  Synthesis of 13-amino costunolide derivatives as anticancer agents

  摘要：

  A number of costunolide derivatives (4a-p) have been synthesized and evaluated for their in vitro cytotoxicity against eight tumor and a non-tumor cell lines. Compound 4d showed around 2-fold better cytotoxicity against SW-620 (colon) cell line with improved safety index than costunolide (1). While compounds 4e, 4g, and 4p have shown around 2- to 3-fold better cytotoxicity against MIAPaCa2 (pancreas), K-562 (leukemia) and PA-1 (ovary) cell lines as well as better safety index in comparison to costunolide (1). Compound 4p also exhibited cytotoxicity against HBL100 (breast) cell line with 2-fold better safety index. Structure-activity relationship has been described. (c) 2006 Elsevier Ltd.

  An efficient and mild method has been developed for the amination of β-methoxy amides (γ-lactones) including natural products michelolide, costunolide and parthenolide derivatives by using lithium chloride in good yields. This reaction is applicable to a wide range of substrates with good functional group tolerance. Mechanism studies show that the reactions undergo a LiCl promoted MeOH elimination

  已经开发了一种高效温和的方法，用于以良好收率使用氯化锂胺化 β-甲氧基酰胺（γ-内酯），包括天然产物 michelolide、costunolide 和 parthenolide 衍生物。该反应适用于广泛的具有良好官能团耐受性的底物。机理研究表明，反应经历了 LiCl 促进的 MeOH 从底物中消除形成相应的 α,β-不饱和中间体，然后是胺的迈克尔加成。
