Abstract

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

Claims (32)

1. 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; and

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.

2. The compound according to claim 1 wherein the compound is selected from:

or a pharmaceutically acceptable salt thereof.

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

4. The composition according to claim 3 , further comprising an additional therapeutic agent.

5. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein Hy is a 5-membered heteroaryl ring having 1-2 nitrogens.

6. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein Hy is pyrazolyl, imidazolyl, pyridinyl, or pyrazinyl.

7. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein R 1 is optionally substituted C 1-6 aliphatic.

8. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein R 1 is unsubstituted C 1-6 aliphatic.

9. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein R 1 is —CH 3 .

10. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein p is 1.

11. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein

12. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein L 2 is

13. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein R x is hydrogen.

14. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein

15. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein R 2 is hydrogen.

16. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein L 1 is a covalent bond.

17. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein Ring B is phenyl.

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

19. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein Ring B is

20. The compound according to claim 1 , or a pharmaceutically acceptable salt thereof, wherein R 3 is hydrogen.
