in vitro and in vivo studies revealed their good cytotoxic properties. In order to obtain some biologically active analogs of these compounds, we developped a synthesis based on the photocyclisation of tertiary N-methylated enaminones derived from cyclopentane-1,3-dione and 3 or 6-aminoquinoline. The angular cyclised compounds thus obtained were submitted to Beckmann rearrangement, preceded by the formation
吲哚喹啉生物碱隐血藤碱和吡啶咔唑生物碱玫瑰树碱备受关注,因为体外和体内研究表明它们具有良好的细胞毒性。为了获得这些化合物的一些生物活性类似物,我们基于衍生自环戊烷-1,3-二酮和3或6-氨基喹啉的叔N-甲基化烯胺酮的光环化反应,开发了一种合成方法。将如此获得的成角度的环化化合物进行贝克曼重排,然后形成Z肟。最后,使用在二苯醚中的10%钯/碳将δ-内酰胺环氧化,得到吡咯并吡咯并喹啉。这些化合物以及中间体内酰胺和环戊基吡咯并喹啉在K 562细胞和A 2780对阿霉素敏感和耐药的细胞上进行了体外测试。
