GSK-J1 is a potent and selective
inhibitor of jumonji H3K27 histone demethylases JMJD3 and UTX (IC50
= 60 nM, human JMJD3). This is the first known inhibitor selective for the
H3K27me3-specific JMJ subfamily which binds to the active catalytic site of the
enzyme. The COOH group confers cell impermeability and as such is useful as a
standard in in vitro assays. A cell
permeable ethyl ester analog (GSK-J4) is also available.
