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.

Biochem/physiol Actions

Cell permeable: yes
Primary Target
JNK 1, JNK 2, JNK 3
Product competes with ATP.
Reversible: yes
Target IC50: 40 nM for JNK-1 and JNK-2 and 90 nM for JNK-3

Packaging

Packaged under inert gas

Preparation Note

Following reconstitution, aliquot and freeze at -20°C. Stock solutions are stable for up to 2 months at -20°C.
For every 10 µM 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.

Human Kinome & InhibitorSelect™ Libraries

Human Kinome Poster: The InhibitorSelect™ Protein Kinase Inhibitor Libraries provide broad coverage of the human kinome as shown here. The depicted human kinome dendrogram of 518 kinases are classified into five broad groups, 90 families, and 145 subfamilies. Inhibitor coverage was assigned based upon published data related to potency (IC50, EC50, Kd, etc.) for individual kinases harvested from the literature. Colored dots denote which library contains an inhibitor with demonstrated potent activity against the designated kinase and do not necessarily reflect known specificity of the inhibitor. Coverage of lipid and atypical kinases are depicted as a separate dendrogram. As shown, Calbiochem® Protein Kinase Inhibitor Libraries cover all major kinase families including TK, CMGC, CAMK, AGC, CK1, STE, TKL, as well as Lipid or Atypical kinase families.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
