| In Vitro | Pagoclone has high and approximately equivalent affinity (Ki values=0.7-9.1 nM) for recombinant human GABAA receptors containing either an α1, α2, α3 or α5 subunit. Pagoclone has significant agonist activity at all four diazepam-sensitive GABAA receptor subtypes, with EC50 of 3.1-6.6 nM[1]. |
| In Vivo | Pagoclone (3 mg/kg, p.o.) has significant anxiolytic-like activity, but at all three doses tested (0.3, 1 and 3 mg/kg p.o.) it produces a significant reduction in the total distance travelled. Pagoclone (3 mg/kg, p.o.) produces a dose-dependent increase in time spent on the open arms compared to control. Pagoclone (1, 3 or 10 mg/kg) lowers the cumulative chain-pulling response in the response sensitivity test. Plasma pagoclone concentrations are dose-dependent but not linear, with plasma concentrations of pagoclone being 0.4±0.1, 1.1±0.2 and 2.2±0.2 ng/mL, respectively. Pagoclone (0.3, 1 or 3 mg/kg) reduces locomotor activity in rats in a dose dependent manner[1]. |
| Animal Admin | The rat chain-pulling assay is a test for sedation. In brief, food-deprived PVG rats (250-300 g, n=12/group) are trained on a random probability interval schedule of 60 s following which animals are given doses of either vehicle (0.5% methyl cellulose, 1 mL/kg p.o.), pagoclone (1, 3 or 10 mg/kg p.o.) or, as a positive control, diazepam (10 mg/kg p.o.). Immediately after dosing, animals are placed in the operant box and the rates at which rats pulled a chain for a food reward are recorded over a 60 min period. Data is expressed as a mean percentage of the baseline chain pulls per minute and then analysed using an ANOVA followed by Dunnett's t-tests to compare each treatment group to the vehicle control group. |
