N-Substituted indenoisoquinoline compounds, and pharmaceutical formulations of N-substituted indenoisoquinoline compounds are described. Also described are processes for preparing N-substituted indenoisoquinoline compounds. Also described are methods for treating cancer in mammals using the described N-substituted indenoisoquinoline compounds or pharmaceutical formulations thereof.
Tyrosyl-DNAphosphodiesteraseI (TDP1) repairs stalled topoisomerase I (Top1)-DNA covalent complexes and has been proposed to be a promising and attractive target for cancer treatment. Inhibitors of TDP1 could conceivably act synergistically with Top1inhibitors and thereby potentiate the effects of Top1 poisons. This study describes the successful design and synthesis of 2-position-modified indenoisoquinolines
