Synthesis of new 3-arylisoquinolinamines: Effect on topoisomerase I inhibition and cytotoxicity

To investigate the structure-activity relationships of 3-arylisoquinolines, diverse substituted 3-aryisoquinolinamines were synthesized and tested in vitro antitumor activity against four tumor cell lines. Some of the compounds showed potent topoisomerase I inhibitory activity. Docking study of 7d with topoisomerase I-DNA complex was also performed. (C) 2003 Elsevier Ltd. All rights reserved.
