mk2 phosphorylation

CC-99677 (Gamcemetinib) is a selectively targeted covalent MAPKAPK2 (MK2) inhibitor for autoimmune diseases that translates biochemical potency into cellular potency as demonstrated by potent inhibition of heat shock protein 27 (HSP1) phosphorylation in LPS-activated monocyte THP-27 cells via a nucleophilic aromatic substitution (SNAr) mechanism.CC-99677 in Rat experiments demonstrated potency in both biochemical (IC 50 =156.3 nM) and cellular assays (EC 50 =89 nM).

Ralimetinib selectively inhibits phosphorylation of MK2 (Thr334) and has no effect on phosphorylation of p38α MAPK, JNK, ERK1 2, c-Jun, ATF2, or c-Myc. Ralimetinib is an effective and selective, ATP-competitive inhibitor of p38 MAPK α β (IC50s: 5.3 and 3.

Potent and selective p38α and p38β degrader (DC50 < 50 nM). Displays no significant degradation of p38γ, p38δ, JNK1/2 or ERK1/2. Inhibits phosphorylation of MK2 in UV-treated cancer cells and LPS-stimulated bone marrow-derived macrophages (BMDM). Exhibits similar effect to p38α gene knockout in BBL358 cells. Active in vivo.

MW-150 hydrochloride (MW01-18-150SRM hydrochloride) is a potent and selective inhibitor of p38α MAPK with a Ki value of 101 nM. It exhibits excellent CNS penetration and oral bioavailability, and effectively suppresses the phosphorylation of MK2, a substrate of endogenous p38α MAPK, in activated glial cells.

CMPD1 is a non-ATP-competitive p38 MAPK-mediated MK2 phosphorylation inhibitor(apparent Ki (Kiapp): 330 nM).

MK2-IN-5, a pseudosubstrate of Mk2 with an inhibition constant (K_i) of 8 μM, selectively targets the protein interaction domain of the MAPK pathway and inhibits the phosphorylation of HSP25 and HSP27 [1] [2] [3].

(R)-STU104 is a novel TAK1-MKK3 protein-protein interaction (PPI) inhibitor that inhibits TNF-α and suppresses the TAK1 MKK3 p38 MnK1 MK2 elF4E signalling pathway by binding to MKK3 and disrupting TAK1 phosphorylation of MKK3. (R)-STU104 is a candidate compound for the treatment of ulcerative colitis.
