Biological Activity for SB 203580

SB 203580 is a selective inhibitor of p38 MAPK (IC50 values are 50 and 500 nM for SAPK2a/p38 and SAPK2b/p38β2 respectively). Displays 100-500-fold selectivity over LCK, GSK-3β and PKBα. Shown to inhibit IL-2-induced T cell proliferation, cyclooxygenase-1 and -2, and thromboxane synthase. Enhances clonal growth of skin epithelial progenitor cells; stimulates neural stem cell (NSC) proliferation. SB 203580 is an essential component of medium for maintaining stem cells in naive pluripotent state and can be used to promote expansion of HSCs ex vivo.

Water-soluble Salt also available.

We ordered this product, combining with another inhibitor, to confirm the migration.To confirm that tested product induces migration, we also screen all MAPK inhibitors and MIF receptor antagonists

The role of p38 MAPK signaling in LPA induced pro-inflammatory phenotype in microglia cells.
By Joanna Plastira on 06/08/2019
Assay Type: In Vitro
Species: Mouse
Cell Line/Tissue: Primary murine microglia cells

The role of MAPK pathways (JNK, p38 and ERK) was studied in the LPA induced pro-inflammatory phenotype in microglia. In this case cells were incubated for the indicated time points with LPA (1µM) in the presence or absence of SB239063 (10µM) or SB203580 (10µM). A series of assays were performed. p38 MAPK inhibition totally decreased the expression of 4 pro-inflammatory transcription factors (here presented: pp65). Both inhibitors worked nicely and the results were consistent.

MAPK Signaling Scientific Review

MAPK Signaling Scientific Review

MAP kinase signaling is integral to the regulation of numerous cellular processes such as proliferation and differentiation, and as a result is an important focus of cancer and immunology research. Updated for 2016, this review discusses the regulation of the MAPK pathway and properties of MAPK cascades. Compounds available from Tocris are listed.

MAPK Signaling Pathway

MAPK Signaling Pathway

The mitogen-activated protein kinase pathway evokes an intracellular signaling cascade in response to extracellular stimuli such as heat and stress. It can influence cell division, metabolism and survival.
