The present technology provides methods end medicaments useful for treating prostate cancer and breast cancer. Such methods include administering at least one of cyclo[Phe-D-Pro-Phe-Trp] and cyclo[Phe-D-Pro-Phe-D-Trp] to a subject suffering from prostate cancer or breast cancer.
1. A method comprising administering at least one of cyclo[Phe-D-Pro-Phe-Trp] and cyclo[Phe-D-Pro-Phe-D-Trp] or a pharmaceutically acceptable salt thereof to a subject suffering from prostate cancer or breast cancer.
2. The method of claim 1 , wherein the method comprises administering an effective amount of at least one of cyclo[Phe-D-Pro-Phe-Trp] and cyclo[Phe-D-Pro-Phe-D-Trp] or a pharmaceutically acceptable salt thereof to the subject, wherein the effective amount is effective in treating the prostate cancer or the breast cancer.
3. The method of claim 1 , wherein the prostate cancer comprises at least one oncogenic mutation found in a PC-3 cell line, a LNCaP cell line, a 22Rv1 cell line, a DU145 cell line, or a combination of any two or more thereof.
4. The method of claim 1 , wherein the breast cancer comprises triple negative breast cancer.
5. The method of claim 1 , wherein the breast cancer comprises at least one oncogenic mutation found in a BT-20 cell line, a MDA-MB-468 cell line, a MDA-MB-231 cell line, a MCF-7 cell line, a SKBR-3 cell line, a BT-474 cell ine, or a combination of any two or more thereof.
6. The method of claim 1 , wherein administering comprises oral administration or parenteral administration.
7. The method of claim 1 , wherein administering comprises at least one of subcutaneous administration, intravenous administration, and oral administration.
8. The method of claim 1 , wherein the method comprises administering cyclo[Phe-D-Pro-Phe-Trp] or a pharmaceutically acceptable salt thereof.
9. The method of claim 1 , wherein the method comprises administering cyclo[Phe-D-Pro-Phe-D-Trp] or a pharmaceutically acceptable salt thereof.
10. The method of claim 1 , wherein the method comprises administering a composition comprising at least one of cyclo[Phe-D-Pro-Phe-Trp] and cyclo[Phe-D-Pro-Phe-D-Trp] and a pharmaceutically acceptable carrier.
11. The method of claim 10 , wherein the composition is formulated for oral administration or parenteral administration.
12. The method of claim 10 , wherein the composition is formulated for at least one of subcutaneous administration and intravenous administration.
13. The method of claim 10 , wherein the pharmaceutically acceptable carrier comprises saline.
14. The method of claim 10 , wherein the pharmaceutically acceptable carrier comprises polyethylene glycol, a polyethylene glycol fatty acid monoester, a polyethoxylene sorbitan ester, or a combination of any two or more thereof.
15. The method of claim 10 , wherein the composition is a liquid formulation comprising about 0.1 mg/mL to about 50 mg/mL of the at least one of cyclo[Phe-D-Pro-Phe-Trp] and cyclo[Phe-D-Pro-Phe-D-Trp] or a pharmaceutically acceptable salt thereof.
16. The method of claim 1 , wherein the method comprises administering to the subject about 1 mg to about 150 mg of the at least one of cyclo[Phe-D-Pro-Phe-Trp] and cyclo[Phe-D-Pro-Phe-D-Trp] per kilogram of the subject.
17. The method of claim 1 , wherein the method comprises administering to the subject from about 1 to about 7 times per week.
18. The method of claim 2 , wherein the prostate cancer comprises at least one oncogenic mutation found in a PC-3 cell line, a LNCaP cell line, a 22Rv1 cell line, a DU145 cell line, or a combination of any two or more thereof.
19. The method of claim 2 , wherein the breast cancer comprises triple negative breast cancer.
20. The method of claim 2 , wherein the breast cancer comprises at least one oncogenic mutation found in a BT-20 cell line, a MDA-MB-468 cell line, a MDA-MB-231 cell line, a MCF-7 cell line, a SKBR-3 cell line, a BT-474 cell line, or a combination of any two or more thereof.
