JNK

PT109 is a multikinase inhibitor that targets JNK and other kinases, playing a crucial role in anti-inflammatory, antioxidative, neurogenic, and synaptogenic processes. Specifically, PT109 inhibits JNK isoforms with the following IC50 values: JNK1 at 0.143 μM, JNK2 at 0.831 μM, and JNK3 at 0.285 μM. It also inhibits SGK isoforms (SGK1: IC50=1.34 μM; SGK2: IC50=5.6 μM; SGK3: IC50=26.4 μM) and ROCK2 (IC50=34 μM). Additionally, PT109 reprograms polymorphic glioblastoma multiforme (GBM) into oligodendroglia via the PTBP1/PKM1/2 pathway and alters the metabolic pattern of GBM to exhibit antiglioma activity.

JD123 inhibits the activity of JNK1 and the expression of cJun (1-135). It is an ATP-competitive inhibitor specific to p38-γ MAPK and has no effect on ERK1, ERK2, p38-α, p38-β, and p38-δ.

JAK3-IN-13: Oral JAK3 inhibitor, selective & potent. Acts on NK1, JNK2, JNK3, Tyk2. Anti-tumor. IC50: JNK3, 8 nM; Tyk2, 365 nM; JNK2, 2039 nM; NK1, 4728 nM.

TLR4/JNK/NF-κB-IN-1 (Racemic-11k) is an inhibitor of TLR4, JNK, and NF-κB. It suppresses NO production in LPS-stimulated RAW264.7 cells with an IC50 of 23.2 µM. By inhibiting TLR4 expression and reducing JNK phosphorylation, TLR4/JNK/NF-κB-IN-1 prevents NF-κB activation. This leads to a decrease in the transcription of inflammation-related genes, reducing the expression of iNOS and COX-2, and the production of inflammatory mediators such as NO, PGE2, and TNF-α, thereby exhibiting anti-inflammatory activity. TLR4/JNK/NF-κB-IN-1 holds potential in the study of inflammatory diseases, including rheumatoid arthritis and various other inflammatory conditions.

JNK-1-IN-5 (Compound 14) is a potent JNK1 inhibitor with sub-nanomolar efficacy. It effectively inhibits TGF-β-induced epithelial-mesenchymal transition and shows promise for research targeting JNK1 as an anti-pulmonary fibrosis agent.
