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 [ 10 ] cyclooxygenase-2 and prostacyclin (PGI 2 ) and increases nitric oxide ...

Independently of clinical symptoms, blood level of tryptophan or urinary metabolites such as 2-pyridone/N-methylnicotinamide ratio <2 or NAD/NADP ratio in red blood cells can diagnose pellagra. The diagnosis is confirmed by rapid improvements in symptoms after doses of nicotinamide (250–500 mg/day) or nicotinamide enriched food. [7]
Nicotinamide (INN, BAN UK [2]) or niacinamide (USAN US) is a form of vitamin B 3 found in food and used as a dietary supplement and medication. [3] [4] [5] As a supplement, it is used orally (swallowed by mouth) to prevent and treat pellagra (niacin deficiency). [4]
In enzymology, a nicotinamide N-methyltransferase (NNMT) (EC 2.1.1.1) is an enzyme that catalyzes the chemical reaction S-adenosyl-L-methionine + nicotinamide ⇌ {\displaystyle \rightleftharpoons } S-adenosyl-L-homocysteine + 1-methylnicotinamide.
Nicotinamide N-methyltransferase (NNMT) is an enzyme that in humans is encoded by the NNMT gene. [5] 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 .

N1-Methyl-2-pyridone-5-carboxamide (also known as 1-methyl-6-oxopyridine-3-carboxamide or nudifloramide and abbreviated as 2PY, 2-Py or NMPC) is one of a number of metabolic products of nicotinamide adenine dinucleotide (NAD) degradation.
