Évaluation de l’activité anxiolytique de la 4-phenyl-1,5-benzodiazepin-2-one

Les effets pharmacologiques de la 4-phenyl-1,5-benzodiazepin-2-one ont ete examines chez des souris par des tests comportementaux classiques (Test de planche a trous, Test de labyrinthe et Test de la tige tournante) et compares par rapport aux produits dont le potentiel anxiogenique ou anxiolytique sont connus. L’analyse de nos resultats a montre que la 4-phenyl-1,5-benzodiazepin-2-one et le diazepam ont augmente le temps passe dans les bras ouverts, tandis que la picrotoxin a entraine la diminution de ce temps. Considerant les resultats de l’evaluation de l’activite locomotrice, du comportement exploratoire et du comportement des animaux sur la tige tournante, le diazepam et la 4-phenyl-1,5-benzodiazepin-2-one ont influence de facon significative ces derniers par rapport a la picrotoxin et au vehicule. Ces donnees suggerent que la 4-phenyl-1,5- benzodiazepin-2-one possede une activite anxiolytique. Mots cles: 4-phenyl-1,5-benzodiazepin-2-one, activite anxiolytique, test de planche a trous, test de labyrinthe, test de la tige roulante.
