Small molecule androgen receptor inhibitors and methods of use thereof
Small molecule carbazole compounds for use as androgen receptor inhibitors are provided herein. Also provided herein are methods for using the carbazole compounds in treating prostate cancer, including castration-resistant prostate cancer and enzalutamide-resistant prostate cancer. The methods include administering to a subject an effective amount of a compound or composition as described herein.
1. A compound selected from the group consisting of:
or a pharmaceutically acceptable salt thereof.
2. A composition comprising a compound of claim 1 and a pharmaceutically acceptable carrier.
3. A method of treating prostate cancer in a subject, comprising administering to the subject an effective amount of the composition of claim 2 .
4. The method of claim 3 , wherein the prostate cancer is a castration-resistant prostate cancer or a drug-resistant cancer.
5. The method of claim 3 , wherein the prostate cancer is androgen-independent prostate cancer or androgen-dependent prostate cancer.
6. The method of claim 3 , further comprising administering a second therapeutic agent to the subject, wherein the second therapeutic agent is a chemotherapeutic agent.
7. A method of inhibiting androgen receptor activity in a cell, comprising contacting the cell with an effective amount of the compound of claim 1 .
8. The method of claim 7 , wherein the cell is an androgen-dependent cell or an androgen-independent cell.
9. The method of claim 7 , wherein the contacting is performed in vivo.
10. The method of claim 7 , wherein the contacting is performed in vitro.
