5-Amino-1MQ

5-Amino-1MQ is a small molecule inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme that has emerged as a key regulator of energy metabolism and adipose tissue function. While not a peptide, it is included in metabolic research compound catalogs due to its relevance to peptide-targeted metabolic pathways.

NNMT catalyzes the methylation of nicotinamide to 1-methylnicotinamide, consuming methyl donors and reducing the availability of nicotinamide for NAD+ biosynthesis. NNMT expression is elevated in adipose tissue of obese individuals and correlates with insulin resistance and metabolic dysfunction.

Research has shown that NNMT inhibition with 5-Amino-1MQ increases intracellular NAD+ levels, enhances cellular energy expenditure, and promotes white adipose tissue browning. Animal studies demonstrate reduced adiposity and improved metabolic parameters in diet-induced obesity models.

The compound represents a novel approach to metabolic regulation through modulation of NAD+ homeostasis rather than direct receptor agonism. Its effects on adipocyte metabolism and energy expenditure complement other metabolic research compounds and provide insight into the role of NAD+ metabolism in obesity and metabolic disease.
