Abstract

The present invention provides compounds useful as modulators, agonists or antagonists of androgen receptor (AR), compositions thereof, and methods of making and using the same.

First claim

We claim:

1. A compound of formula I:

or a pharmaceutically acceptable salt thereof, wherein:
X is N; and
Z is —CH 2 — or Ring B; and
Ring B is a 5 or 7-14 membered saturated or partially unsaturated carbocyclic monocyclic or bicyclic ring substituted with n instances of R b , wherein said ring is spiro-fused at point Z;
n is 0 to 4;
each R b is independently substituted or unsubstituted C 1-6 aliphatic.

2. The compound of claim 1 of formula II:

or a pharmaceutically acceptable salt thereof.

3. The compound of claim 1 of formula III:

or a pharmaceutically acceptable salt thereof.

4. The compound according to claim 1 , wherein the compound is:

5. A pharmaceutical composition comprising a compound according to claim 1 , or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier, adjuvant, or vehicle.

6. A method of treating a cancer or another proliferative disease, disorder or condition, comprising administering to a patient in need thereof a compound according to claim 1 .

7. The method of claim 6 , wherein the cancer is a castration-resistant prostate cancer.

8. The method of claim 7 , wherein the castration-resistant prostate cancer bears one or more mutations in the androgen receptor.

9. The method of claim 8 , wherein the one or more mutations in the androgen receptor comprises a mutation of Phe876.

10. The method of claim 9 , wherein the mutation is Phe876 to Leu, Ile, Val, Ser, Cys, or Tyr.

11. The method of claim 9 , wherein the mutations further comprise one or more mutations to residues selected from the group consisting of E566, E589, E669, C687, A700, N772, H777, C785, F877, and K911.

12. The method of claim 7 , wherein the castration-resistant prostate cancer is resistant to Enzalutamide.

13. The compound of claim 1 , wherein the compound is:

14. The compound of claim 1 , wherein the compound is:

15. The compound of claim 1 , wherein the compound is:

16. The compound of claim 1 , wherein the compound is:

17. A method of preparing a compound of formula I:

or a pharmaceutically acceptable salt thereof, wherein:
X is N; and
Z is —CH 2 — or Ring B; and
Ring B is a 5 or 7-14 membered saturated or partially unsaturated carbocyclic monocyclic or bicyclic ring substituted with n instances of R b , wherein said ring is spiro-fused at point Z;
n is 0 to 4; and
each R b is independently substituted or unsubstituted C 1-6 aliphatic;
the method comprising a step of reacting one of a 5-amino-2-cyano-3-trifluoromethylpyridine or a 4-amino-2-(trifluoromethyl)benzonitrile with a N-methyl-4-(1-cyanocycloalkylamino)-2-fluorobenzamide in the presence of thiophosgene.

18. A method of manufacturing a pharmaceutical composition comprising formulating a compound of formula I with a pharmaceutically acceptable carrier, adjuvant, or vehicle, wherein the compound of formula I is represented by the following structural formula:

or a pharmaceutically acceptable salt thereof, wherein:
X is N; and
Z is —CH 2 — or Ring B; and
Ring B is a 5 or 7-14 membered saturated or partially unsaturated carbocyclic monocyclic or bicyclic ring substituted with n instances of R b , wherein said ring is spiro-fused at point Z;
n is 0 to 4; and
each R b is independently substituted or unsubstituted C 1-6 aliphatic.
