A potent, cell-permeable, selective, and reversible inhibitor of c-Jun N-terminal kinase (JNK) (IC50=40nM 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-y, TNF-a, and COX-2 in cells. Blocks IL-1-induced accumulation of phospho-Jun and induction of c-Jun transcription.
Solubility:
DMSO (15mg/ml). For every 10uM concentration of JNK Inhibitor II, include 0.1% DMSO in the culture medium. Pre-warming of culture medium and addition of BSA to the medium may enhance its solubility.
Molecular Weight:
~220.2
Storage and Stability:
May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
