| Description | SP-600125 (129-56-6) is a selective inhibitor of c-Jun N-terminal kinase (JNK). Reversibly inhibits JNK1,2 and 3 (IC50‘s range from 40-90 nM). >300-fold selectivity for JNK as compared to related MAP kinases. Anti-inflammatory activity. SP-600125 inhibits expression of presenilin-1 and Notch signaling in mouse brain. Cell permeable and active in vivo. | | Uses | SP 600125 is a Jun N-terminal kinase (JNK) inhibitor. | | Uses | A broad-spectrum serine/threonine kinase inhibitor of JNK with an IC50 range from 40 to 90 nM. | | Uses | C2C12 myoblasts were treated with SP600125 to test the stimulation of myogenesis.11 It was used to treat HepG2 cells to test the effects on oxysterol-induced necrosis.12 | | Definition | ChEBI: A member of the class of anthrapyrazoles that is anthra[1,9-cd]pyrazole substituted at position 6 by an oxo group. An inhibitor of c-Jun N-terminal kinase. | | General Description | A potent, cell-permeable, selective, and reversible inhibitor of c-Jun N-terminal kinase (JNK) (IC50 = 40 nM for JNK-1 and JNK-2 and 90 nM for JNK-3). The inhibition is competitive with respect to ATP. Exhibits over 300-fold greater selectivity for JNK as compared to ERK1 and p38-2 MAP kinases. Inhibits the phosphorylation of c-Jun and blocks the expression of IL-2, IFN-γ, TNF-α, and COX-2 in cells. Blocks IL-1-induced accumulation of phospho-Jun and induction of c-Jun transcription. | | Biological Activity | Selective inhibitor of c-Jun N-terminal kinase (JNK). Competitively and reversibly inhibits JNK1, 2 and 3 (IC 50 = 40-90 nM) with negligible activity at ERK2, p38 β and a range of enzymes (IC 50 > 10 μ M). Active in vivo . Shown to have reduced selectivity over other protein kinases under certain conditions. Protects renal tubular epithelial cells against ischemia/reperfusion-induced apoptosis. Also available as part of the MAPK Inhibitor Tocriset™ . | | Biochem/physiol Actions | SP600125 is an anthrapyrazolone inhibitor of JNK that competes with ATP to inhibit the phosphorylation of c-Jun. It prevents the activation of inflammatory genes such as COX-2, IL-2 IFN-γ and TNF-α.8,9 It prevents the activation of JNK after brain ischemia and may be effective in treatment of ischemic stroke.10 | | Safety Profile | Poison by intravenous route.When heated to decomposition it emits toxic fumes ofNOx. | | Synthesis | 1,9-Pyrazolanthrone is prepared by diazotization
of 1-aminoanthraquinone, reaction of the
diazonium salt with sodium hydrogen sulfite,
and cyclization of the resulting hydrazinosulfonic
acid . | | storage | -20°C (desiccate) | | References | 1)Bennett et al. (2001), SP600125, an anthrapyrazolone inhibitor of Jun N-terminal kinase; Proc. Natl. Acad. Sci. USA., 98 13681
