In the search of new compounds with antineoplastic activity, we have analysed the effect of several structural modifications on the nucleus 6-benzo[b]thiophenesulphonamide 1,1-dioxide on its cytotoxic activity on tumour cells. Lipophilic substituents on the sulphonamide group significantly increased the cytotoxic activity measured using a panel of human tumour cell lines. Only slight variations on
在寻找具有抗肿瘤活性的新化合物时,我们分析了几种结构修饰对6-苯并[b]噻吩磺酰胺1,1-二氧化物核对肿瘤细胞的细胞毒活性的影响。使用一组人类肿瘤细胞系测得的磺酰胺基团上的亲脂取代基显着提高了细胞毒性活性。当磺酰胺基占据系统的位置5时,仅在细胞毒性上获得了很小的变化。最具活性的化合物是N-4-甲氧基苯基衍生物15,它对HT-29,CCRF-CEM,K-562和MEL-AC细胞的GI(50)值为1-9 nM,而对HTB-200的GI(50)值为200 nM。 54格。为了获得细胞毒性衍生物,似乎需要自由进入杂环系统的3位。
