Compounds and pharmaceutically acceptable salts thereof of Formula I are disclosed. Certain compounds and salts of Formula I are active as Topl and / or Tdpl inhibitors. The disclosure provides pharmaceutical compositions containing a compound of Formula I as the only active agent, or optionally containing one or more additional active agents. Methods of using compounds of Formula I to treat cancer are provided in this disclosure. The disclosed compounds of Formula I may be used alone to treat cancer, but may also be used in combination with another active agent, such as a Topl inhibitor, for example, camptothecin or a camptothecin analogue.

DNAtopoisomerase IB (TOP1) regulates DNA topological structure in many cellular metabolic processes and is a validated target for development of antitumor agents. Our previous study revealed that the benzophenanthridone scaffold is a novel chemotype for the discovery of TOP1 inhibitors. In this work, a series of novel 5-aminoethyl substituted benzophenanthridone derivatives have been synthesized and
