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
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 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]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
