Cell permeable, specific p38 MAP kinase inhibitor, Binds to the ATP binding site of p38 MAP kinase, T cell proliferation inhibitor, IL-2 production inhibitor, SAPK/JNK inhibitor, COX-1 and -2 inhibitor, Raf-1 activator, Apoptosis enhancer, Antiproliferative, PDK1 inhibitor, Anti-inflammatory, Review.

Mitogen-activated protein kinases (MAPK) mediate signal transduction from cell surface receptors to the nucleus and are classified into various subtypes. p38 MAPK is activated by environmental stresses and inflammatory cytokines and is critical for normal immune and inflammatory responses as it regulates the...

SB-203580 is an inhibitor of p38 MAPK that exhibits immunostimulatory, anticancer, and anti-fibrotic activities. In peripheral blood mononuclear cells, SB-203580 increases secretion of IFN- . In lung epithelial cells, SB-203580 inhibits TGB- 1-induced epithelial-to-mesenchymal transition (EMT). Additionally,...

Soluble in DMSO at 100 mg/mL, soluble in ethanol at 12.5 mg/mL with warming, very poorly soluble in water, maximum solubility in plain water is estimated to be about 10-50 µM, buffers, serum, or other additives may increase or decrease the aqueous solubility

Important, highly specific inhibitor of the kinase known variously as p38, p40, CSBP, or RK. This kinase is a homolog of MAP kinase. Gallagher, T.F., et al.
