Agonist1
N -methyl- D -aspartic acid or N -methyl- D -aspartate ( NMDA ) is an amino acid derivative that acts as a specific agonist at the NMDA receptor mimicking the action of glutamate , the neurotransmitter which normally acts at that receptor. (wikipedia.org)
Water-soluble1
[2] [3] NMDA is a water-soluble D -alpha-amino acid - an aspartic acid derivative with an N -methyl substituent and D - configuration - found across Animalia from lancelets to mammals . (wikipedia.org)

Kynurenic acid3
The pathway is named for the first intermediate, Kynurenine , which is a precursor to kynurenic acid and 3-hydroxykynurenine . (cloudfront.net)
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). (cloudfront.net)
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. (cloudfront.net)
NMDA3
