dc.description.abstractL-Deprenyl (Selegeline) introduced for use in parkinson's disease, is implicated to show beneficial effects in epilepsy, alzheimer's disease, cognition, depression and other age related neurological diseases. In this study, we investigated the CNS effects of L-deprenyl with special reference to epilepsy, anxiety and cognition and memory in mice. L-deprenyl (10, 20 and 40 mg/kg) showed a significant anticonvulsant activity against pentylenetetrazole (PTZ)- induced convulsions. Combination of L-deprenyl (10 mg/kg) with the sub-protective dose of diazepam (1 mg/kg) showed potentiation of the anticonvulsant effect. In the maximal-electroshock (MES)-induced convulsions, L-deprenyl (10 mg/kg) significantly delayed the onset and decreased the duration of extensor phase. Its combination with the lower dose of phenytoin (10mg/kg) showed potentiation in response compared to the per se effect of both the drugs. However, L-deprenyl did not show any protective effect in lithium-pilocarpine induced status epilepticus. Acute treatment with L-deprenyl had no effect on learning and memory. In chronic treatment, L-deprenyl per se showed no effect on learning and memory but did improve the condition in mice with scopolamine induced memory deficit. L-Deprenyl per se was anxiogenic though in combination with diazepam (1 mg/kg) it potentiated the antianxiety effect of the latter. The above observations suggest that in epilepsy, L-deprenyl might be acting partially by influencing the GABAA/benzodiazepine mechanism in the brain (similar to diazepam and phenytoin), and in cognition enhancing effect, the cholinergic system might be playing a role. Thus, L-deprenyl could prove to be an adjuvant in the antiepileptic therapy and beneficial in dementia associated with epilepsy.en_US
