Novel Furoquinolinediones as Inhibitors of TDP2 and Their Potential Use to Treat Cancer

Primary tabs

Novel Furoquinolinediones derivatives may act as an anti-cancer agent by the inhibition of tyrosyl-DNA phosphodiesterase 2 (TDP2), an enzyme involved in DNA repair and transcription factor activation. These Furoquinolinediones derivatives may also be used in combination therapies to effectively kill cancer cells.

Description of Technology

The invention relates to novel Furoquinolinediones derivatives and their ability to inhibit the enzyme tyrosyl-DNA phosphodiesterase 2 (TDP2), and therefore to serve as anti-cancer agents. Furthermore, these compounds can be used in combination with topoisomerase II (Top2) inhibitors, such as etoposide or doxorubicin, to more effectively kill cancer cells in a synergistic fashion.  Pharmaceutical compositions containing these novel Furoquinolinediones and methods of treatment comprising administering of such compositions are disclosed in the invention.  Researchers at the NCI seek licensing and/or co-development research collaborations.

Potential Commercial Applications

• Furoquinolinediones derivatives can potentially be utilized for cancer treatment either as stand alone or in combination with other drugs such as Top2 inhibitors

Competitive Advantages

• Combination therapies based on the association of a TDP2 and a Top2 inhibitor because of their synergistic effect should allow the decrease of the effective dosage. Their therapeutic benefit should be observed at non-toxic concentrations for normal cells as it has already been demonstrated for PARP inhibitors in BRCA-deficient tumors.
