    Description:  A highly specific, cell-permeable inhibitor of p38 kinase (IC50=34nM in vitro, 600nM in cells). Inhibition is competibive with ATP (Ki=21nM). Inhibites p38 MAPK stimulation of MAPKAPK2 (IC50=70nm). Also known as reactivating kinase (RK) and CSBP (cytokine synthesis anti-inflammatory drug binding protein). Does not significantly inhibit JNK or p42 MAP kinase even at 100μM Inhibits IL-1 and TNF-α production from LPS-stimulated human monocytes and the human monocyte cell line THP-1 (IC50=50-100nM). SB 203580 has also been shown to be an effective inhibitor of inflammatory cytokine production in vivo in both mice and rats.
