5-Amino-1MQ (5-Amino-1-methylquinolinium iodide) is a selective small-molecule inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme involved in nicotinamide methylation and cellular methyl-donor utilization pathways. By inhibiting NNMT activity, 5-Amino-1MQ modulates enzymatic processes associated with nicotinamide metabolism, methylation network regulation, and intracellular cofactor-associated signaling systems. Experimental investigations have examined the relationship between NNMT inhibition and regulatory pathways involving nicotinamide turnover, methylation dynamics, transcriptional control mechanisms, and downstream signal transduction processes.

Its well-characterized pharmacological profile has established 5-Amino-1MQ as a valuable research tool for studying NNMT enzyme biology, enzyme-inhibitor interactions, methylation pathway regulation, nicotinamide-associated metabolic networks, and structure-activity relationships involving NNMT-targeting compounds. Research applications include NNMT pharmacology, methyltransferase signaling studies, enzymatic regulation investigations, and mechanistic evaluation of nicotinamide methylation pathways.

5-Amino-1MQ is a quaternary ammonium compound and selective inhibitor of nicotinamide N-methyltransferase (NNMT), a methyltransferase enzyme that catalyzes the transfer of a methyl group from S-adenosylmethionine (SAM) to nicotinamide, producing 1-methylnicotinamide. By modulating NNMT activity, 5-Amino-1MQ influences enzymatic pathways associated with nicotinamide metabolism, methyl-donor utilization, and intracellular cofactor-associated regulatory networks. Experimental investigations have examined the relationship between NNMT inhibition and signaling pathways involving nicotinamide turnover, NAD+-associated metabolic systems, SIRT1-linked regulatory mechanisms, and transcriptional control processes. Additional studies have characterized the effects of NNMT inhibition on methylation pathway dynamics, enzyme-regulated signaling networks, and cellular regulatory systems influenced by nicotinamide metabolism. These characteristics have established 5-Amino-1MQ as a valuable research tool for investigating NNMT enzyme biology, enzyme-inhibitor interactions, methylation pathway regulation, nicotinamide-associated signaling processes, and mechanistic aspects of methyltransferase pharmacology. Supplied in 50 mg capsules. Independently third-party HPLC-tested; COA available per batch.

What enzyme does 5-Amino-1MQ inhibit?

5-Amino-1MQ selectively inhibits nicotinamide N-methyltransferase (NNMT), a methyltransferase enzyme that catalyzes the transfer of a methyl group from S-adenosylmethionine (SAM) to nicotinamide, producing 1-methylnicotinamide. Because NNMT occupies a central position within nicotinamide methylation pathways, it has become an important target for investigations involving enzyme regulation, methyl-donor utilization, cofactor-associated signaling networks, and methyltransferase pharmacology.

How does 5-Amino-1MQ differ from compounds such as NMN and NR in pathway research?

NMN and NR are commonly studied in relation to nicotinamide-associated metabolic pathways, whereas 5-Amino-1MQ acts through selective inhibition of NNMT. This distinct mechanism makes 5-Amino-1MQ a useful research tool for examining enzymatic regulation of nicotinamide turnover, methylation pathway dynamics, enzyme-inhibitor interactions, and regulatory processes associated with NNMT activity. Comparative investigations frequently utilize these compounds to explore different aspects of nicotinamide-related biochemical networks.

Why is 5-Amino-1MQ widely used in NNMT research?

5-Amino-1MQ possesses a well-characterized pharmacological profile and high selectivity for NNMT, making it a valuable reference compound for studies involving NNMT enzyme biology, methyltransferase pathway regulation, structure-activity relationships, and inhibitor-target interactions. Its established mechanism of action continues to support mechanistic investigations into nicotinamide methylation pathways and the broader role of NNMT within cellular regulatory networks.
