((E)‐3‐((6‐p‐tolyl‐2‐(3,4,5‐trimethoxyphenyl)imidazo[2,1‐b][1,3,4]thiadiazol‐5‐yl)methylene)indolin‐2‐one), and 15 ((E)‐6‐chloro‐3‐((6‐phenyl‐2‐(3,4,5‐trimethoxyphenyl)imidazo[2,1‐b][1,3,4]thiadiazol‐5‐yl)methylene)indolin‐2‐one) exhibited potent anti‐proliferative activity. Treatment with these three compounds resulted in accumulation of cells in G2/M phase, inhibition of tubulin assembly, and increased
合成了由A,B,C和D环系统组成的一系列咪唑并[2,1 b ] [1,3,4]噻二唑连接的羟吲哚,并研究了其在多种人类癌细胞系中的抗增殖活性;测试化合物在C环和D环上被不同取代。其中,化合物7((E)-5-氟-3-3 -((6-对甲苯基-2-(3,4,5-三甲氧基苯基)-咪唑[2] ,1- b ] [1,3,4]噻二唑-5-基)亚甲基)吲哚-2--1),11((E)-3-((6 - p-甲苯基-2-(3,4, 5-三甲氧基苯基)咪唑并[ 2,1- b ] [1,3,4]噻二唑-5-基)亚甲基)吲哚-2--1)和15((E)-6-氯-3-((6-苯基-2-(3,4,5-三甲氧基苯基)咪唑[ 2,1- b ] [1,3,4]噻二唑-5-基)亚甲基)吲哚啉- 2‐1)表现出有效的抗增殖活性。用这三种化合物处理可导致细胞处于G 2 / M期积累,抑制微管蛋白装配,并增加细胞周期蛋白B1蛋白水平。化合物7显示的有效的细胞毒性,与IC
