5-Amino-1MQ (5-amino-1-methylquinolinium) is a synthetic small molecule that selectively inhibits Nicotinamide N-methyltransferase (NNMT). NNMT is an enzyme that methylates nicotinamide (vitamin B3) using S-adenosylmethionine (SAM) as a methyl donor. In states of obesity and metabolic dysfunction, NNMT is often overexpressed in adipose tissue, depleting nicotinamide and reducing NAD+ availability.

By inhibiting NNMT, 5-Amino-1MQ may spare nicotinamide for NAD+ synthesis, thereby activating SIRT1 (Sirtuin 1) pathways associated with mitochondrial biogenesis and fat oxidation. Preclinical studies indicate that NNMT knockdown or inhibition can protect against diet-induced weight gain and improve metabolic parameters without reducing food intake.

This product contains 5-Amino-1MQ in lyophilized (freeze-dried) powder form, requiring reconstitution before use.
