OVA-E1 peptide TFA, is an antagonist variant of SIINFEKL [OVA (257-264). OVA-E1 peptide, activates the p38 and JNK cascades similarly in mutant and wild-type thymocytes.

p38α inhibitor 2 is a highly potent and selective p38α MAPK inhibitor, with a pIC50 of 9.6. p38α inhibitor 2 inhibits the hERG ion channel (IC50=27 μM) and shows a promising selectivity profile when tested in a panel of 51 other protein kinases (<30% inhibition at 10 μM concentration) and a panel of 141 other biological targets.

(E)-Osmundacetone is the isomer of Osmundacetone. Osmundacetone significantly suppresses the phosphorylation of MAPKs, including JNK, ERK, and p38 kinases. Osmundacetone has a neuroprotective effect against oxidative stress.

Andrograpanin, a bioactive compound from Andrographis paniculata, exhibits anti-inflammatory and anti-infectious properties.

Gypenoside L is a saponin that can be found in Gynostemma pentaphyllum. Gypenoside L increases the SA-β-galactosidase activity, promotes the production of senescence-associated secretory cytokines. Gypenoside L also can activate p38 and ERK MAPK pathways and NF-κB pathway to induce senescence. Gypenoside L exhibits anti-tumor and anti-inflammatory activities.

AMG-548 hydrochloride, an orally active and selective p38α inhibitor (Ki=0.5 nM), shows slightly selective over p38β (Ki=36 nM) and >1000 fold selective against p38γ and p38δ. AMG-548 hydrochloride is also extremely potent in the inhibition of whole blood LPS stimulated TNFα (IC50=3 nM). AMG-548 hydrochloride inhibits Wnt signaling by directly inhibiting Casein kinase 1 isoforms δ and ε.

SKF-86002 dihydrochloride is an orally active p38 MAPK inhibitor, with anti-inflammatory, anti-arthritic and analgesic activities. SKF-86002 dihydrochloride inhibits lipopolysaccharide (LPS)-stimulate human monocyte IL-1 and TNF-α production (IC50 = 1 μM). SKF-86002 dihydrochloride inhibits lipoxygenase- and cyclooxygenase-mediated metabolism of arachidonic acid.

Anti-inflammatory agent 7 inhibits proinflammatory cytokines by blocking the NF-κB/MAPK signaling pathway in LPS-treated RAW 264.7 cells as well as mice.

Ganoderterpene A attenuates LPS-induced inflammation and apoptosis via suppressing MAPK and TLR-4/NF-κB pathways in BV-2 cells.

Emprumapimod is a potent, orally bioavailable and selective inhibitor of p38α MAPK directly inhibits LPS-induced IL-6 production from RPMI-8226 cell (IC50=100 pM). Emprumapimod can be used for the research of dilated cardiomyopathy and acute inflammatory pain.

EO 1428 is a highly specific inhibitor of p38 of the aminobenzophenone class. EO 1428 (1 μM ) markedly attenuates LPS-induced tumor necrosis factor α-converting enzyme (TACE) activity up-regulation.

18:0-22:6 DG (1-Stearoyl-2-docosahexaenoyl-sn-glycerol) is a diacylglycerol that can bind to RasGRP and modulate MAP kinases activation.

SB 706504 is a potent p38 MAPK inhibitor that inhibits Lipopolysaccharides-stimulated inflammatory gene expression in macrophages in chronic obstructive pulmonary disease (COPD).

DCZ19931 is a novel multi-targeting kinase inhibitor, exhibits anti-angiogenic effects in vitro and inhibits ocular neovascularization in vivo.

Non-canonical p38α inhibitor NC-37 (NC-p38i NC-37) is a potent, highly selective, non-canonical inhibitor of p38α, inhibits TAB1-induced p38α autophosphorylation in vitro with IC50 of 0.27 uM.

Non-canonical p38α inhibitor NC-38 (NC-p38i NC-38) is a potent, highly selective, non-canonical inhibitor of p38α, inhibits TAB1-induced p38α autophosphorylation in vitro with IC50 of 0.27 uM.

NuP-3 is a potent, selective MAPK13 and MAPK14 inhibitor with IC50 of 7 and 14 nM, respectively.
