1-Methylnicotinamide
1-Methylnicotinamide (1-MNA, trigonellamide) is a prototypic organic cation. 1-Methylnicotinamide is the methylated amide of nicotinamide (niacinamide, vitamin B3).
1-Methylnicotinamide is an endogenic substance that is produced in the liver when nicotinamide is metabolized. It is a typical substance secreted in the kidney. It participates in the nicotinamide salvage pathway within the NAD+ (nicotinamide adenine dinucleotide) metabolic pathway, thereby contributing to optimizing NAD+ levels.
To date, the highest natural concentration of 1-methylnicotinamide has been found in the alga Undaria pinnatifida (3.2 mg/100 g of dried algae) and green tea leaves (3 mg/100 g of product). Other products with notable 1-MNA content include celery (1.6 mg/100 g of product), Chinese black mushrooms (shiitake, 1.3 mg/100 g), and fermented soybeans (natto, 1.0 mg/100 g).
1-Methylnicotinamide can be produced in the liver by nicotinamide N-methyltransferase (NNMT). The reaction takes place during the metabolism of NAD+ (nicotinamide adenine dinucleotide). NNMT is also present in brain tissue, adipose tissue, muscle tissue, kidneys, and skin.
NNMT (nicotinamide N-methyltransferase) is an enzyme that in humans is encoded by the NNMT gene. NNMT catalyzes the methylation of nicotinamide and similar compounds using the methyl donor S-adenosyl methionine (SAM-e) to produce S-adenosyl-L-homocysteine (SAH) and 1-methylnicotinamide. NNMT is highly expressed in the human liver.
Scientific research highlights numerous therapeutic and health-promoting properties of 1-MNA, including vascular protective, anticoagulant, anti-atherosclerotic, anti-inflammatory, neuroprotective, and endurance-enhancing effects.
1-MNA exerts beneficial effects on blood vessels through its action on the vascular endothelium. It improves the bioavailability of nitric oxide (NO), which is crucial for vasodilation, and regulates the activity of endothelial nitric oxide synthase (eNOS), the enzyme responsible for NO synthesis.
These effects have been demonstrated in both in vivo and in vitro studies. Oral administration of 1-MNA has been shown to increase the diameter of the brachial artery (as measured by flow-mediated dilation, FMD) and stimulate NO release from human endothelial cells in both healthy individuals and those with hypercholesterolemia increased.
