exhibited broad-spectrum antiproliferative activities against a panel of tumor cell lines. The promising in vitro antiproliferative activity and structural novelty of 1a prompted us to investigate the synthesis of five analogs of 1a and test their antiproliferative activities. The most potent analogue, 1h, exhibited enhanced antiproliferative activities compared with the parent 1a, and exhibited an
在基于细胞的新型抗增殖剂筛选中,带有苯并呋喃磺酰胺支架的命中化合物1a对一组肿瘤细胞系表现出广谱抗增殖活性。有前景的1a体外抗增殖活性和结构新颖性促使我们研究1a的5种类似物的合成并测试其抗增殖活性。最有效的类似物1h与亲本1a相比具有增强的抗增殖活性,对NCI-H460细胞的IC 50值为4.13μM,而阳性对照为顺铂4.52μM。流式细胞仪分析显示1h在低微摩尔浓度下体外诱导NCI-H460细胞中显着水平的细胞凋亡。这些结果表明1a及其基于其苯并呋喃磺酰胺支架的类似物可能构成一类新型的抗增殖剂,值得进一步研究。
