Kynurenic acid5
- This pathway is important for its production of the coenzyme nicotinamide adenine dinucleotide (NAD+) and produces several neuroactive intermediates including quinolinic acid, kynurenine (KYN), kynurenic acid (KYNA), 3-hydroxykynurenine (3-HK), and 3-hydroxyanthranilic acid (3-HANA). (wikipedia.org)
- While quinolinic acid cannot pass the BBB, kynurenic acid, tryptophan and 3-hydroxykynurenine do and subsequently act as precursors to the production of quinolinic acid in the brain. (wikipedia.org)
