| | Definition | ChEBI: A hydroxykynurenine that is kynurenine substituted by a hydroxy group at position 3. | | General Description | 3-Hydroxy-DL-kynurenine is a tryptophan metabolite with a molecular weight corresponding to 224Da. It is a chromophore or hydrophilic yellow compound present in the lens of the eye. 3-Hydroxy-DL-kynurenine is synthesized from kynurenine?by the action of enzyme kynurenine 3-monooxygenase (KMO). It is metabolized to 3-hydroxyanthranilic acid and xanthurenic acid in the presence of enzymes kynureninase and kynurenine aminotransferases, respectively. | | Biochem/physiol Actions | 3-Hydroxy-DL-kynurenine (3-HKYN) has antioxidant functionality and prevents lipid peroxidation in cerebral cortex. It may modulate synaptic neurotransmission. The levels of 3-HKYN is elevated in Huntington′s disease. However, its role in neurodegenerative diseases is still not understood well. Kynurenine metabolism is linked with glutamatergic neurotransmission and the level of 3-HKYN is linked to the pathophysiology of schizophrenia. |
