JAK2-IN-20
JAK2-IN-20 is an orally active dual inhibitor targeting JAK2 kinase (IC50=49.17 nM) and influenza A virus PB2 protein (IC50=3.337 μM, Kd=2.82 μM). JAK2-IN-20 effectively blocks the JAK/STAT signaling pathway by reducing the phosphorylation levels of STAT1 and STAT3, thereby inhibiting viral replication and downregulating the expression of viral NP and PB2 proteins. In addition, JAK2-IN-20 significantly inhibits the mRNA expression of key inflammatory cytokines such as IL-6, TNF-α and IFN-β in inflammation and influenza infection models. JAK2-IN-20 serves as an important tool molecule for the study of influenza A virus infection and related pathologies.

Biological Activity
|
JAK2 49.17 nM (IC50) |
JAK2-IN-20 (compound 4B) potently protects MDCK cells against damage induced by H1N1 influenza virus (EC50=14.71 nM) and inhibits the cap-binding activity of influenza A PB2 protein (IC50=3.337 nM)[1].
JAK2-IN-20 exhibits low cytotoxicity in multiple cell lines, with a CC50 of >100 μM (48 h) in MDCK cells[1].
JAK2-IN-20 (1 μM; 60 min; 37°C) exhibits excellent metabolic stability in mouse liver microsomes, with a half-life of 47.8 min and an intrinsic clearance (CLint) of 29.0 μL/min/mg[1].
JAK2-IN-20 (250-2000 nM) binds directly to the cap-binding domain of influenza A virus PB2, with a Kd value of 2.82 μM[1].
JAK2-IN-20 (5-10 μM; 30 min; 6 h) dose-dependently inhibits LPS (1 μg/mL)-induced expression of pro-inflammatory cytokines (IL-6, IL-1β) and IFN-β in RAW 264.7 macrophages, and exhibits potent activity at 10 μM[1].
JAK2-IN-20 (5-10 μM; 30 min; 6 h) potently inhibits the expression of poly (I:C)-induced proinflammatory cytokines (IL-6, TNF-α) and type I interferons (IFN-α, IFN-β) in RAW 264.7 macrophages at a concentration of 10 μM[1].
JAK2-IN-20 (250-500 nM; 24 h) inhibits the expression of H1N1 virus PB2 mRNA and reduces the levels of virus-induced proinflammatory cytokines (IL-6, TNF-α) in A549 cells at a concentration of 500 nM[1].
JAK2-IN-20 inhibits the JAK/STAT signaling pathway in both H1N1-infected A549 cells and IFN-β-stimulated THP-1 cells by reducing the phosphorylation levels of STAT1 and STAT3[1].
