An excitory
amino acid isolated from the red alga Chondria armata. A structural
analog of kainic acid and domoic acid has been shown to be
responsible for the shellfish poisoning associated with eating certain
cultured blue mussels.

용도
Labelled Domoic Acid. Domoic Acid is an excitatory amino acid isolated from the red alga Chondria armata Okamura, Rhodomelaceae. Domoic acid shown to be responsible for amnesic shellfish poisoning ass
ociated with ingestion of certain cultured blue mussels. Domoic Acid is a structural analog of Kainic acid (K135000).
정의
ChEBI: A L-proline derivative that is L-proline substituted by a carboxymethyl group at position 3 and a 6-carboxyhepta-2,4-dien-2-yl group at position 4. It is an analog of kainic acid and is the neurotoxin associated with the a
nesic shellfish poisoning (ASP).
일반 설명
Domoic acid, a heterocyclic amino acid neurotoxin is synthesized by various marine algaes. It possess some structural similarity to kainic acid.
생물학적 활성
More potent and possibly more selective than kainate at kainate receptors, as demonstrated in electrophysiological studies.
Purification Methods
Domoic acid (~300 mg) is purifed on a Dowex1 column (3.5 x 40 mm, 200-400 mesh, acetate form), washed with H2O until neutral, then eluted with increasing concentrations of AcOH (8L) from 0 to 0.25M. The fraction containing domoic acid (in 50mL) is collected, evaporated to dryness under reduced pressure and recrystallised from aqueous EtOH. It is a glutamate and a Kainate receptor agonist.
