A new non-benzodiazepine compound proposed as a non-sedating anxiolytic was tested in the mouse exploratory model of anxiety. CGS 9896 significantly increased the number of light dark transitions at doses beginning at 7.5 mg/kg i.p. Analysis of general locomotor activity at these doses revealed no change in spontaneous motor activity in a photocell equipped activity monitor. Pretreatment with the benzodiazepine receptor antagonist, Ro15-1788, 10 mg/kg i.p., blocked the increase in light dark transitions produced by CGS 9896. These data support the interpretation that CGS 9896 acts as an anxiolytic through the benzodiazepine receptor, and appears to have no sedating properties within the anxiolytic dose range.
