Abstract

The present invention is directed to a method treating prostate cancer. The method comprises administering to a patient in need thereof at least one compound selected from N-methyl-Δ3,3′-dihydroindole-2,2′ diketone; N-1-(β-D-O-triacetyl-xylopranosyl)-Δ3,3′-dihydroindole-2,2′ diketone; and N-1-(β-D-O-triacetyl-xylopranosyl)-N′-methyl-Δ3,3′-dihydroindole-2,2′ diketone. Preferably the compound is in an amount sufficient to inhibit growth, invasion, and/or metastasis of prostate cancer cells.

Claims

1. A method of treating advanced stage prostate cancer, the method comprising administering a compound to a patient in need thereof, wherein the prostate cancer is hormone refractory and/or metastatic and the compound is selected from the group consisting of:

2. The method of claim 1, wherein the prostate cancer is androgen independent and metastatic prostate cancer and the compound is administered in a pharmaceutical composition comprising a pharmaceutical acceptable carrier.

3. The method of claim 1, wherein the compound is in an amount to induce apoptosis of androgen independent cancer cells.

4. The method of claim 1, wherein the patient is human.

5. The method of claim 4, wherein the compound is in an amount sufficient to inhibit at least 30% of invasive cells.

6. The method of claim 5, wherein at least 60% of the invasive cells are inhibited.

7. The method of claim 1, wherein the compound is administered in combination with paclitaxel.

8. The method of claim 1, wherein the compound is administered in combination with dexamethasone.

9. The method of claim 1, wherein the compound is administered in combination with a chemotherapeutic agent, a protein kinase inhibitor, a topoisomerase inhibitor, a mitotic kinesin inhibitor, a histone deacetylase inhibitor, a mTOR inhibitor, a growth factor inhibitor, a growth factor receptor inhibitor, a transcriptional factor inhibitor, an anticancer monoclonal antibody, and/or glucocorticoid hormones.

10. The method of claim 9, wherein the chemotherapeutic agent is selected from the group consisting of:

an alkylating agents, anti-metabolitic agents, antibiotics, anti-tubule agents, and anti-hormonal agents.

11. The method of claim 9, wherein the protein kinase inhibitor inhibits at least one of the following:

cyclin-dependent kinases, tyrosine kinases, phosphoinositide 3-kinase PI3K/AKT, protein kinase C, casein kinases, MAP kinases, or Src kinases.

12. The method of claim 1, wherein the compound is administered orally.

13. The method of claim 1, wherein the compound is administered parenterally.

14. The method of claim 13, wherein the compound is administered subcutaneously, intravenously, intramuscularly, or intra-arterially.

15. The method of claim 14, wherein the compound is administered to a human patient, in an amount of about 0.5 mg to 5 mg per kilogram of body weight.

16. The method of claim 1, wherein compound is in a dosage unit forms containing between from about 10 mg to about 240 mg of the compound per day.

17. A method of treating advanced stage prostate cancer, the method comprising administering to a patient having hormone refractory and/or metastatic prostate cancer a compound selected from the group consisting of:
