5-Amino-1MQ (5-amino-1-methylquinolin-1-ium iodide, CAS 42464-96-0) is a synthetic quinolinium small molecule and selective substrate-site inhibitor of nicotinamide N-methyltransferase (NNMT), with a reported IC₅₀ of 1.2 μM. It is studied in vitro for its effects on the NAD⁺ salvage pathway, methionine cycle flux, and metabolic enzyme activity in cell culture models. Supplied by NexPept as powder for in vitro laboratory research use.

In Vitro Research Context
NNMT inhibition / NAD⁺ salvage pathway — laboratory use only
NNMT inhibition / NAD⁺ salvage pathway — laboratory use only
5-Amino-1MQ selectively occupies the substrate binding site of nicotinamide N-methyltransferase (IC₅₀ = 1.2 μM), blocking the enzyme’s N-methylation of nicotinamide. Substrate-site targeting distinguishes it from cofactor-competitive inhibitors.
NNMT competes with NAMPT for nicotinamide substrate. In vitro inhibition by 5-Amino-1MQ is studied for its effects on nicotinamide flux and intracellular NAD⁺ pool dynamics in metabolic cell culture models.
NNMT consumes S-adenosylmethionine (SAM) as a methyl donor during nicotinamide methylation. Inhibition preserves SAM availability, affecting transmethylation reactions throughout the methionine cycle in cell models.
In vitro studies have investigated 5-Amino-1MQ in adipogenesis models, including reduced lipogenesis in 3T3-L1 cells (EC₅₀ = 30 μM) and decreased 1-methylnicotinamide levels (EC₅₀ = 2.3 μM), as well as in skeletal muscle cell regeneration and metabolic enzyme activity research.
Research context: 5-Amino-1MQ is used as a tool compound in preclinical cell culture research investigating NNMT enzyme activity and its downstream effects on NAD⁺ metabolism and cellular methylation flux.
