Background

GSK J4 is a potent cell-permeable inhibitor of the histone H3 lysine 27 (H3K27) demethylase JMJD3, an essential component of regulatory transcriptional chromatin complexes, with the half maximal inhibition concentration IC50 value > 50 μM in vitro [1].

GSK J4 is an ethyl ester derivative of GSK J1, which is a potent JMJD3 inhibitor (IC50: 60 nM) with restricted cellular permeability due to the highly polar carboxylate group, and rapidly hydrolyzed by macrophage esterase upon administration leading to the generation of pharmacologically relevant intracellular concentration of GSK-J1 [1].

GSK J4 has also been found to dose-dependently inhibit the production of tumor-necrosis factor-α (TNF-α), a LPS-driven cytokine involved in various fnflammatory disorders, with IC50 value of 9μM [1].

General tipsFor obtaining a higher solubility, please warm the tube at 37°C and shake it in the ultrasonic bath for a while. Stock solution can be stored below -20°C for several months.

Protocol

Cell experiment [1]:

Cell lines

Human primary macrophages

Preparation method

The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20 °C for several months.

Reaction Conditions

1, 3, 10 and 31 μM; 6 hrs

Applications

GSK J4 inhibited TNF-α protein production in a dose-dependent manner, with an IC50 value of 9 μM.

Animal experiment [2]:

Animal models

Mice harboring subcutaneous SF8628 K27M xenografts

Dosage form

100 mg/kg/day; i.p.; for 10 days

Applications

GSK J4 showed significant growth-inhibitory activity against SF8628 subcutaneous tumors.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
