Abstract— N'‐Formylkynurenine, a photochemical breakdown product of tryptophan in proteins, was exposed to sunlight or simulated sunlight at neutral pH. N‐Formylanthranilic acid and 4‐hydroxyquinoline were identified in the reaction products. Neither has been previously described as a photo‐oxidation product of tryptophan‐containing compounds. They were not found after photo‐oxidation of glycyltryptophan or tryptophylglycine, although the indole ring was broken in both compounds.
