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 vitro assay. A cell permeable ethyl ester analog is also available (Catalog No. 14070).


Pale yellow powder. May be dissolved in DMSO (20 mg/ml, warm).

Storage Conditions

Store desiccated as supplied at room temperature for up to 2 years. Store solutions at -20°C for up to 3 months.
