Biological Activity

SP600125 is a selective, ATP-competitive JNK inhibitor. SP600125 reversibly inhibits JNK1, 2 and 3 (IC50 = 40 - 90 nM) with negligible activity at ERK2, p38β and a range of enzymes (IC50 > 10 μM). SP600125 potently decreased renal epithelial tubular cell apoptosis induced by renal ischemia/reperfusion via suppression of the extrinsic pathway. In cells, SP600125 dose dependently inhibited the phosphorylation of c-Jun, the expression of inflammatory genes COX-2, IL-2, IFN-gamma, TNF-alpha, and prevented the activation and differentiation of primary human CD4 cell cultures. In mice, SP600125 (15 mg/kg or 30 mg/kg) blocked lipopolysaccharide (LPS)-induced TNF-α expression and anti-CD3-induced apoptosis of CD4(+) CD8(+) thymocytes.

Cell Experiment
Cell lines A549 cells
Preparation method Cell viability assay.
Cell viability was evaluated using the Cell Counting kit (CCK)-8 assay (AbMole). In brief, the cells were seeded into 96-well plates at a density of 3×103 cells/well and left to adhere overnight. The cells were then incubated with or without 0–40 nM SP600125. Then, 100 μl CCK-8 was added and incubated in the dark at 37°C for 3 h. The absorbance was determined using the MRX II microplate reader (Dynex, Chantilly, VA, USA) at a wavelength of 450 nm.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
