Title: | Inhibitors of Bruton's tyrosine kinase |
Abstract: | Disclosed herein are compounds, including compounds having the structure of Formula (A), (B), (C), and (D), as described in further detail herein, that form covalent bonds with Bruton's tyrosine kinase (Btk). Also described are irreversible inhibitors of Btk. Methods for the preparation of the compounds are disclosed. Also disclosed are pharmaceutical compositions that include the compounds. Methods of using the Btk inhibitors are disclosed, alone or in combination with other therapeutic agents, for the treatment of autoimmune diseases or conditions, heteroimmune diseases or conditions, cancer, including lymphoma, and inflammatory diseases or conditions. |

Claims: | 1. A method for treating a disease selected from asthma, arthritis, rheumatoid arthritis, or lupus comprising administering to a subject in need thereof an irreversible inhibitor of Bruton's tyrosine kinase (Btk), wherein the inhibitor is a compound having the structure of Formula (A) ##STR00058## wherein: A is independently selected from N; R.sub.1 is L.sub.2-(substituted or unsubstituted heteroaryl), or L.sub.2-(substituted or unsubstituted arylene), where L.sub.2 is a bond, O, S, --S(.dbd.O), --S(.dbd.O).sub.2, C(.dbd.O), -(substituted or unsubstituted C.sub.1-C.sub.6 alkylene), or -(substituted or unsubstituted C.sub.2-C.sub.6 alkenylene); R.sub.2 and R.sub.3 are independently selected from H or lower alkyl; R.sub.4 is L.sub.3-X-L.sub.4-G, wherein, L.sub.3 is optional, and when present is a bond, optionally substituted or unsubstituted alkylene, optionally substituted or unsubstituted cycloalkylene, optionally substituted or unsubstituted alkenylene, or optionally substituted or unsubstituted alkynylene; X is optional, and when present is a bond, O, --C(.dbd.O), S, --S(.dbd.O), --S(.dbd.O).sub.2, --NH, --NR.sub.9, --NHC(O), --C(O)NH, --NR.sub.9C(O), --C(O)NR.sub.9, --S(.dbd.O).sub.2NH, --NHS(.dbd.O).sub.2, --S(.dbd.O).sub.2NR.sub.9--, --NR.sub.9S(.dbd.O).sub.2, --OC(O)NH--, --NHC(O)O--, --OC(O)NR.sub.9--, --NR.sub.9C(O)O--, --CH.dbd.NO--, --ON.dbd.CH--, --NR.sub.10C(O)NR.sub.10--, heteroarylene, arylene, --NR.sub.10C(.dbd.NR.sub.11)NR.sub.10--, --NR.sub.10C(.dbd.NR.sub.11)--, --C(.dbd.NR.sub.11)NR.sub.10--, --OC(.dbd.NR.sub.11)--, or --C(.dbd.NR.sub.11)O--; L.sub.4 is optional, and when present is a bond, substituted or unsubstituted alkylene, substituted or unsubstituted cycloalkylene, substituted or unsubstituted alkenylene, substituted or unsubstituted alkynylene, substituted or unsubstituted arylene, substituted or unsubstituted heteroarylene, or substituted or unsubstituted heterocyclene; or L.sub.3, X and L.sub.4 taken together form a nitrogen containing heterocyclic ring; G is ##STR00059## wherein, R.sub.6, R.sub.7 and R.sub.8 are independently selected from among H, lower alkyl or substituted lower alkyl, lower heteroalkyl or substituted lower heteroalkyl, substituted or unsubstituted lower cycloalkyl, and substituted or unsubstituted lower heterocycloalkyl; R.sub.9 is selected from among H, substituted or unsubstituted lower alkyl, and substituted or unsubstituted lower cycloalkyl; each R.sub.10 is independently H, substituted or unsubstituted lower alkyl, or substituted or unsubstituted lower cycloalkyl; or two R.sub.10 groups can together form a 5-, 6-, 7-, or 8-membered heterocyclic ring; or R.sub.10 and R.sub.11 can together form a 5-, 6-, 7-, or 8-membered heterocyclic ring; or R.sub.11 is selected from H, --S(.dbd.O).sub.2R.sub.8, --S(.dbd.O).sub.2NH.sub.2, --C(O)R.sub.8, --NO.sub.2, heteroaryl, or heteroalkyl; or a pharmaceutically acceptable solvate, hydrate, or salt thereof. 2. The method of claim 1, wherein the disease is asthma. 3. The method of claim 1, wherein the disease is arthritis. 4. The method of claim 1, wherein the disease is rheumatoid arthritis. 5. The method of claim 1, wherein the disease is lupus. 6. The method of claim 1, wherein the inhibitor of Btk is administered orally. 7. The method of claim 1 wherein R.sub.2 and R.sub.3 are each independently H. 8. The method of claim 1 wherein R.sub.1 is a substituted phenyl. 9. The method of claim 1 wherein L.sub.3, X and L.sub.4 taken together form a nitrogen containing heterocyclic ring. 10. The method of claim 9 wherein G is ##STR00060## 11. The method of claim 1 wherein R.sub.6, R.sub.7, and R.sub.8 are each independently H. 12. The method of claim 1 wherein the compound has the structure ##STR00061## 13. A method for treating a disease selected from asthma, arthritis, rheumatoid arthritis, or lupus comprising administering to a subject in need thereof an irreversible inhibitor of Bruton's tyrosine kinase (Btk), wherein the inhibitor is a compound having the structure of ##STR00062## or a pharmaceutically acceptable solvate, hydrate, or salt thereof. |
