L-689,560 is a potent antagonist at the glycine-NMDA receptor site. | [Definition]
ChEBI: 4-[[anilino(oxo)methyl]amino]-5,7-dichloro-1,2,3,4-tetrahydroquinoline-2-carboxylic acid is a member of quinolines. | [Biological Activity]
Very potent antagonist at the glycine-NMDA site. Also available as part of the NMDA Receptor - Glycine Site Tocriset™ . | [in vitro]
l-689560 is described as one of the most potent nmda antagonists and [4'-3h]-l-689560 has been thought to be a highly specific radioligand for the glycine site. in consistent with the 5,7-disubstituted kynurenates, the tetrahydroquinolines are selective antagonists of glycine site nmda, l-689560 exhibiting at least 3 orders of magnitude selectivity versus the glutamate site [1]. | [in vivo]
mdl100748 with an ed50 of 83 mg kg-1 can prevent audiogenic seizures in susceptible mice after systemic injection. as a standard l689560, its subsequent analogues have been compared; the displacement of [3h] l689560 has often been used to displace that of [3h] glycine as an alternative assay. l701252, a quinones (the retention of a keto grouping at position 3), has been against l689560 binding (ic50 of 420 nm) and against seizures (ed50 of 4.1 mg kg-1) in dba/2 mice. a group of sulfonamide analogues of kynurenic acid are also in active among the 2-quinolone series. those of a series of 3,4-dihydroquinolones and tetrahydroquinolines with a nitrosubstituent at 3-position were selective antagonists at the nmda receptor glycine site if they bore a bulky grouping in the position 4. the compound with no substitution at position 4 was proved to be one of the most effective broad-spectrum antagonists against nmda and ampa receptors [2]. | [storage]
