Abstract

Nicotinamide N-oxide is a major nicotinamide catabolite in mice but not in humans and rats. A high-performance liquid chromatographic method for the simultaneous measurement of nicotinamide, nicotinamide N-oxide, N(1)-methyl-2-pyridone-5-carboxamide, and N(1)-methyl-4-pyridone-3-carboxamide in mice urine was developed by modifying the mobile phase of a reported method for measurement of nicotinamide N-oxide.
