体外研究

SB 239063 potently inhibits IL-1 and TNF-α production in LPS-stimulated human peripheral blood monocytes with IC50 of 120 and 350nM, respectively. In oxygen-glucose-deprived hippocampal slice cultures, SB239063 strikingly reduces the levels of the pro-inflammatory cytokine IL-1beta, causes cell death after oxygen-glucose deprivation and significantly diminishes microglia activation. In human corneal endothelial cell, SB 239063 inhibits TGF-β(2) and FGF-2-induced cell migration.

体内研究

In both guinea pigs and mice, SB 239063 (10mg/kg, p.o.) reduces antigen-induced airway eosinophilia. In air- and ozone-exposed C57/BL6 and MKP-1(-/-) mice, SB239063 inhibits bronchial contraction.

方法

Yeast-expressed, activated, and purified p38α (3.55nM) is added to the reaction mixture (30μl) containing 25mM HEPES, pH 7.5; 10mM MgCl2; 0.2mM sodium orthovanadate; 1mM dithiothreitol; 0.1% BSA; 10% (w/v) glycerol; 0.17mM/2.5 μCi of [γ-32P]ATP; 0.67mM the endothelial growth factor receptor-derived T669 peptide as the substrate in the presence or absence of SB 239063. Incubation is for 25 min at 37℃ in 96-well plates, the reactions are stopped by adding 10μl of 0.3M phosphoric acid, and phosphorylated peptide is isolated from the reaction mixture on phosphocellulose (p81) filters. Filters are washed three times with 75mM phosphoric acid, followed by three times with H2O, and counted for bound 32P. The inhibitor is preincubated with the reaction mixture on ice for 30 min before starting the reactions with [γ-32P]ATP.
