Dihydroindenoisoquinolines are analogs of cytotoxic indenoisoquinoline topoisomerase I (Top1) inhibitors, exhibiting potent cytotoxicity but weak inhibitory activity toward Top1. Through COMPARE analysis, cytotoxicity studies in Top1-deficient cells, chemical synthesis and biological evaluation of methylated dihydroindenoisoquinoline 5, we demonstrated that dihydroindenoisoquinolines function as prodrugs of indenoisoquinolines in cancer cells.
