3、lutionBIOLOGICAL ACTIVITY物活性 JNK-IN-8種有效的 JNK 抑制劑，抑制 JNK1，JNK2 和 JNK3，IC50 分別為 4.7 nM，18.7 nM 和 1 nM。IC50 & Target JNK3 JNK1 JNK21 nM (IC50) 4.7 nM (IC50) 18.7 nM (IC50)體外研究 JNK-IN-8 inhibits phosphorylation of c-Jun, a direct substrate of JNK kinase. JNK-IN-8 inhibits c-Junphosphorylation in HeLa a

4、nd A375 cells with EC50 of 486 nM and 338 nM, respectively. JNK-IN-8 alsoexhibits exceptional selectivity based upon KinomeScan and enzymatic profiling. Cumulatively thesecombined profiling technologies demonstrate that both JNK-IN-8 and JNK-IN-12 are remarkably selectivecovalent JNK inhibitors and

5、are appropriate for interrogating JNK-dependent biological phenomena 1. JNK-IN-8, a selective pan-JNK inhibitor, is discovered to inhibit JNK kinase by broad-base kinase selectivityprofiling of a library of acrylamide kinase inhibitors based on the structure of imatinib using the KinomeScaapproach.

6、JNK-IN-8 possess distinct regio-chemistry of the 1,4-dianiline and 1,3-aminobenzoic acidsubstructures relative to imatinib and uses an N,N-dimethyl butenoic actemide warhead to covalently targetCys154. JNK-IN-8 adopts an L-shaped type I binding conformation to access Cys 154 located towards the lipo

7、f the ATP-binding site 2.PROTOCOLKinase Assay 1 A375 cells are pre-treated with 1 M JNK-IN-8 for the indicated amounts of time. Remove the medium andwash 3 times with PBS. Resuspend the cell pellet with 1 mL Lysis Buffer (1% NP-40, 1% CHAPS, 25 mMTris, 150 mM NaCl, Phosphatase Inhibitor Cocktail, an

8、d Protease Inhibitor Cocktail). Rotate end-to-end for30 min at 4C. Lysates are cleared by centrifugation at 14000 rpm for 15 min in the Eppendorf. The clearedlysates gel filtered into Kinase Buffer (0.1% NP-40, 20 mM HEPES, 150 mM NaCl, Phosphatase InhibitorCocktail, Protease Inhibitor Cocktail) usi

9、ng Bio-Rad 10DG colums. The total protein concentration of the gel-filtered lysate should be around 5-15 mg/mL. Cell lysate is labeled with the probe from ActivX at 5 M for 1hour. Samples are reduced with DTT, and cysteines are blocked with iodoacetamide and gel filtered toremove excess reagents and

10、 exchange the buffer. Add 1 volume of 2X Binding Buffer (2% Triton-100, 1%NP-40, 2 mM EDTA, 2X PBS) and 50 L streptavidin bead slurry and rotate end-to-end for 2 hours,centrifuge at 7000 rpm for 2 min. Wash 3 times with 1X Binding Buffer and 3 times with PBS. Add 30 L 1Xsample buffer to beads, heat

11、samples at 95C for 10 min. Run samples on an SDSgel at 110V. Aftertransferred, the membrane is immunoblotted with JNK antibody 1.MCE has not independently confirmed the accuracy of these methods.
