Synthesis and topoisomerase I inhibitory activity of a novel diazaindeno[2,1-b]phenanthrene analogue of Lamellarin D
摘要:
A novel 5-oxa-6a,8-diazaindeno[2,1-b]phenanthren-7-one scaffold was designed and synthesized as an active analogue of the cytotoxic marine alkaloid Lamellarin D. The design was based on molecular modeling of the site of interaction of Lamellarin D with DNA-topoisomerase I cleavable complex, whereas the synthesis capitalized on a simple Friedel-Crafts cyclization of indole to a beta-carbolinone nucleus. The product exhibited topoisomerase I poisoning activity and submicromolar cytotoxicity on human non-small cell lung cancer H460 cell line. (C) 2011 Elsevier Ltd. All rights reserved.

Different synthetic approaches to functionally substituted benzylamines were examined: reductive amination of alkyl aryl ketones and reduction of aromatic aldehyde oximes. The most efficient procedures were used to prepare a series of previously unknown hydroxy-, alkoxy-, and halogen-substituted benzylamines.
