Title:
OXYNITIDINE DERIVATIVES USEFUL AS INHIBITORS OF TOPOISOMERASE IB (TOP1) AND/OR TYROSYL-DNA PHOSPHODIESTERASE 1 (TDP1)
Document Type and Number:
WIPO Patent Application WO/2020/023700
Kind Code:
A3
Abstract:
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.
