Abstract

The present invention provides compounds, compositions thereof, and methods of using the same.

First claim

We claim:

1. A conjugate comprising a MK2 kinase, having a cysteine residue, Cys140, wherein the Cys140 is covalently, and irreversibly, bonded to an inhibitor, such that inhibition of the kinase is maintained;
wherein said conjugate is of formula A:
Cys140-modifier-inhibitor moiety   A

wherein the inhibitor moiety is a moiety that binds in the active site of the MK2 kinase and comprises

wherein

is attached to the modifier; wherein

is an optionally substituted group selected from

a 3-8 membered saturated or partially unsaturated carbocyclic ring, a 4-7 membered heterocyclic ring having 1-2 heteroatoms independently selected from nitrogen, oxygen, or sulfur, a 5-6 membered monocyclic heteroaryl ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur, a 7-10 membered bicyclic saturated, partially unsaturated or aryl ring which is optionally bridged, an 8-10 membered bicyclic heteroaryl ring having 1-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur, or a 7-10 membered bicyclic saturated or partially unsaturated heterocyclic ring having 1-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur;
Y 1 is CR 2 or N;
q is 0-6;
each R 2 is independently —R, halogen, —OR, —SR, —CN, —NO 2 —SO 2 NR, —SO 2 R, —SOR, —C(O)R, —CO 2 R, —C(O)N(R) 2 , —NRC(O)R, —NRC(O)OR, —NRC(O)N(R) 2 , —NRSO_A, or —N(R) 2 ;
each R is independently hydrogen or an optionally substituted group selected from C 1-6 aliphatic, phenyl, a 3-8 membered saturated or partially unsaturated carbocyclic ring, a 4-7 membered heterocyclic ring having 1-2 heteroatoms independently selected from nitrogen, oxygen, or sulfur, or a 5-6 membered monocyclic heteroaryl ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur; or
two R groups on the same nitrogen are taken together with the nitrogen atom to which they are attached to form a 4-7 membered heterocyclic ring having 0-2 additional heteroatoms independently selected from nitrogen, oxygen, or sulfur, or a 4-7 membered heteroaryl ring having 0-4 additional heteroatoms independently selected from nitrogen, oxygen, or sulfur; and
T is a covalent bond, —O—, —S—, —N(R)—, —C(O)—, —OC(O)—, —C(O)O—, —C(O)N(R)—, —N(R)C(O)—, —N(R)C(O)N(R)—, —S(O)—, —SO 2 —, —SO 2 N(R)—, —N(R)SO 2 —, or —N(R)SO 2 N(R)—; and

the modifier is selected from:
