Biological Activity for SB 203580 hydrochloride

SB 203580 hydrochloride is a water-soluble salt of SB 203580 (Cat. No. 1202). Selective inhibitor of p38 mitogen-activated protein kinase (IC₅₀ values are 50 and 500 nM for SAPK2a/p38 and SAPK2b/p38β2 respectively). Displays 100-500-fold selectivity over LCK, GSK3β and PKBα. Shown to inhibit interleukin-2-induced T cell proliferation, cyclooxygenase-1 and -2, and thromboxane synthase.
