PEPTIDES4ALL 5-Amino-1MQ – Orally Active NNMT Inhibitor for Metabolic & Longevity Research
5-Amino-1MQ (5-amino-1-methylquinolinium) is a small-molecule NNMT (nicotinamide N-methyltransferase) inhibitor developed for the exploration of metabolic regulation, NAD⁺ preservation, and cellular longevity.
By suppressing NNMT activity — an enzyme that diverts nicotinamide away from NAD⁺ salvage — 5-Amino-1MQ helps maintain cellular NAD⁺ pools, enhance energy metabolism, and reduce adipose accumulation.
Elevated NNMT expression has been implicated in obesity, insulin resistance, fatty liver disease, and age-related metabolic dysfunction.
Through its selective inhibition mechanism, 5-Amino-1MQ supports improved mitochondrial function, glucose handling, and metabolic flexibility — positioning it as a valuable compound for obesity, metabolic health, and longevity research. PMC+1
Scientific Rationale & Evidence
-
Reversal of Diet-Induced Obesity — In high-fat diet mouse models, 5-Amino-1MQ significantly reduced adipose tissue mass and improved metabolic markers without affecting food intake. PMC
-
Improved Metabolic & Liver Pathology — In obese mice, combining 5-Amino-1MQ with a lean diet restored adiposity and liver pathology to lean control levels, suggesting synergy with dietary modulation. Nature
-
Mechanism: NAD⁺ Preservation — By inhibiting NNMT, 5-Amino-1MQ limits nicotinamide methylation (forming 1-methyl nicotinamide), thereby preserving nicotinamide availability for NAD⁺ salvage pathways. Peptide Sciences+1
-
Muscle Strength / Repair Effects — Recent insights show that in aged mice, treatment with 5-Amino-1MQ improved grip strength and enhanced recovery when combined with exercise, supporting its potential in muscle resilience research. NMN.com
