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.[1][2][3][4] The presence of 2PY in human blood serum can be an indication of poor kidney performance or chronic kidney disease.[2][3] 2PY has been identified as a product of the metabolism of caffeine and niacin.[5]

2PY's molecular formula is C₇H₈N₂O₂ and its molecular weight 152.153 g/mol.[2]
