The present invention provides new strategies for the synthesis of compounds of the rocaglamide family and related natural products. In particular, the new biomimetic synthetic approach involves photochemical generation of an oxidopyrylium species from a 3-hydroxychromone derivative followed by 1,3-dipolar cycloaddition of the oxidopyrylium species to a dipolarophile. This approach can be used for the formation of adducts containing an aglain core structure. Methods for the conversion of aglain core structures to aglain, rocaglamide and forbaglin ring systems are also provided. The present invention also relates to the use of rocaglamide/aglain/forbaglin derivatives for the manufacture of medicaments for use in the treatment of cancer or cancerous conditions, disorders associated with cellular hyperproliferation, or NF-κB-dependent conditions.
本发明提供了合成洛卡马米类化合物及相关天然产物的新策略。特别是,新的仿生合成方法涉及从3-羟基色酮衍生物光化学生成氧化吡喃鎓物种,随后该氧化吡喃鎓物种与双极亲和物进行1,3-偶极环加成。该方法可用于形成含有阿格莱因核心结构的加合物。还提供了将阿格莱因核心结构转化为阿格莱因、洛卡马米和福巴格林环系统的方法。本发明还涉及使用洛卡马米/阿格莱因/福巴格林衍生物制造用于治疗癌症或癌变状况、与细胞过度增殖相关的疾病或NF-κB依赖性状况的药物。
