1-Methylnicotinamide (trigonellamide) is a prototypic organic cation. [1] 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.

Occurrence

The highest natural concentration of 1-methylnicotinamide found so far is in the alga Undaria pinnatifida. [2] 1-Methylnicotinamide is also present in the Judas' ear fungus and in green tea. [2]

Extraction and production

1-Methylnicotinamide can be produced in the liver by nicotinamide N-methyltransferase. The reaction takes place during the metabolism of NAD ( nicotinamide adenine dinucleotide).

NNMT (nicotinamide N-methyltransferase) is an enzyme that in humans is encoded by the NNMT gene. [3] 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. [4] NNMT is highly expressed in the human liver. [4]

Use

For a long time, 1-methylnicotinamide was considered a biologically inactive metabolite of nicotinamide. However, various studies show antithrombotic, [5] anti-inflammatory, [6] gastroprotective [7] and vasoprotective [7] properties.

1-Methylnicotinamide is an endogenous activator of prostacyclin synthesis and can therefore regulate thrombolytic[ check spelling] and inflammatory processes in the cardiovascular system. [8] It inhibits platelet-dependent thrombosis through a mechanism involving [9] cyclooxygenase-2 and prostacyclin and increases nitric oxide bioavailability in the endothelium. [7] [4]

Animal experiments with diabetic rats have shown that 1-methylnicotinamide has a positive effect on degenerative changes in the brain and cognitive performance can be thus longer maintained. [10]

Experiments with the nematode Caenorhabditis elegans showed that the addition of 1-methylnicotinamide can extend their lifespan. This may possibly be attributed to increased free radical binding and the resulting reduced oxidative stress. [11]

1-Methylnicotinamide is used in cosmetic products such as hair- and skincare products and as a dietary supplement. [12]
