  Synthesis and biological evaluation of 2′,5′-dimethoxychalcone derivatives as microtubule-targeted anticancer agents

  摘要：

  A series of novel 2',5'-dimethoxylchalcone derivatives including 18 new compounds were synthesized and evaluated for cytotoxicities against two human cancer cell lines, NTUB1 ( human bladder cancer cell line) and PC3 ( human prostate cancer cell line). All these derivatives except for 21 exhibited significant cytotoxic effect against NTUB1 and PC3 cell lines. Compounds 13 and 17 with 4-carbamoyl moiety showed potent inhibitory effect on growth of NTUB1 and PC3 cells. Flow cytometric analysis demonstrated that treatment of NTUB1 cells with 1 mu M 13 and 17 induced G1 phase arrest accompanied by an increase in apoptotic cell death of NTUB1 cells after 24 h. Treatment of PC3 cells with 1 mu M and 3 mu M 13, and 1 mu M and 3 mu M 17 induced S and G1, and G1 and G2/M phase arrests, respectively, accompanied by an increase in apoptotic cell death. These data suggested that 13 and 17 with different 4-carbamoyl moiety displayed same cell cycle arrest in NTUB1 cells while different doses of 13 and 17 revealed different cell cycle arrest in PC3 cells. Cell morphological study of 17 indicated that more cells rounding up or dead associated with tubulin polymerization. Compound 17 showed an increased alpha-tubulin level in polymerized microtubule fraction in a dose-dependent manner while 500 nM paclitaxel also showed similar effect in NTUB1 cells by Western blot analysis. The result suggested that 17 may be used as microtubule-targeted agents. (C) 2010 Elsevier Ltd. All rights reserved.

  摘要：

  揭示了一系列治疗癌症的2′,5′-二甲氧基茴香酮衍生物，其中2,5-二甲氧基苯乙酮和甲基4-甲醛苯甲酸酯缩合形成4-羧基-2′,5′-二甲氧基茴香酮（化合物1），进一步与烷基卤化物或胺反应以合成化合物2-17的茴香酮衍生物。此外，2,5-二甲氧基苯乙酮与5-甲醛-2-噻吩羧酸反应形成化合物18（3-（3-噻吩）羧基-1-（2,5-二甲氧基苯基）丙-2-烯-1-酮）。合成的2′,5′-二甲氧基茴香酮衍生物可作为微管靶向的微管蛋白聚合剂。
