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]
