Details for Patent: 9,133,198

Title:Inhibitors of bruton'S tyrosine kinase
Abstract: Disclosed herein are compounds of Formula (A) 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. ##STR00001##
Inventor(s): Honigberg; Lee (San Francisco, CA), Verner; Erik (Belmont, CA), Pan; Zhengying (Austin, TX)
Assignee: PHARMACYCLICS LLC (Sunnyvale, CA)
Filing Date:May 09, 2013
Application Number:13/890,498
Claims:1. A method for treating acute lymphoblastic leukemia (ALL) in an individual comprising administering to a subject in need thereof a therapeutically effective amount an irreversible covalent Btk inhibitor having the structure of Formula (A): ##STR00058## wherein A is N; R.sub.1 is L.sub.2-(substituted or unsubstituted heteroaryl) or L.sub.2-(substituted or unsubstituted aryl), 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.6alkyl), or -(substituted or unsubstituted C.sub.2-C.sub.6-alkenyl); 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 alkyl, optionally substituted or unsubstituted cycloalkyl, optionally substituted or unsubstituted alkenyl, or optionally substituted or unsubstituted alkynyl; 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--, heteroaryl, aryl, --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 alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, or substituted or unsubstituted heterocycle; 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 each independently H; 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 each R.sub.11 is independently selected from H, --S(.dbd.O).sub.2R.sub.8, --S(.dbd.O).sub.2NH.sub.2, --C(O)R.sub.8, --CN, --NO.sub.2, heteroaryl, or heteroalkyl; or a pharmaceutically acceptable solvate, hydrate, or salt thereof.

2. The method of claim 1, wherein the inhibitor of Btk is administered orally.

3. The method of claim 1, wherein the inhibitor forms a covalent bond to a cysteine sidechain of a Bruton's tyrosine kinase (Btk).

4. The method of claim 3, wherein the cysteine sidechain of the Btk is the sidechain of cysteine 481.

5. The method of claim 1, wherein the inhibitor is a compound having the structure: ##STR00060##

6. A method for treating acute lymphoblastic leukemia (ALL) in an individual comprising administering to the individual in need thereof an inhibitor of Bruton's tyrosine kinase (Btk), having the structure: ##STR00061## or a pharmaceutically acceptable salt thereof.

7. The method of claim 1 wherein R.sub.1 is L.sub.2-substituted or unsubstituted aryl.

8. The method of claim 7 wherein L.sub.2 is a bond.

9. The method of claim 8 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 ##STR00062##
