Verwenden
MDCK cells were treated with SB 203580 to study the role of MAPK signaling in inducing hypertonicity of cell membrane and potassium depletion.
16 It was used to inhibit MAPK signaling in mouse cortical neurons
17 and human hepatocellular carcinoma cell lines.

Definition
ChEBI: A member of the class of imidazoles carrying 4-methylsulfinylphenyl, 4-pyridyl and 4-fluorophenyl substituents at positions 2, 4 and 5 respectively. An inhibitor of mitogen-activated protein kinase.
Allgemeine Beschreibung
Reduces epirubicin-induced cell injury and caspase-3/7 activity. A highly specific, potent, cell-permeable, selective, reversible, and ATP-competitive inhibitor of p38 kinase (IC
50 = 34 nM in vitro, 600 nM in cells). Also known as reactivating kinase (RK) and CSBP (cytokine synthesis anti-inflammatory drug binding protein). Does not significantly inhibit JNK or p42 MAP kinase even at 100 μM. Inhibits IL-1 and TNF-α production from LPS-stimulated human monocytes and the human monocyte cell line THP-1 (IC
50 = 50-100 nM). SB 203580 has also been shown to be an effective inhibitor of inflammatory cytokine production in vivo in both mice and rats.
Biologische Aktivit?t
Water-soluble salt of SB 203580 (4-[5-(4-Fluorophenyl)-2-[4-(methylsulfonyl)phenyl]-1H-imidazol-4-yl]pyridine ). Selective inhibitor of p38 mitogen-activated protein kinase (IC 50 values are 50 and 500 nM for SAPK2a/p38 and SAPK2b/p38 β 2 respectively). Displays 100-500-fold selectivity over LCK, GSK3 β and PKB α . Shown to inhibit interleukin-2-induced T-cell proliferation, cyclooxygenase-1 and -2, and thromboxane synthase.
