An intramolecular radical cyclization reaction of 4-bromo-3-arylisoquinolines 11a-c allowed the efficient synthesis of 11-methylindenoisoquinolines 2a-c. 5-(2-Aminoethylainino)indeno[1,2-c]isoquinolin-11-one 4 was also prepared in the convenient manner. The synthesized compounds were tested in vitro for cytotoxicity and DNA-topoisomerase 1 (top 1) inhibitory activity. The dramatic enhancement of top 1 inhibitory activity of 4 was explained by a docking study using the FlexX program. (c) 2007 Elsevier Ltd. All rights reserved.
