  • DIPG cells were seeded into 96-well plates and treated with panobinostat and GSK-J4 individually or in combination at the indicated concentrations for 72 hr in at least triplicate. Cell viabilities were then assessed using the CelltiterGlo assay relative to 0.1% DMSO control. Data shown as mean ± SD. *indicates the two drugs demonstrate synergy at that condition (i.e. CI < 1).

    GSK-J4 impaired hair cell regeneration after neomycin damage. (A–D) GSK-J4 reduced the numbers of GFP-positive (green) and FM1-43FX-positive (red) hair cells compared with DMSO-treated controls. Scale bars = 10 μm. (E,F) Quantitative analysis of the number of GFP-positive (E) or FM1-43FX-positive (F) hair cells per neuromast (NM) at different time points in DMSO-treated control and GSK-J4-treated larvae. In the 24-h group, n = 40 neuromasts (20 larvae) per group; in the 48-h group, n = 28 neuromasts (14 larvae) per group. ***p < 0.0001. Bars are mean ± sem. [24-h group: One-way ANOVA; GFP-positive cells: F(2, 117) = 96.94; FM1-43FX-positive cells: F(2, 117) = 114. 48-h group: One-way ANOVA; GFP-positive cells: F(2, 81) = 88.96; FM1-43FX-positive cells: F(2, 81) = 93.85].

Biological Activity

Description GSK J4 HCl is a cell permeable prodrug of GSK J1, which is the first selective inhibitor of the H3K27 histone demethylase JMJD3 and UTX with IC50 of 60 nM in a cell-free assay and inactive against a panel of demethylases of the JMJ family.
JMJD3 [1]
(Cell-free assay)
60 nM
In vitro

GSK J4 HCl is an ethyl ester derivative of the JMJD3 selective histone demethylase inhibitor GSK-J1 with an IC50 value greater than 50 μM in vitro. GSK J4 HCl is used to probe the consequences of demethylation of H3K27me3. In human primary macrophages, GSK-J4 inhibits the lipopolysaccharide-induced production of cytokines, including pro-inflammatory tumour necrosis factor (TNF). In addition, GSK-J4 prevents the lipopolysaccharide-induced loss of H3K27me3 associated with the TNF transcription start sites and blocked the recruitment of RNA polymerase II. [1]
