Benzo[g][1]benzopyrano[4,3-b]indol-6(13H)-ones (BBPIs) are potent anticancer compounds having unique BBPIs ring system designed on the basis of the marine natural product lamellarin D. In this study, we describe an alternative synthesis of a 2-demethoxy series of BBPIs, employing van Leusen pyrrole synthesis and an intramolecular Heck reaction as the key reactions. Cytotoxicity of the derivatives against several cancer and normal cell lines is reported.
苯并[g][1]苯并吡喃[4,3-b]吲哚-6(13H)-酮(BBPIs)是具有独特 BBPIs 环系的强效抗癌化合物,该环系是基于海洋天然产物拉米林 D 设计的。在这项研究中,我们描述了一种替代的 2-去甲氧基系列 BBPIs 的合成方法,采用范吕森吡咯合成和分子内 Heck 反应作为关键反应。报道了衍生物对几种癌细胞和正常细胞系的细胞毒性。
