Overview

5-Amino-1MQ (5-amino-1-methylquinolinium) is a small-molecule quinolinium derivative studied as a selective, substrate-competitive inhibitor of nicotinamide N-methyltransferase (NNMT). It consists of a methylated quinolinium ring bearing a 5-amino substituent.

NNMT is an enzyme that methylates nicotinamide using S-adenosylmethionine (SAM) as a methyl donor, a reaction connected to NAD⁺ salvage pathways and cellular methylation balance. By inhibiting NNMT, 5-Amino-1MQ has been examined in research for its influence on these interconnected metabolic pathways.

Because of its interaction with NNMT and its relevance to NAD⁺ metabolism and methylation dynamics, 5-Amino-1MQ has become a frequently studied compound in laboratory research examining cellular energy metabolism, adipocyte biology, and metabolic regulation. Supplied as a research-grade 50 mg preparation, this compound is intended solely for laboratory and in-vitro investigation.

Research Background

Scientific investigations have examined 5-Amino-1MQ across experimental models evaluating NNMT enzyme activity, NAD⁺ salvage flux, and cellular methylation balance.

NNMT catalyzes the methylation of nicotinamide, producing 1-methylnicotinamide (1-MNA) while consuming SAM. Research suggests that inhibition of NNMT by 5-Amino-1MQ may reduce 1-MNA formation, increase the availability of SAM for other methylation reactions, and free nicotinamide for recycling through the NAMPT pathway toward NAD⁺ synthesis.

Experimental models have explored 5-Amino-1MQ in relation to adipocyte energetics, lipid handling, and insulin signaling. In preclinical research using diet-induced obesity models, investigators reported that NNMT inhibition was associated with reductions in white adipose tissue mass and changes in metabolic parameters.

In animal studies, researchers observed reductions in body weight and adipocyte size following administration of 5-Amino-1MQ, with reported decreases in total fat mass and minimal changes in lean mass during controlled research protocols.

Because of its selective interaction with NNMT and its connections to NAD⁺ metabolism and methylation pathways, 5-Amino-1MQ continues to be studied as a model compound in research examining metabolic regulation, adipose tissue biology, and cellular energy pathways.
