SB 203580 hydrochloride
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.

We investigate the effect of LPA on microglia metabolic states. Trying to unravel possible pathways that maybe involved in this process, we used LPAR inhibitors and downstream inhibitors of MAPKs pathway. SB 203580 was used at a concentration of 10µM yet couldn't inhibit the expression of pAMPK. However the inhibitor was well tolerated by the cells.
MG-63 cells were pre-incubated with 10 µM SB 203580 for 30 min followed by treatment with 10 µM LPA for 3 h to follow COX-2 expression using Western blot. SB 203580 inhibited COX-2 induction by LPA.
HL-1 cells were incubated with p38 MAPK inhibitor (10 µM SB203580, 25 µMPD169316) or p42/44 MAPK kinase inhibitor (25 µM PD98059) for 30 min prior to 15dPGJ2 treatment (15 µM, 1 h). Immunoreactive bands for pp38 and pp42/44 MAPK expressions were followed by Western blot. SB203580 completely inhibited 15d-PGJ2 induced p38 phosphorylation (shown in Image).

MAPK Signaling Scientific Review
MAP kinase signaling is integral to the regulation of numerous cellular processes such as proliferation and differentiation, and as a result is an important focus of cancer and immunology research. Updated for 2016, this review discusses the regulation of the MAPK pathway and properties of MAPK cascades. Compounds available from Tocris are listed.
