A series of novel imidazo[4,5-d]azepine compounds derived from marine natural product ceratamine A were designed and synthesized in 7 steps. Most compounds exhibited comparable cytotoxicity against five human cancer cell lines (HCT-116, HepG2, BGC-823, A549 and A2780) to natural product ceratamine A. Compound 1k, bearing methoxy group at C-14, C-15 and C-16, showed the best in vitro cytotoxicity, which
设计并合成了一系列来自海洋天然产物ceratamine A的新型咪唑并[4,5- d ]氮杂氮杂化合物,并分7个步骤合成。大多数化合物对五种人类癌细胞系(HCT-116,HepG2,BGC-823,A549和A2780)表现出与天然产物ceratamine A相当的细胞毒性。化合物1k,在C-14,C-15和C-16处带有甲氧基,显示出最佳的体外细胞毒性,优于ceratamineA。结构和活性关系研究表明,N -3上的苄氧甲基对细胞毒性起重要作用。
