activity, topoisomerase II inhibition activity, and DNA reductivealkylation was studied for the 6-aziridinylpyrrolo[1,2-alpha]benzimidazolequinones (PBIs) and the 6-acetamidopyrrolo[1,2-alpha]benzimidazolequinones (APBIs). The PBIs are reductively activated by DT-diaphorase and alkylate the phosphate backbone of DNA via major groove interactions, while the APBIs are reductively inactivated by this enzyme
