Description:
SB203580 is a highly selective and cell permeable inhibitor of p38 mitogen-activated protein kinase with IC50 values of 50 and 500 nM for p38/SAPK2a and p38/SAPK2b respectively. Also inhibits the phosphoinositide-dependent protein kinase 1 (PDK1) at 10-fold higher concentrations (IC50 ~3-5 µM). Displays 100-500-fold selectivity over Lck, GSK3b and Akt/PKB. Shown to inhibit interleukin-2-induced T-cell proliferation, cyclooxygenase-1 and -2 and thromboxane synthase.
