Natural Product Identification
Common Name1-Methylnicotinamide
Description1-Methylnicotinamide is a metabolite of nicotinamide and is produced primarily in the liver. It has anti-inflammatory properties (PMID 16197374 ). It is a product of nicotinamide N-methyltransferase [EC] In the pathway of nicotinate and nicotinamide metabolism (KEGG). 1-Methylnicotinamide may be an endogenous activator of prostacyclin production and thus may regulate thrombotic as well as inflammatory processes in the cardiovascular system (PMID: 17641676 ).
