GSK J4 (GSK-J4) is a novel, cell permeable, and potent prodrug of GSK J1 with anti-inflammatory effects. It is the first selective and dual inhibitor of H3K27 histone demethylase (KDM) JMJD3 and UTX with IC50 of 60 nM in a cell-free assay and is inactive against a panel of demethylases of the JMJ family. GSK-J4 is used to probe the consequences of demethylation of H3K27me3. GSK-J4 inhibits the lipopolysaccharide-induced production of cytokines, including pro-inflammatory tumour necrosis factor (TNF). GSK-J4 (0.5 mg/kg, i.p.) significantly reduces the severity and delays the onset of the disease of the mouse model of experimental autoimmune encephalomyelitis.
ln Vitro |
In Flag-JMJD3-transfected HeLa cells, GSK-J4 hydrochloride exhibits cellular activity by averting JMJD3-induced decrease of nuclear H3K27me3 immunostaining. In untransfected cells, GSK-J4 administration raised the levels of total nuclear H3K27me3. Tumor necrosis factor-α (TNF-α) is one of the 16 LPS-driven cytokines that GSK-J4 dramatically lowers the expression of [1]. In mouse podocytes, GSK-J4 hydrochloride increased the amount of H3K27me3 by more than three times. In cultured podocytes, GSK-J4 lowers the levels of Jagged-1 protein and mRNA while raising H3K27me3. Similarly, pretreatment with GSK-J4 inhibited the increase in intracellular N1-ICD levels, the increase in α-SMA, and the decrease in podocyte protein mRNA levels when podocytes were subjected to the dedifferentiation inducer TGF-β1 [2]. Hydrochloride GSK-J4 While having little effect on Th1 and Th17 cell differentiation, hydrochloride (10, 25 nM) operates on DC to enhance Treg cell differentiation, stability, and inhibitory capacity [3]. Hydrochloride GSK-J4 TGF-β1-induced JMJD3 expression is inhibited by hydrochloride [4]. Hydrochloride GSK-J4 In female embryonic stem cells, hydrochloride suppresses the H3K4 demethylation of Xist, Nodal, and HoxC13 [5].

ln Vivo |
Hydrochloride GSK-J4 In diabetic mice, hydrochloride (10 mg/kg; intraperitoneal injection; three times a week for 10 weeks) is administered to prevent renal damage [2]. Hydrochloride GSK-J4 In a mouse model, hydrochloride (0.5 mg/kg, ip) considerably lessens the severity and postpones the development of experimental autoimmune encephalomyelitis [3].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
