6-[(aminoalkyl)amino]-substituted 7H-benzo[e]perimidin-7-ones as novel antineoplastic agents. Synthesis and biological evaluation.
A class of chromophore-modified anthracenediones with an additional pyrimidine ring incorporated into the chromophore system has been obtained in an attempt to provide compounds with diminished peroxidation activity and thus potentially lowered cardiotoxicity. Their synthesis was carried out by the reaction of 6-amino- or 6-hydroxy-7H-benzo[e]perimidin-7-one with a number of alkylamines. Potent activity was demonstrated in vitro against murine L1210 leukemia cells (equipotent with ametantrone) as well as against P388 leukemia in vivo (% T/C = 130-255). We observed that the benzoperimidines did not stimulate free radical formation, perhaps due to their poor substrate properties for NADH dehydrogenase.
