Synthesis and cytotoxic activity of different open indolocarbazole alkaloid analogues
摘要:
An array of 4-(aryl or indolyl)pyrrolo[3,4-c]carbazole-1,3-diones (open analogues of indolocarbazole alkaloids), 10-(aryl or indolyl)pyrrolo [3,4-b]carbazole-1,3-diones, and different derivatives have been prepared using a Diels-Alder plus Fischer indolization approach and tested as cytotoxic agents. Some representative compounds display interesting cytotoxic profiles. (C) 2003 Elsevier Ltd. All rights reserved.

The preparation of a range of open analogues of arcyriaflavin A is described. The synthetic approach is based on the use of perhydroisoindole-1,3,5-triones as key intermediates, which were obtained via Diels-Alder methodology using 1-aryl-3-siloxy-1,3-butadienes as starting materials. Fischer indolization and aromatization processes afforded different methoxy-substituted arylpyrrolocarbazoles. The stereochemistry and conformation of the Diels-Alder products and the regiochemistry of the indolization reactions are supported by NMR and molecular modeling studies.
