GSK J4 hydrochloride

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. (In Vitro) :GSK-J4 has cellular activity in Flag-JMJD3-transfected HeLa cells, in which GSK-J4 prevents the JMJD3-induced loss of nuclear H3K27me3 immunostaining. Administration of GSK-J4 increases total nuclear H3K27me3 levels in untransfected cells. GSK-J4 significantly reduces the expression of 16 of 34 LPS-driven cytokines, including tumour-necrosis factor-α (TNF-α) .GSK-J4 (5 μM; 48 hours) causes a more than 3-fold increase in mouse podocyte H3K27me3 content. H3K27me3 levels in cultured podocytes, GSK-J4 reduces Jagged-1 mRNA and Jagged-1 protein levels. Correspondingly, when exposed podocytes to the inducer of dedifferentiation TGF-β1, pretreatment with GSK-J4 preventes both the increase in intracellular N1-ICD levels and the increase in α-SMA and the decrease in podocin mRNA levels.GSK-J4 (10, 25 nM) acts upon DCs promoting the differentiation of Treg cells, improving Treg stability and suppressive capacities, without affecting the differentiation of Th1 and Th17 cells.GSK-J4 inhibits JMJD3 expression that is induced by TGF-β1.GSK-J4 inhibits H3K4 demethylation at Xist, Nodal, and HoxC13 in female embryonic stem cells. (In Vivo) :GSK-J4 Hydrochloride (10 mg/kg; i.p.; thrice-weekly for 10 weeks) attenuates the development of kidney disease in diabetic mice.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.
