Piperidin-4-yl azetidine derivatives as JAK1 inhibitors
The present invention provides piperidin-4-yl azetidine derivatives, as well as their compositions and methods of use, that modulate the activity of Janus kinase 1 (JAK1) and are useful in the treatment of diseases related to the activity of JAK1 including, for example, inflammatory disorders, autoimmune disorders, cancer, and other diseases.
1. A method of ameliorating or inhibiting a skin disorder in a patient in need thereof, comprising administering to said patient a therapeutically effective amount of a compound, which is {1-{1-[3-fluoro-2-(trifluoromethyl)isonicotinoyl]piperidin-4-yl}-3-[4-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-3-yl}acetonitrile, or a pharmaceutically acceptable salt thereof, wherein said skin disorder is selected from atopic dermatitis, skin sensitization, skin irritation, skin rash, contact dermatitis, and allergic contact sensitization.
2. The method of claim 1 , wherein said pharmaceutically acceptable salt is {1-{1-[3-fluoro-2-(trifluoromethyl)isonicotinoyl]piperidin-4-yl}-3-[4-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-3-yl}acetonitrile adipic acid salt.
3. The method of claim 1 , wherein the skin disorder is atopic dermatitis.
4. The method of claim 1 , wherein the skin disorder is skin sensitization.
5. The method of claim 1 , wherein the skin disorder is skin irritation.
6. The method of claim 1 , wherein the skin disorder is skin rash.
7. The method of claim 1 , wherein the skin disorder is contact dermatitis.
8. The method of claim 1 , wherein the skin disorder is allergic contact sensitization.
9. The method of claim 2 , wherein the skin disorder is atopic dermatitis.
10. The method of claim 2 , wherein the skin disorder is skin sensitization.
11. The method of claim 2 , wherein the skin disorder is skin irritation.
12. The method of claim 2 , wherein the skin disorder is skin rash.
13. The method of claim 2 , wherein the skin disorder is contact dermatitis.
14. The method of claim 2 , wherein the skin disorder is allergic contact sensitization.
