Abstract

The present invention provides mito-magnolol compounds, pharmaceutical compositions thereof, and methods of using the mito-magnolol compounds in the treatment of cancer, especially anti-cancer therapy or kinase resistant cancers.

First claim

We claim:

1. A mito-magnolol compound of:

wherein n is an integer selected from 1-18, or

wherein n is an integer selected from 1-18.

2. A composition comprising the mito-magnolol compound of claim 1 and a pharmaceutically acceptable carrier.

3. A method of treating cancer in a subject having cancer comprising:
administering the mito-magnolol compound of claim 1 in a therapeutically effective amount to treat the cancer, wherein the cancer is melanoma.

4. The method of claim 3 , wherein the cancer is resistant to anti-cancer therapy.

5. The method of claim 4 , wherein the anti-cancer therapy is a BRAF inhibitor.

6. The method of claim 4 , wherein the anti-cancer therapy is a checkpoint inhibitor.

7. The method of claim 3 , wherein the mito-magnolol compound is administered in combination with one or more additional anti-cancer therapies.

8. The method of claim 7 , wherein the anti-cancer therapy is a BRAF inhibitor.

9. A method of reducing or inhibiting melanoma cancer cell growth in a subject having cancer, the method comprising:
administering the mito-magnolol compound of claim 1 in a therapeutically effective amount to reduce or inhibit melanoma cancer cell growth.

10. The method of claim 9 , wherein the mito-magnolol compound is administered in combination with one or more anti-cancer therapies.

11. A method of preventing or delaying resistance of a melanoma cancer to an anti-cancer therapy in a subject, the method comprising:
administering the mito-magnolol compound of claim 1 in a therapeutically effective amount to prevent or delay resistance of the melanoma cancer to the anti-cancer therapy.

12. The method of claim 11 , wherein the mito-magnolol compound is administered in combination with an anti-cancer therapy.

13. The method of claim 12 , wherein the anti-cancer therapy is co-currently administered.

14. A method of increasing a T cell response to an anti-cancer therapy in a cancer patient, the method comprising administering the mito-magnolol compound of claim 1 in a therapeutically effective amount to increase the T cell response to the anti-cancer therapy, wherein the cancer is melanoma.

15. The method of claim 14 , wherein the anti-cancer therapy is an inhibitor of an oncogenic kinase.

16. The method of claim 14 , wherein the anti-cancer therapy is a checkpoint inhibitor.

17. The method of claim 14 , wherein the mito-magnolol compound is administered in combination with one or more anti-cancer therapies.

18. A kit comprising at least one mito-magnolol compound of claim 1 , a pharmaceutically acceptable carrier or diluent, and instructional material.
