3-Nitropropionic acid (3-NP) causes severe neurotoxicity in animals, which depicts Huntington's disease (HD) in humans. Embelin, the main active constituent of Embelia ribes, has been reported to possess various pharmacological actions, mainly anti-inflammatory, antioxidant, anticonvulsant and neuroprotective. The aim of the present study was to evaluate the neuroprotective effect of embelin against 3-NP induced experimental HD in rats. Adult Wistar rats were pretreated with vehicle/embelin (10 and 20mg/kg p.o.) for 7 days. From 8th day onwards, embelin was co-treated with 3-NP (15mg/kg, i.p.) for 7 days. At the end of the treatment schedule, animals were evaluated for behavioral alterations and brain homogenates were used for estimation of oxidative stress parameters (lipid peroxidation, reduced glutathione, catalase and glutathione-S-transferase). 2,3,5-Triphenyl tetrazolium chloride (TTC) stained brain slices were used for lesion size measurement. Administration of 3-NP significantly altered the behavioral and neuronal antioxidant status and caused significant neuronal damage in striatal region. Embelin, at both the tested doses, caused a significant reversal of behavioral and antioxidant status alterations and reversed the striatal neuronal damage induced by 3-NP. These findings suggest the neuroprotective effect of embelin against HD. The observed protective effect might be attributed to the antioxidant properties of embelin.
