A new series of 9(10H)-acridinone-1,2,3-triazole derivatives were designed, synthesized and evaluated for their cytotoxic activity against human breast cancer cell lines. The acridone skeleton was prepared through the Ullman condensation of 2-bromobenzoic acid and anilines. Subsequently, it was functionalized with propargyl bromide. Then, a click reaction of the latter compound and in situ prepared 1-(azidomethyl)-4-methoxybenzene derivatives led to the formation of the desired triazole products. Finally, all products were investigated for their capability to cause cytotoxicity against MCF-7, T-47D, and MDA-MB-231 cell lines. Among them, 2-methoxy-10-((1-(4-methoxybenzyl)-1H-1,2,3-triazol-4-yl)methyl)acridin-9(10H)-one 8c exhibited the most potency $$(\hbox IC}_50}\,=}\,11.0\,\pm }\, 4.8\, \upmu \hbox M})$$ against MCF-7 cells, being more potent than etoposide $$(\hbox IC}_50}\,=}\, 12.4\,\pm }\, 4.7 \upmu \hbox M})$$ . Also, apoptosis induced by compound 8c was confirmed via acridine orange/ethidium bromide and Annexin V-FITC/propidium iodide (PI) double staining.
设计、合成并评价了一系列新的9(10H)-吖啶酮-1,2,3-三氮唑衍生物对人类乳腺癌细胞系的细胞毒活性。通过 Ullman 缩合反应,由2-溴苯甲酸和对胺制备吖啶酮骨架,随后用炔丙基溴进行功能化。然后,后者化合物与原位制备的1-(叠氮甲基)-4-甲氧基苯衍生物进行点击反应,得到所需的三氮唑产物。最后,所有产物被评估其对MCF-7、T-47D和MDA-MB-231细胞系的细胞毒性能力。其中,2-甲氧基-10-((1-(4-甲氧基苄基)-1H-1,2,3-三氮唑-4-基)甲基)吖啶-9(10H)-酮8c对MCF-7细胞表现出最高的活性(IC\(}_50}\)=11.0±4.8μM),比依托泊苷(IC\(}_50}\)=12.4±4.7μM)更有效。此外,通过吖啶橙/溴化乙锭和 Annexin V-FITC/碘化丙啶(PI)双重染色,确认了8c化合物诱导的细胞凋亡。
