Benzoperimidines, a novel group of antitumor anthracenedione analogues, are of interest due to their ability to overcome multidrug resistance of tumor cells (Stefanska, B., Dzieduszycka, M., Bontemps-Gracz, M. M., Borowski, E., Martelli, S., Supino, R., Pratesi, G., De Cesare, MA., Zunino, F., Kusnierczyk, H., Radzikowski, Cz. J. Med. Chem. 1999, 42, 3494). Although the structural factor essential for exhibiting this desirable property is the presence in the molecule of a fused heterocyclic ring, the cytotoxicity against resistant cells is highly influenced by the nature and location of the substituents. A series of novel synthetic derivatives, comprising monohydroxylated benzoperimidines and 2-aminobenzoperimidines, allowed the establishment of an in vitro structure-activity relationship for a panel of leukemia sensitive, as well as P-gp dependent multidrug resistance (MDR) and multidrug resistance associated protein dependent resistance (MRP) resistant cell lines. The membrane affinity for the compounds has also been determined. (C) 2002 Elsevier Science Ltd. All rights reserved.
