5%DMSO 40%PEG300 5%Tween80 50%ddH2O
3.9mg/ml Taking the 1 mL working solution as an example, add 50 μL of 78 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description GSK-J1 is a highly potent inhibitor of H3K27 histone demethylase JMJD3 (KDM6B) and UTX (KDM6A) with IC50 of 60 nM in cell-free assays for JMJD3 (KDM6B) , respectively, >10-fold selectivity over other tested demethylases, with IC50 of 0.95μM and 1.76μM towards JARID1B/C.
Targets
JMJD3 [1]
60 nM
In vitro

In HEK-293 cells, GSK-J1 inhibits the activities of transiently transfected JMJD3 and UTX. GSK-J1 also inhibits TNF-α production by human primary macrophages by increasing total nuclear H3K27me3 levels. [1]

In MC3T3-E1 cells, GSK-J1 suppresses Runx2 and Osterix expressions and ALP activity, and increases the global levels of H3K27me3. [2]
In vivo

GSK-J1, a small molecule inhibitor of JMJD3, directly interfered with the transcription of inflammatory-related genes by H3K27me3 modification of their promoters.

Protocol (from reference)

Kinase Assay:

[1]
  • MALDI-TOF Analysis of JmjD3 and UTX Activity

    Purified JmjD3 (1 μM) and UTX (3 μM) is incubated with 10 μM peptide [Biotin-KAPRKQLATKAARK(me3)SAPATGG] in 50 mM HEPES pH 7.5, 150 mM KCl, 50μM (NH4)2SO4·FeSO4·H2O, 1 mM 2-oxoglutarate, and 2 mM ascorbate (JmjD3, 3 minutes at 25°C; UTX, 20 minutes at 25°C) with various concentration of the inhibitor (0, 0.005, 0.01, 0.02, 0.05, 0.1 μM). 10mM EDTA is added to stop the reaction. The reaction is desalted by zip tip and spotted on a MALDI plate with α-cyano-4-hydroxycinnamic acid MALDI matrix. Samples are analysed on a MALDI-TOF R system.
