The p38-MAPK Inhibitor, SB203580, Inhibits Cardiac Stress-Activated Protein Kinases/c-Jun N-Terminal Kinases (SAPKs/JNKs)

FEBS Letters, 1998
SB203580 is a recognised inhibitor of p38-MAPKs. Here, we investigated the effects of SB203580 on cardiac SAPKs/JNKs. The IC50 for inhibition of p38-MAPK stimulation of MAPKAPK2 was approximately 0.07 microM, whereas that for total SAPK/JNK activity was ...

SB203580 inhibits epithelial–mesenchymal transition and pulmonary fibrosis in a rat silicosis model

Toxicology Letters, 2016
To investigate the role of p38 MAPK in silicosis, we explored the effects of SB203580 as a specific inhibitor of p38 MAPK in the silicosis model in rats. Rats were exposed to 50mg/ml silica intratracheally. From the first day after instillation, rats were injected with SB203580 1mg/kg/d.

Tri-substituted imidazole analogues of SB203580 as inducers for cardiomyogenesis of human embryonic stem cells

Bioorganic & Medicinal Chemistry Letters, 2013
The p38α mitogen-activated protein kinase (MAPK) inhibitor SB203580 had been reported to enhance the cardiomyogenesis of human embryonic stem cells (hESCs). To investigate if tri-substituted imidazole analogues of SB203580 are equally effective inducers for cardiomyogenesis of hESCs, and if there is a correlation between p38α MAPK inhibition and ...

p38 Inhibitor SB203580 Sensitizes the Resveratrol-Induced Apoptosis in Human Lung Adenocarcinoma (A549) Cells

Journal of Biochemical and Molecular Toxicology, 2012
AbstractBased on our recent findings that resveratrol, a natural plant polyphenol found in red grape skins as well as other food products, induces apoptosis via a caspase‐independent intrinsic pathway in human lung adenocarcinoma cells, this study is designed to explore whether SB203580, a p38 inhibitor, potentiates the resveratrol‐induced apoptosis of

Modulation of inflammation and pathology during dengue virus infection by p38 MAPK inhibitor SB203580

Antiviral Research, 2014
Dengue virus (DENV) infection could lead to dengue fever (DF), dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). The disease outcome is controlled by both viral and host factors. Inflammation mediators from DENV-infected cells could contribute to increased vascular permeability, leading to severe DHF/DSS.

SB203580 enhances the RV-induced loss of mitochondrial membrane potential and apoptosis in A549 cells

SPIE Proceedings, 2012
Resveratrol (RV), a naturally occurring phytoalexin, is known to possess a wide spectrum of chemopreventive and chemotherapeutic effects in various stages of human tumors. p38, a member of the mitogen-activated protein kinase (MAPK) superfamily, is always activated by some extracellular stimulus to regulate many cellular signal transduction pathways,

Phosphorylation of Initiation Factor 4E Is Resistant to SB203580 in Cells Expressing a Drug-Resistant Mutant of Stress-Activated Protein Kinase 2a/p38

Cellular Signalling, 2003
Previous work has shown that increased phosphorylation of eukaryotic initiation factor (eIF) 4E at Ser209 in the C-terminal loop of the protein is observed in response to cellular stress.

The p38 MAPK inhibitor SB203580 abrogates TNF-mediated expansion of regulatory T cells

The Journal of Immunology, 2017
Abstract CD4+FoxP3+ regulatory T cells (Tregs) represent a major cellular mechanism of immune evasion of tumor. There is compelling evidence that TNF is able to activate and expand Tregs through TNFR2. However, it remains unclear which TNFR2 signaling pathway(s) is required for the activation of Tregs.

The p38 MAPK Inhibitor, SB203580, Abrogates Ischaemic Preconditioning in Rat Heart but Timing of Administration Is Critical

Basic Research in Cardiology, 2000
There is debate concerning the involvement of p38 mitogen activated protein kinase (MAPK) in the mediation of ischaemic preconditioning. Pharmacological inhibition of p38 MAPK with SB203580 has been reported to block preconditioning in some studies but not in others.

The p38 MAPK Inhibitor SB203580 Blocks Adenosine A1 Receptor-Induced Attenuation of In Vivo Myocardial Stunning

Cardiovascular Drugs and Therapy, 2004
There is considerable evidence implicating a key role for p38 mitogen-activated protein kinase (MAPK) in ischemic and pharmacological preconditioning against myocardial infarction. However, there have been few, if any, studies examining the role of p38 MAPK in the protection of stunned myocardium.
