Abstract

The present invention provides compounds useful as inhibitors of AHR, compositions thereof, and methods of using the same.

Claims (36)

1. A method for treating a cancer in a patient in need thereof, comprising administering to said patient a compound of formula IV-g:

or a pharmaceutically acceptable salt thereof, wherein:

Hy is a 5-6 membered heteroaryl ring having 1-2 nitrogens;

L 2 is

each R x is independently hydrogen or C 1-4 alkyl;

Ring B is phenyl or a 5-6 membered monocyclic heteroaromatic ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur;

each R 1 is independently hydrogen, deuterium, or optionally substituted C 1-6 aliphatic;

each R is independently hydrogen, deuterium, or optionally substituted C 1-6 aliphatic;

L 1 is a covalent bond;

each of R 2 and R 3 is independently selected from R, halogen, cyano, nitro, and —OR;

each of m and n is independently 1, 2, 3, 4, or 5; and

p is 0, 1, 2, or 3,

wherein the cancer is selected from bladder cancer, breast cancer, gastric cancer, glioma, glioblastoma, ovarian cancer, head and neck cancer, lung cancer, kidney cancer, lymphoma, prostate cancer, stomach cancer, esophageal cancer, and acute myeloid leukemia (AML).

2. The method according to claim 1 , further comprising administering to said patient an additional chemotherapeutic agent.

3. The method according to claim 1 , wherein the compound is administered orally.

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

or a pharmaceutically acceptable salt thereof.

5. The method according to claim 1 , wherein Hy is a 5-membered heteroaryl ring having 1-2 nitrogens.

6. The method according to claim 1 , wherein Hy is pyrazolyl, imidazolyl, pyridinyl, or pyrazinyl.

7. The method according to claim 1 , wherein R 1 is optionally substituted C 1-6 aliphatic.

8. The method according to claim 1 , wherein R 1 is unsubstituted C 1-6 aliphatic.

9. The method according to claim 1 , wherein R 1 is —CH 3 .

10. The method according to claim 1 , wherein p is 1.

11. The method according to claim 1 , wherein

12. The method according to claim 1 , wherein L 2 is

13. The method according to claim 1 , wherein R x is hydrogen.

14. The method according to claim 1 , wherein

15. The method according to claim 1 , wherein R 2 is hydrogen.

16. The method according to claim 1 , wherein L 1 is a covalent bond.

17. The method according to claim 1 , wherein Ring B is phenyl.

18. The method according to claim 1 , wherein Ring B is a 5-6 membered monocyclic heteroaromatic ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur.

19. The method according to claim 1 , wherein Ring B is

20. The method according to claim 1 , wherein R 3 is hydrogen.

21. The method according to claim 1 , wherein R 3 is optionally substituted C 1-6 aliphatic.

22. The method according to claim 1 , wherein R 3 is —OR.

23. The method according to claim 1 , wherein R 3 is halogen.
