organic heterocyclic compound carboxylic acid 7-chlorokynurenic acid 0 223.00362 223.615 O=C(O)c1cc(O)c2ccc(Cl)cc2n1 C10H6ClNO3 reaxys:185645 Reaxys:185645 CHEBI:63965 pubmed:11224142 A quinolinemonocarboxylic acid that is quinaldic acid which is substituted by a hydroxy group at position 4 and by a chlorine at position 7. It is a potent NMDA glutamate receptor antagonist which antagonizes the strychnine-insensitive glycine site of the NMDA receptor. It also prevents neurodegeneration produced by quinolinic acid. 7-chloro-4-hydroxy-2-carboxyquinoline cas:18000-24-3 UAWVRVFHMOSAPU-UHFFFAOYSA-N InChI=1S/C10H6ClNO3/c11-5-1-2-6-7(3-5)12-8(10(14)15)4-9(6)13/h1-4H,(H,12,13)(H,14,15) 7-chloro-4-hydroxyquinoline-2-carboxylic acid 7-CKA chebi_ontology 7-chloro-4-hydroxyquinoline-2-carboxylic acid ChEMBL:216326 MESH:C057013 7-Cl-KYNA ChemIDplus:18000-24-3 lincs.smallmolecule:LSM-24944 CiteXplore:11224142 acid
