Description: JNK-IN-8, also known as JNK Inhibitor XVI, is a selective JNK inhibitor that inhibits phosphorylation of c-Jun, a direct substrate of JNK, in cells exposed to submicromolar drug in a manner that depends on covalent modification of the conserved cysteine residue. Extensive biochemical, cellular, and pathway-based profiling establish the selectivity of JNK-IN-8 for JNK and suggests that the compound will be broadly useful as a pharmacological probe of JNK-dependent signal transduction.

| Biological target: | JNK-IN-8 (JNK Inhibitor XVI) is the first irreversible JNK inhibitor for JNK1, JNK2 and JNK3 with IC50 of 4.7 nM, 18.7 nM and 1 nM, >10-fold selectivity against MNK2, Fms and no inhibition to c-Kit, Met, PDGFRβin A375 cell line. |
| In vitro activity: | Before assessing the effects of JNK-IN-8 on primary murine peritoneal macrophages, the cytotoxic effect of JNK-IN-8 on cells was assessed using a CCK-8 assay (Fig. 4A). No significant cytotoxic effects of JNK-IN-8 were observed at concentrations of ≤12.50 µM in primary macrophages (Fig. 4A). Based on these data, a maximal concentration of 10 µM was selected to analyze the effects of JNK-IN-8 in primary macrophages. In order to investigate the anti-inflammatory effect of JNK-IN-8, primary macrophages were pretreated with JNK-IN-8 for 1 h and then stimulated with LPS (100 ng/ml) for 6 h. mRNA expression levels and secretion of TNF-α, IL-6 and IL-1β in the LPS group were significantly increased compared with those in the Sham group, but these were decreased in the LPS + JNK-IN-8 group compared with the LPS group (Fig. 4B and C). Subsequently, the role of JNK-IN-8 in oxidative stress was investigated. JNK-IN-8 pretreatment significantly decreased MDA content and inhibited the LPS-induced decrease in SOD activity (Fig. 4D) in primary macrophages. The effects of JNK-IN-8 on the macrophage cell line RAW264.7 were assessed. In the CCK-8 assay, no cytotoxic effects of JNK-IN-8 were observed at concentrations ≤12.50 µM in RAW264.7 cells (Fig. 5A). RAW264.7 cells were cultured and treated with JNK-IN-8 in vitro. The trend was the same as that of primary macrophages. RAW264.7 cells were pretreated with JNK-IN-8 for 1 h and then stimulated with LPS (100 ng/ml) for 6 h. The gene expression levels and secretion of TNF-α, IL-6 and IL-1β were decreased by JNK-IN-8 pretreatment compared with those in the LPS group (Fig. 5B and C). JNK-IN-8 administration significantly decreased the MDA content and inhibited the LPS-induced decrease in SOD activity (Fig. 5D).

| In vivo activity: | Male rats were treated with JNK-IN-8 after transient middle cerebral artery occlusion, and then the modified improved neurological function score (mNSS), the foot-fault test (FFT), interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α) levels were assessed. It was found that JNK-IN-8-treated rats with MCAO exerted an observable melioration in space learning as tested by the improved mNSS, and showed sensorimotor functional recovery as measured by the FFT. JNK-IN-8 also played anti-inflammatory roles as indicated through decreased activation of microglia and decreased IL-6, IL-1β, and TNF-α expression. Furthermore, JNK-IN-8 suppressed the activation of JNK and nuclear factor-κB (NF-κB) signaling as indicated by the decreased level of phosphorylated-JNK and p65. All data demonstrate that JNK-IN-8 inhibits neuroinflammation and improved neurological function by inhibiting JNK/NF-κB and is a promising agent for the prevention of ischemic brain injury.
