MDA-MB-231. Most compounds exhibited good cytotoxic activity against selected cell lines, being more potent than standard drug etoposide. Representatively, 8-methoxy-3-nitro-2-(4-chlorophenyl)-2H-chromene (4l) with IC50 = 0.2 μM against MCF-7 cells, was 36-times more potent than etoposide. Apoptosis as a mechanism of cell death for selected compounds 4h and 4l was confirmed morphologically by acridine
设计了一系列的2-芳基-3-硝基-2 H-色酮4a – u作为黄烷酮,β-硝基苯乙烯和硝基乙烯基二苯乙烯支架的杂合类似物。它们是由适当的β-硝基苯乙烯与水杨醛以高收率反应合成的。测试了化合物4a – u对乳腺癌细胞系MCF-7,T-47D和MDA-MB-231的体外细胞毒活性。大多数化合物对选定的细胞系均表现出良好的细胞毒活性,比标准药物依托泊苷更有效。代表性的是,具有IC 50的8-甲氧基-3-硝基-2-(4-氯苯基)-2 H-亚甲基(4l) 对MCF-7细胞= 0.2μM,效力比依托泊苷高36倍。通过a啶橙/溴化乙锭双染色和TUNEL分析,以及caspase-3活化测定,在形态学上证实了凋亡对于选定的化合物4h和4l而言是细胞死亡的机制。
