Cell-potent and Selective Inhibitors for Nicotinamide N-methyltransferase
Highly selective and potent inhibitors targeting nicotinamide N-methyltransferase (NNMT) offer a new therapeutic strategy for a range of diseases including cancer and metabolic disorders.
NCS: Researchers at Purdue University have synthesized a series of cell-potent and selective inhibitors of nicotinamide N-methyltransferase (NNMT) that can be used to treat cancer, metabolic and neurodegenerative diseases. NNMT plays an important role in regulating both epigenetics and metabolism by methylating nicotinamide. Elevated levels of NNMT have been associated with diseases like cancer, liver disease, diabetes, and obesity. The most potent compound (IC50 =3.4 nM) synthesized by the Purdue researchers had an IC50 value of 100 nanomolar for inhibiting N-methylated Nicotinamide in cells, over 1000-fold selectivity for NNMT compared to related methyltransferases. Moreover, cell-potent NNMT inhibitors exhibit a favorable pharmacokinetics profile.
