Abstract
THE recent work of Knox and Grossman1 has shown the existence of a new metabolite of nicotinic acid. They produced evidence that N-methylnicotinamide was oxidized by enzymes in the liver of the rabbit to N-methyl-2-pyridone-5-carboxylamide, and isolated that compound from the urine of human subjects who had been given daily doses of 0·6–0·9 gm. nicotinamide.
