A series of new antitumour lactones containing the [3.3.0] bicyclic furano-lactone core and the halogen or azido group at the C-7 position have been designed, synthesized, and evaluated for their in vitro antitumour activity against a panel of human tumour cell lines. Some of the analogues displayed powerful antiproliferative effects to certain human tumour cells, but all of them were devoid of any
设计,合成并评估了一系列新的抗肿瘤内酯,这些内酯包含[3.3.0]双环呋喃内酯核心和C-7位置的卤素或叠氮基,并在体外对一组人类肿瘤具有抗肿瘤活性。细胞系。一些类似物对某些人类肿瘤细胞显示出强大的抗增殖作用,但它们都没有对正常胎儿肺成纤维细胞(MRC-5)产生任何细胞毒性。SAR研究表明,这些内酯的结构特征可能会影响其抗增殖活性。它们是:存在于C-7位置的取代基的性质,在C-7位置的立体化学,在C-7位置不存在苯基。流式细胞仪数据表明合成的类似物在K562细胞培养物中的细胞毒性作用是由细胞凋亡介导的,另外揭示了这些分子诱导了这些细胞的细胞周期分布变化。蛋白质印迹分析的结果表明,大多数合成的化合物以半胱天冬酶依赖性方式诱导K562细胞凋亡。
