The exceptional TOP1-targeting activity and antitumor activity of ARC-111, 1, prompted studies on similarly substituted benzo[i]phenanthridine-12-carboxylic ester and amide derivatives. These studies were extended to include 6-substituted 8,9-dimethoxy-2,3-methylenedioxy-dibenzo [c,h] [2,6]naphthyridin-5-ones, which represent reversed lactam analogues of 1. Several of these analogues retained the potent TOP1-targeting activity and cytotoxicity observed for ARG-111. (C) 2004 Elsevier Ltd. All rights reserved.
