Deacetylnemorone abietane diterpenoids for use in cancer treatment
A deacetylnemorone abietane diterpenoid is utilized in the prevention of growth and development of pathogenic cells, e.g., cancer cells. The deacetylnemorone can have the following structure: or a tautomer there of in which R 1 , R 2 , and R 3 are independently selected from —H, C 1-10 alkyl, C 1-10 alkoxy, C 1-10 alkenyl, C 1-10 alkenoxy, —OH, —OAc, —CHO, -Ph, —OC 6 H 5 , —OC 6 H 4 OH, —COC 6 H 5 , —OCONH 2 , —OCONHCH 3 , —OCOC 6 H 4 NH 2 , —NH 2 , or ═O. The deacetylnemorone shows efficacy in treatment and prevention of a wide range of cancer types as well as other neoplastic diseases as a chemo-preventative, a primary or secondary cytotoxic agent, a sensitizer for other therapies, or one component of a combinatorial treatment.
1. A method for inhibiting growth and development of cancer cells, the method comprising delivering a deacetylnemorone abietane diterpenoid to an area comprising cancer cells, the cancer cells comprising breast cancer cells, ovarian cancer cells, melanoma cells, colon cancer cells, or osteosarcoma cells, the deacetylnemorone abietane diterpenoid having a structure of:
2. The method of claim 1 , wherein the deacetylnemorone is delivered to the cancer cells such that the deacetylnemorone contacts the cancer cells at a concentration of about 10 millimolar or greater.
3. The method of claim 1 , wherein the deacetylnemorone is delivered to the cancer cells such that the deacetylnemorone contacts the cancer cells at a concentration of from about 10 millimolar to about 50 millimolar.
4. The method of claim 1 , wherein the deacetylnemorone is delivered to the area in multiple doses.
5. The method of claim 1 , the method comprising delivering the deacetylnemorone to the cancer cells in conjunction with a second bioactive agent.
6. The method of claim 5 , the method comprising delivering the deacetylnemorone and the second bioactive agent to the cancer cells together in a single composition.
7. The method of claim 5 , the method comprising delivering the deacetylnemorone separately from the delivery of the second bioactive agent to the area.
8. The method of claim 5 , wherein the second bioactive agent comprises a chemotherapy agent.
9. The method of claim 8 , wherein the chemotherapy agent comprises 5-fluoro-2′-deoxyuridine.
10. The method of claim 1 , wherein the cancer cells are resistant to one or more chemotherapy agents.
11. The method of claim 1 , wherein the cancer cells comprise breast cancer cells.
12. The method of claim 1 , wherein the cancer cells comprise ovarian cancer cells.
13. The method of claim 1 , wherein the cancer cells comprise melanoma cells.
14. The method of claim 1 , wherein the cancer cells comprise colon cancer cells.
