Metabolite Identification
Common NameN1-Methyl-4-pyridone-3-carboxamide
DescriptionN1-Methyl-4-pyridone-3-carboxamide, also known as 5-aminocarbonyl-1-methyl-4(1H)-pyridone, belongs to the class of organic compounds known as nicotinamides. These are heterocyclic aromatic compounds containing a pyridine ring substituted at position 3 by a carboxamide group. NN1-Methyl-4-pyridone-3-carboxamide (4PY ) is a normal human metabolite (one of the end products of nicotinamide-adenine dinucleotide (NAD) degradation). N1-Methyl-4-pyridone-3-carboxamide is an extremely weak basic (essentially neutral) compound (based on its pKa). N1-methyl-4-pyridone-3-carboxamide can be biosynthesized from 1-methylnicotinamide; which is mediated by the enzyme aldehyde oxidase. In humans, N1-methyl-4-pyridone-3-carboxamide is involved in nicotinate and nicotinamide metabolism. N1-Methyl-4-pyridone-3-carboxamide is a potentially toxic compound. Uremic toxins tend to accumulate in the blood either through dietary excess or through poor filtration by the kidneys. As a uremic toxin, this compound can cause uremic syndrome.
