Potent and selective inhibitor of the protein lysine methyltransferase SETD8 (IC50 = 0.21 µM) which efficiently suppresses cellular H4K20me1 at doses lower than 5 µM (ref 1). Also inhibits CDC25 phosphatases (ref 2). Arrests cells at G1 and G2/M and inhibits cdk1 and 2 activation (ref 3). Inhibits the growth of a variety of human tumor cell lines (ref 4).


Red powder. May be dissolved in DMSO (15 mg/ml); or ethanol (55 mg/ml).
