Molecular Weight 368.4 CAS No. 193551-21-2
Solubility (25°C)* In vitro DMSO 60 mg/mL (162.86 mM)
Ethanol 7 mg/mL (19.0 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO Corn oil
3.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 60 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description SB239063 is a potent and selective p38 MAPKα/β inhibitor with IC50 of 44 nM, showing no activity against the γ- and δ-kinase isoforms.
Targets
p38α [1]
(Cell-free assay)		 p38β [1]
(Cell-free assay)
44 nM 44 nM
In vitro SB 239063 potently inhibits IL-1 and TNF-α production in LPS-stimulated human peripheral blood monocytes with IC50 of 120 and 350 nM, respectively. [1] 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. [2] In human corneal endothelial cell, SB 239063 inhibits TGF-β(2) and FGF-2-induced cell migration. [4]
In vivo In both guinea pigs and mice, SB 239063 (10 mg/kg, p.o.) reduces antigen-induced airway eosinophilia. [1] In air- and ozone-exposed C57/BL6 and MKP-1(-/-) mice, SB239063 inhibits bronchial contraction. [3]
