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 cellular expression of IL-2, IFN-γ, TNF-α, and COX-2. Blocks IL-1-induced accumulation of phospho-Jun and induction of c-Jun transcription. A 50 mM (5 mg/454 µl) solution of JNK Inhibitor II (Cat. No. 420128) in DMSO is also available.
