Description

SB203850 is a p38 MAPK inhibitor. SB203580 inhibits the phosphorylation of heat shock protein (HSP) 27 in response to IL-1, cellular stresses and bacterial endotoxin in vivo. SB203850 is useful for studying the physiological roles and targets of p38 MAPK and MAPKAP kinase-2.

How to use

In Vitro:

SB203580 inhibits the IL-2-induced proliferation of primary human T cells, murine CT6 T cells, or BAF F7 B cells with an IC50 of 3–5 μm. SB203580 also inhibits IL-2-induced p70S6 kinase activation, although the concentration required is slightly higher with an IC50 above 10 μm. SB203580 also inhibits the activity of PDK1 in a dose-dependent manner with an IC50 in the 3–10 μm range. SB203580 inhibits p38-MAPK stimulation of MAPKAPK2 with an IC50 of approximately 0.07 μM, whereas inhibits total SAPK/JNK activity with an IC50 of 3–10 μM. SB203580 at higher concentrations activates the ERK pathway, which subsequently enhances NF-κB transcriptional activity. SB203580 induces autophagy in human hepatocellular carcinoma (HCC) cells.

In Vivo:

SB203580 protects pig myocardium against ischemic injury in an in vivo model. SB203580 is effective to prevent and treat the disease in MRL/lpr mice model of Systemic lupus erythematosus (SLE).
