GSK-J1 is the first selective and potent inhibitor of the H3K27 histone demethylases UTX and JMJD3. H3K27 methylations play important roles in regulating gene expression through the polycomb-repressive complex (PRC1 or PRC2). This epigenetic mark can be demethylated by lysine demethylase (KDM) UTX and JMJD3, which play important roles in cellular differentiation, development and cancer. In relevant biological assays, GSK-J1 was shown to reduce lipopolysaccharide-induced pro-inflammatory cytokine production by human primary macrophages, a process that depends on both UTX and JMJD3. GSK-J1 represents a unique small molecule tool to allow selective pharmacological intervention across the JMJ family. Although critical for in vitro binding, the highly polar carboxylate group of GSK-J1 restricts its cellular permeability. Therefore another compound, GSK-J4, was developed as a pro-drug, masking the polarity of the acid group of the GSK-J1, for cellular assays.
