INHIBITORS OF BRUTON'S TYROSINE KINASE
Described herein are irreversible kinase inhibitor compounds, methods for synthesizing such irreversible inhibitors, and methods for using such irreversible inhibitors in the treatment of diseases. Further described herein are methods, assays and systems for determining an appropriate irreversible inhibitor of a protein, including a kinase.
1 .- 100 . (canceled)
101 . An inhibited tyrosine kinase comprising an irreversible Tec kinase inhibitor having a covalent bond to a cysteine residue of a Tec kinase.
102 . The inhibited tyrosine kinase of claim 101 , 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 the Tec kinase.
103 . The inhibited tyrosine kinase of claim 102 , wherein the Michael acceptor moiety is an acrylamide, vinyl sulfonamide or propargylamide.
104 . The inhibited tyrosine kinase of claim 101 , wherein the Tec kinase is activated.
105 . The inhibited tyrosine kinase of claim 101 , wherein the inhibited Tec kinase has the structure:
wherein:
L a is O or S;
Ar is an unsubstituted phenyl;
Y is a 4-, 5-, 6-, or 7-membered cycloalkyl ring, or
Y is azetidinyl, pyrrolidinyl, piperidinyl, or azepanyl;
