Abstract
|
|
|
|
The aim of the present study was examining the effects of some 1,3,5-trisubstituted-2-pyrazoline derivatives on depression, anxiety and spontaneous locomotor activity parameters of mice. None of the compounds was effective at 50 mg/kg dose whereas at 100 and 200 mg/kg, pyrazoline-benzoxazole derivative test compound 4a and pyrazoline-benzimidazole derivative test compound 4d in the series were exhibited significant antidepressant effects in modified forced swimming tests. These two pyrazolines decreased the immobility and increased the swimming times of mice without any change in climbing durations suggesting the antidepressant- like effects of the test compounds. In spite of significant antidepressant effect, none of the compounds changed the exploratory parameters in hole-board tests or total numbers of spontaneous locomotor activities in activity cage measurements at any of the applied doses. In other words, neither anxiolytic nor sedative effects induced by the test compounds. The results obtained from this study supported the previous findings reporting the antidepressant activities of pyrazoline derivative compounds. Exact mechanism of the antidepressant action exhibited in the present study need to be clarified with further detailed investigations.
