Abstract

A series of bisbenzimidazoles related to Hoechst 33342 were synthesized. Data on the relative activity of these bisbenzimidazoles as topoisomerase I poisons suggest that considerable flexibility exists in the location of the tertiary alkylamine moeity. With the exception of arylamine analogs, cytotoxicity was generally consistent with their relative potency as topoisomerase I poisons.
