Description
5-Amino-1-methylquinolinium (5-Amino-1MQ) is a selective, membrane-permeable small-molecule inhibitor of nicotinamide N-methyltransferase (NNMT), the enzyme responsible for methylating nicotinamide to 1-methylnicotinamide. By blocking NNMT activity, 5-Amino-1MQ has been shown in preclinical cell and animal studies to elevate intracellular SAM and NAD⁺ pools, resulting in enhanced SIRT1/AMPK activity and inhibition of adipogenesis. Investigators have employed it as a tool compound to study the intersection of one-carbon metabolism, epigenetic programming, and energy homeostasis in white adipose tissue models.
Dorado Research offers 5-Amino-1MQ as a high-purity lyophilized powder verified by NMR and LC-MS, suitable for dissolution in DMSO or aqueous co-solvents for in vitro assay use. The compound is intended exclusively as a biochemical research tool for qualified laboratory applications, including enzyme inhibition kinetics, transcriptomic profiling, and metabolic flux analysis. For laboratory research use only. Not for human or veterinary use.
