Biological Activity

Description JNK Inhibitor VIII (TCS JNK 6o) is an inhibitor of c-Jun N-terminal kinases with IC50 of 45 nM and 160 nM for JNK-1 and JNK-2, respectively. JNK Inhibitor VIII (TCS JNK 6o) inihibits JNK-1, JNK-2, and JNK-3 with Ki of 2 nM, 4 nM and 52 nM, respectively.

In vitro

TCS-JNK-6a binds competitively and reversibly to the ATP site. This compound demonstrates a remarkable selectivity profile. Additionally, it shows some inhibition of c-Jun phosphorylation in hepG2 cells. TCS-JNK-6o is a 2,5-dimethoxy analogue of TCS-JNK-6a with the dimethoxy substitution of the phenyl ring. TCS-JNK-6o shows further gains in potency.[1]
In vivo

Pharmacokinetic profiles are determined for JNK Inhibitor VIII (TCS-JNK-6o) in Sprague-Dawley rats. JNK Inhibitor VIII (TCS-JNK-6o) showes a short half-life of roughly 1 h, with rapid clearance and barely measurable bioavailability. Microsomal incubation studies revealed that oxidative metabolism is very rapid with this compound.[1]

Protocol (from reference)

Kinase Assay:

[1]
  • Ser/Thr-kinase

    Ser/Thr-kinase assays are performed using a radioactive FlashPlate-based assay platform. In this format, biotinylated substrate peptide (2 μM), γ-[33P]-ATP (5 μM, 2 mCi/μmol), inhibitors (3-10000 nM in 2% DMSO), and enzyme are incubated for 1 h in buffer containing 25 mM Hepes, pH 7.5, 1 mM DTT, 10 mM MgCl2, 100 μM Na3VO4, and 0.075 mg/mL Triton X-100, stopped with 80 μL of stop buffer containing 100 mM EDTA and 4 M NaCl, transferred to streptavidin-coated 384-well FlashPlates, which are then washed 3 times and read using a TopCount microplate reader.
Cell Assay:

  • Cell lines

    hepG2 cells

  • Concentrations

    Serial concentrations

  • Incubation Time

    1 h

  • Method

    HepG2 human hepatoma cells (ATCC) are cultured in low glucose MEM supplemented with 1×NEAA, 1×sodium pyruvate, and 10% FBS. For P-c-Jun assays, cells are plated at 5×104 cells/well in 500 μL of complete media on 24-well collagen-coated plates and incubated overnight. Serial compound dilutions are made in DMSO at 100×, and then 5 μL is added directly to the media on the cells to provide the final inhibitor concentrations. After 1 h, cells are stimulated with vehicle control or TNFR for 30 min and harvested in 70μL of lysis buffer (TBS (54 mM Tris-HCl, pH 7.6, 150 mM NaCl), 1% TritonX-100,0.5% Nonidet P-40, 0.25% sodium deoxycholate, 1 mM EDTA, 1 mM EGTA, 0.5 mM sodium fluoride, 1 mM pervanadate, 1 μM microcystin, 1 mM AEBSF, 1 tablet of complete EDTA Free-Mini inhibitor cocktail) and frozen at -80 °C prior to use in the P-c-Jun assay.
Animal Study:

  • Animal Models

    Sprague-Dawley rat

  • Dosages
