The first total synthesis of the indole alkaloids (±)-aplicyanins A, B, and E, plus 17 analogues, all in racemic form, is reported. Modifications to the parent compound included changing the number of bromine substituents on the indole, the nature of the substituents on the indole nitrogen (H, Me, or OMe), and/or the oxidation level of the heterocyclic core tetrahydropyrimidine. Each compound was screened
首次报道了吲哚生物碱(±)-Aplicyanins A,B和E以及17种类似物的全部外消旋形式的全合成。对母体化合物的修饰包括改变吲哚上的溴取代基的数目,吲哚氮上的取代基的性质(H,Me或OMe)和/或杂环核心四氢嘧啶的氧化水平。针对三种人类肿瘤细胞系筛选每种化合物,新合成的化合物中有14种显示出明显的细胞毒性。测定结果用于建立构效关系。这些结果表明,在某些化合物中,吲哚5位的溴的存在对活性至关重要,而亚胺氮上的乙酰基也是如此。
