number of human tumour cell lines were recorded and compared with those observed for lead molecule 1. Some of the synthesized compounds showed potent in vitro antitumour activity, such as 2′-azido derivative 2, which is the most potent of all molecules under evaluation (IC50 0.004 μM against MCF-7 cells). Flow cytometry data suggest that cytotoxic effects of these compounds in the culture of K562 cells
3个噻唑呋林(合成1具有在C-2'位的氮官能团)等排物(N 3,NH 2和NH 3 +氯- )已经实现,在多步序列,从单丙酮开始ð葡萄糖。还已经从相同的糖前体合成了许多潜在的在C-2'位置具有酰基酰胺基功能的1的生物等排体。记录目标分子对多种人类肿瘤细胞系的体外细胞毒性,并与观察到的铅分子1的细胞毒性进行比较。一些合成的化合物显示出有效的体外抗肿瘤活性,例如2'-叠氮基衍生物2,这是所有被评估分子中最有效的分子(针对MCF-7细胞的IC 50 0.004μM)。流式细胞仪数据表明,这些化合物在K562细胞培养物中的细胞毒性作用可能是由细胞凋亡介导的,另外还揭示了这些分子诱导了这些细胞的细胞周期分布变化。Western印迹分析的结果表明,合成的噻唑呋喃类似物以半胱天冬酶依赖性方式诱导细胞凋亡。
