A new series of 2-arylaminobenzothiazole-arylpropenone conjugates -(-) was designed, synthesized and investigated for their cytotoxic potency against the various human cancer cell lines. Most of these conjugates exhibited cytotoxic activity and inhibited tubulin polymerization effectively. Conjugates and cause cell cycle blocks in the G2/M phase in HeLa cells and treatments with and manifested increased mRNA and protein levels of the G2/M marker, cyclin B1. Immunocytochemistry revealed loss of intact microtubule structure in cells treated with and . Western blot analysis revealed that these conjugates accumulate more tubulin in the soluble fraction. Moreover, the triggering of apoptotic cell death after mitotic arrest was investigated by studying their effect on Hoechst staining, mitochondrial membrane potential, ROS generation.
设计、合成了一系列新的2-芳基氨基苯并噻唑-芳基丙烯酮共轭物-(-),并研究了它们对各种人类癌细胞系的细胞毒性。这些共轭物大多表现出细胞毒性活性,并能有效抑制微管蛋白聚合。共轭物和导致HeLa细胞在G2/M期出现细胞周期阻滞,用和处理后,G2/M标记物细胞周期蛋白B1的mRNA和蛋白质水平升高。免疫细胞化学显示,用和处理的细胞中完整的微管结构丧失。蛋白质印迹分析显示,这些共轭物在可溶性部分积累了更多的微管蛋白。此外,通过研究它们对Hoechst染色、线粒体膜电位、活性氧生成的影响,研究了有丝分裂停滞后凋亡性细胞死亡的触发情况。
