designed new 3-arylthio- and 3-aroyl-1H-indole derivatives 3-22 bearing a heterocyclic ring at position 5, 6 or 7 of the indole nucleus. The 6- and 7-heterocyclyl-1H-indoles showed potent inhibition of tubulin polymerization, binding of colchicine to tubulin and growth of MCF-7 cancer cells. Compounds 13 and 19 inhibited a panel of cancer cells and the NCI/ADR-RES multidrug resistant cell line at low
我们设计了新的3-芳硫基和3-芳基-1H-吲哚衍生物3-22,其在吲哚核的5、6或7位带有杂环。6-和7-杂环基-1H-吲哚显示出对微管蛋白聚合的有效抑制,秋水仙碱与微管蛋白的结合以及MCF-7癌细胞的生长。化合物13和19在低纳摩尔浓度下抑制了一组癌细胞和NCI / ADR-RES多药耐药细胞系。浓度为50 nM的化合物13在HeLa细胞中诱导77%的G2 / M,浓度为20 nM时引起50%的有丝分裂稳定停滞。作为HepG2细胞的抑制剂(IC50 = 20 nM),13的毒性是19的4倍。化合物13是纳摩尔浓度的人U87MG胶质母细胞瘤细胞的有效抑制剂,比以前报道的芳基硫代吲哚高出近一个数量级。
