jnk-3 inhibitor-1

JNK3 inhibitor-1 is a highly potent and selective compound that specifically inhibits JNK3 with an impressive IC50 value of 0.005 μM. In addition to its remarkable inhibitory effects, JNK3 inhibitor-1 possesses excellent oral bioavailability and the ability to efficiently penetrate the brain.

1. 2,5-Dihydroxyacetophenone (Quinacetophenone) possess anti-anxiety, and neuroprotective qualities. 2. 2,5-Dihydroxyacetophenone (Quinacetophenone) reatment can induce a sustained activation of JNK, ERK1 2, and p38 MAPKs, it also can potentiate the pro-apoptotic and anti-proliferative effects of bortezomib in U266 cells. 3. 2,5-Dihydroxyacetophenone (Quinacetophenone) has anti-inflammatory activity in activated macrophages, raising the possibility that this compound has a therapeutic potential for inflammatory conditions. 4. 2,5-Dihydroxyacetophenone (Quinacetophenone) is an uncompetitive inhibitor of murine tyrosinase (K(I) 0.28mm), it strongly inhibits both melanogenesis and cellular tyrosinase activity in vitro in 3-isobutyl-1-methylxanthin-stimulated B16 mouse melanoma cells or in vivo in zebrafish and mouse models.

TCS JNK 5a (SC202671) is an effective, specific inhibitor of JNK3(pIC50= 6.7), JNK2(pIC50=6.5).

JNK-1-IN-3 (Compound 9e) acts as a JNK1 inhibitor, both reducing JNK1 gene expression and lowering the protein levels of its phosphorylated form. It concurrently diminishes the expression of downstream targets c-Jun and c-Fos in tumors, while also restoring p53 activity. Exhibiting broad-spectrum antiproliferative effects, JNK-1-IN-3 is particularly effective against renal and breast cancer cell lines, showing significant anticancer activity both in vivo and in vitro.

JNK-1-IN-4 (Compound E1) is an inhibitor of JNK, targeting JNK-1, JNK-2, and JNK-3 with IC50 values of 2.7, 19.0, and 9.0 nM, respectively. This compound inhibits the phosphorylation of c-Jun and reduces the expression of TGF-β1-induced EMT markers (such as fibronectin and α-SMA). JNK-1-IN-4 exhibits favorable pharmacokinetic properties with a bioavailability of 69%. Additionally, it demonstrates antifibrotic effects in a Bleomycin-induced mouse model of idiopathic pulmonary fibrosis.

JNK Inhibitor VIII (TCS JNK 6o) is an ATP-competitive, selective inhibitor of c-Jun N-terminal kinase (JNK) with IC50 values of 45 nM for JNK-1 and 160 nM for JNK-2.

JNK-1-IN-2 (Compound c6) is a potent inhibitor of JNK-1 with an IC50 of 33.5 nM, and also exhibits inhibitory effects on JNK-2 and JNK-3 with IC50 values of 112.9 nM and 33.2 nM, respectively. This compound effectively inhibits the phosphorylation of c-Jun and has shown potential in reversing lung impairment, making it relevant for research into pulmonary fibrosis [1].

JNK-IN-14 is a potent inhibitor of JNK with IC50 values of 1.81 nM for JNK1, 12.7 nM for JNK2, and 10.5 nM for JNK3. It induces early-stage apoptosis, arrests cell population at the G2 M phase, and moderately inhibits beclin-1 production in K562 leukemia cells, demonstrating greater inhibitory efficacy than SP600125.
