L-689,560 is a very potent antagonist at the glycine-NMDA site. The N-methyl-D-aspartate (NMDA) subtype of excitatorynamino acid receptor has been proved adequately that its relevant antagonists can reduce ischaemic brain damage (particularly in experimental models of focal cerebral ischaemia).
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].
Clinical trial: So far, no clinical study has been conducted.
