Anthra[1,9-cd]pyrazol-6(2H)-one 1,9-pyrazoloanthrone SAPK Inhibitor II SP600125 Yellowish orange solid. PROTECT FROM LIGHT. PACKAGED UNDER INERT GAS. 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 cellular expression of IL-2, IFN-g, TNF-a, and COX-2. Blocks IL-1-induced accumulation of phospho-Jun and induction of c-Jun transcription.
