Discovery of Bisubstrate Inhibitors for Protein N-Terminal Methyltransferase 1

Journal Article · · Journal of Medicinal Chemistry
Protein N-terminal methyltransferase 1 (NTMT1) plays an important role in regulating mitosis and DNA repair. Here, we describe the discovery of a potent NTMT1 bisubstrate inhibitor 4 (IC50 = 35 ± 2 nM) that exhibits greater than 100-fold selectivity against a panel of methyltransferases. We also report the first crystal structure of NTMT1 in complex with an inhibitor, which revealed that 4 occupies substrate and cofactor binding sites of NTMT1.
