Alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) glutamate receptor antagonists are of potential interest for the treatment of certain acute and chronic neurodegenerative diseases, including amyotrophic lateral sclerosis. Here, we describe the synthesis and pharmacological properties of(More)
The effects of thalidomide, a sedative, anti-inflammatory and immunosuppressive agent were studied in the MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) murine model of Parkinson's disease. The striatal levels of dopamine (DA) and of its main metabolites, 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) were measured both in the MPTP(More)
Riluzole, has previously been shown to be protective in animal models of Parkinson's disease in vivo. In the present study the effects of riluzole on the intrastriatal formation and accumulation of MPP(+), after i.p. injection of MPTP were tested in mice, using two different experimental protocols. In the first protocol, mice were treated with a single dose(More)
We have investigated whether riluzole, a compound that interferes with glutamatergic (GLUergic) transmission, would protect central dopaminergic (DAergic) neurones from 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced toxicity in the striatum in mice. MPTP decreased DA, 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) levels.(More)
The effects of riluzole and lamotrigine, two agents which interfere with the release of glutamate (GLU), and MK-801, a blocker of N-methyl-D-aspartate (NMDA) receptors, were compared in the model of methamphetamine-induced depletion of dopamine (DA) levels in mice. Repeated injections with methamphetamine (4 x 5 mg/kg i.p.) markedly decreased levels of DA,(More)
RPR 118723 ((8-chloro-5-methyl-2,3-dioxo-1,4-dihydro-5H-indeno[1, 2-b]pyrazin-5-yl) acetic acid) was previously reported to exhibit potent affinity for the glycine site of the N-methyl-D-aspartate (NMDA) receptor-channel complex in the nanomolar range (K(i)=3.1+/-0. 8 nM). We now report on the effects of RPR 118723 in two functional tests reflecting the(More)
The NMDA antagonist and neuroprotective effects of RPR 104632 (2H-1,2,4-benzothiadiazine-1-dioxide-3-carboxylic acid), a new benzothiadiazine derivative, with affinity for the glycine site of the NMDA receptor-channel complex are described. RPR 104632 antagonized the binding of [3H]5,7-dichlorokynurenic acid to the rat cerebral cortex, with a Ki of 4.9 nM.(More)
Metapramine, a pharmacological compound with antidepressant activity in humans, was tested for possible antiglutamatergic activity, in vitro. We investigated the effects of metapramine on the N-methyl-D-aspartic acid (NMDA) receptor complex, by determining whether this compound would interfere with the binding of(More)
