Description

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-γ. In lung epithelial cells, SB-203580 inhibits TGF-β1-induced epithelial-to-mesenchymal transition (EMT). Additionally, SB-203580 inhibits proliferation in glioma cells and decreases angiotensin II- and TGF-β1-induced expression of GTGF and fibronectin in other cellular models.
