2-Amino-6-trifluoromethoxy benzothiazole (PK 26124) prevented convulsions induced in rodents by maximal electroshock, inhibitors of the synthesis of gamma-aminobutyric acid (GABA) and ouabain, but was inactive against seizures provoked by GABA antagonists, unlike diazepam, chlordiazepoxide, phenobarbital and valproic acid. 2-Amino-6-trifluoromethoxy(More)
The aim of the present study was to analyse whether riluzole, a compound that interacts with the voltage-dependent sodium channel and impairs glutamatergic transmission, would exhibit a neuroprotective activity in a model of Parkinson's disease in the rat. Impaired skilled forelimb use, circling behavior, and altered dopaminergic metabolism of the(More)
The evidence that betaA4 is central to the pathology of Alzheimer's disease (AD) came from the identification of several missense mutations in the amyloid precursor protein (APP) gene co-segregating with familial AD (FAD). In an attempt to study the proteolytical processing of mutated human APP in vivo, we have created transgenic mice expressing the human(More)
This study compares certain behavioural consequences of partial and complete unilateral lesions of the dopaminergic mesotelencephalic system. We investigated skilled forelimb use, rotations induced by apomorphine and amphetamine, and dopaminergic metabolism of the nigrostriatal system of rats that had received a unilateral injection of 6-hydroxydopamine(More)
PK 8165, a new quinoline derivative, has a good affinity for brain type benzodiazepine binding sites and an anticonflict activity in the Vogel Test. However, contrarily to classical benzodiazepines (BZ) this compound is devoid of anticonvulsant and sedative properties. As biochemical studies suggested that PK 8165 is a partial agonist for BZ receptors, its(More)
