Protocol

Cell experiment: [1]

Cell lines

MIN6 cells

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months.

Reaction Conditions

40 μM, 36 hours

Applications

When the MIN6 cells were transfected with the Gal4 plasmid and CREB plasmid, SP600125 significantly stimulated CREB-mediated promoter activity in a dose-dependent manner. There was a 2.8-fold increase in this reporter activity after exposure of the transfected MIN6 cells to 20 μM of the inhibitor.

Animal experiment: [2]

Animal models

Female C57BL/6 mice

Dosage form

Subcutaneous injection; 15 mg/kg; administered at 0, 12, 24, and 36 h

Applications

Anti-CD3 (50 μg) i.p. was administered as a single dose immediately after SP600125 at time 0. After 48 h, mice were killed, and the thymus was dissected for thymocyte isolation. Mice receiving SP600125 showed almost complete resistance to CD3 Ab-mediated apoptosis with CD4+CD8+ numbers the same as control animals.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

SP600125 is a selective, reversible and ATP-competitive inhibitor of Jun N-terminal kinase (JNK) with IC50 values of 40, 40 and 90 nM for JNK1, 2 and 3, respectively [1].

SP600125 was screened out from a time-resolved f luorescence assay using the GST-c-Jun and recombinant human JNK2. In this assay, SP600125 showed a Ki value of 190 nM. SP600125 was also found to inhibit JNK1, 2 and 3 isoforms in the selectivity tests. The selectivity of SP600125 for JNK is 300-fold greater than that for ERK1 and p38-2. In Jurkat T cells, SP600125 suppressed the phosphorylation of c-Jun with IC50 of 5-10 μM. SP600125 also inhibited the expression of IL-2 and IFN-γ in cells stimulated with PMA and phytohemagglutinin, since JNK had been reported to regulate the transcription of IL-2. Besides that, SP600125 exerted differential inhibition of cytokines in CD4+ cells as well as inflammatory genes in monocytes. Moreover, SP600125 administration significantly inhibited TNF-α expression induced by LPS in a mouse model, suggesting that it had efficacy in endotoxin-induced inf lammation in vivo [1].
