Claims

1-21. -21. (canceled)

22. A method of inhibiting Btk activity comprising administering a selective, covalent, Btk inhibitor, wherein the selective, covalent, Btk inhibitor selectively and covalently bonds to Bruton'"'"'s tyrosine kinase (Btk).

33. The method of claim 22, wherein the Btk inhibitor bonds to Bruton'"'"'s tyrosine kinase (Btk) irreversibly.

35. The method of claim 22 wherein the covalent bond is formed between a portion of a Michael acceptor moiety on the inhibitor and a portion of a cysteine residue of a Bruton'"'"'s tyrosine kinase (Btk).

36. The method of claim 35, wherein the Michael acceptor moiety is an acrylamide, vinyl sulfonamide or propargylamide.

37. The method of claim 35, wherein the covalent bond is formed from a functional group on the Btk inhibitor and wherein the functional group is capable of covalently binding a cysteine residue of a Bruton'"'"'s tyrosine kinase (Btk).

23. A method for inhibiting Btk activity comprising administering a Btk inhibitor, wherein the Btk inhibitor is a covalent drug that targets a cysteine residue of Bruton'"'"'s tyrosine kinase (Btk).

34. The method of claim 23, wherein the Btk inhibitor forms a covalent bond to Bruton'"'"'s tyrosine kinase (Btk).
