Summary for Patent: 10,058,523
Title:Benzoquinone derivative E3330 in combination with chemotherapeutic agents for the treatment of cancer and angiogenesis
Abstract: Disclosed are novel methods for the therapeutic treatment of cancer and angiogenesis. The enzyme Ape1/Ref-1, via its redox function, enhances the DNA binding activity of transcription factors that are associated with the progression of cancer. The present invention describes the use of agents to selectively inhibit the redox function of Ape1/Ref-1 and thereby reduce tumor cell growth, survival, migration and metastasis. In addition, Ape1/Ref-1 inhibitory activity is shown to augment the therapeutic effects of other therapeutics and protect normal cells against toxicity. Further, Ape1/Ref-1 inhibition is shown to decrease angiogenesis, for use in the treatment of cancer as well other pathologic conditions of which altered angiogenesis is a component.

Assignee: Indiana University Research and Technology Corporation (Indianapolis, IN)
Application Number:14/690,973
Patent Claims:1. A method for inhibiting a cancer selected from the group consisting of ovarian cancer and breast cancer associated with altered angiogenesis, the method comprising administering to a subject in need thereof an effective amount of 3-[(5-(2,3-dimethoxy-6-methyl 1,4-benzoquinoyl)]-2-nonyl-2-propenoic acid, a pharmaceutically acceptable salt or a pharmaceutically acceptable solvate thereof, which selectively inhibits the redox function of Ape1/Ref-1 and is effective to inhibit angiogenesis, and at least one additional therapeutic agent selected from the group consisting of melphalan, gemcitabine, cisplatin, and retinoic acid.

2. The method of claim 1 wherein the effective amount of 3-[(5-(2,3-dimethoxy-6-methyl 1,4-benzoquinoyl)]-2-nonyl-2-propenoic acid, a pharmaceutically acceptable salt or a pharmaceutically acceptable solvate thereof, is from about 10 .mu.M to about 100 .mu.M.

3. The method of claim 1 wherein the effective amount of 3-[(5-(2,3-dimethoxy-6-methyl 1,4-benzoquinoyl)]-2-nonyl-2-propenoic acid, a pharmaceutically acceptable salt or a pharmaceutically acceptable solvate thereof, is from about 40 .mu.M to about 60 .mu.M.

4. A method for inhibiting a cancer selected from the group consisting of ovarian cancer and breast cancer, the method comprising administering to a subject in need thereof an effective amount of 3-[(5-(2,3-dimethoxy-6-methyl 1,4-benzoquinoyl)]-2-nonyl-2-propenoic acid, a pharmaceutically acceptable salt or a pharmaceutically acceptable solvate thereof, which selectively inhibits the redox function of Ape1/Ref-1 and is effective to inhibit angiogenesis, and inhibits tumor cell growth and administering at least one additional therapeutic agent selected from the group consisting of melphalan, cisplatin, gemcitabine and retinoic acid to the subject.

5. The method of claim 4 wherein the effective amount of 3-[(5-(2,3-dimethoxy-6-methyl 1,4-benzoquinoyl)]-2-nonyl-2-propenoic acid, a pharmaceutically acceptable salt or a pharmaceutically acceptable solvate thereof, is from about 10 .mu.M to about 100 .mu.M.

6. The method of claim 4 wherein the effective amount of 3-[(5-(2,3-dimethoxy-6-methyl 1,4-benzoquinoyl)]-2-nonyl-2-propenoic acid, a pharmaceutically acceptable salt or a pharmaceutically acceptable solvate thereof, is from about 40 .mu.M to about 60 .mu.M.

7. A method for inhibiting a cancer selected from the group consisting of ovarian cancer and breast cancer associated with altered angiogenesis, the method comprising administering to a subject in need thereof an effective amount of 3-[(5-(2,3-dimethoxy-6-methyl 1,4-benzoquinoyl)]-2-nonyl-2-propenoic acid, a pharmaceutically acceptable salt or a pharmaceutically acceptable solvate thereof, which selectively inhibits the redox function of Ape1/Ref-1 and is effective to inhibit angiogenesis, in combination with bevacizumab.

8. The method of claim 7 wherein the effective amount of 3-[(5-(2,3-dimethoxy-6-methyl 1,4-benzoquinoyl)]-2-nonyl-2-propenoic acid, a pharmaceutically acceptable salt or a pharmaceutically acceptable solvate thereof, is from about 10 .mu.M to about 100 .mu.M.

9. The method of claim 7 wherein the effective amount of 3-[(5-(2,3-dimethoxy-6-methyl 1,4-benzoquinoyl)]-2-nonyl-2-propenoic acid, a pharmaceutically acceptable salt or a pharmaceutically acceptable solvate thereof, is from about 40 .mu.M to about 60 .mu.M.
