞。
