The potential neuroprotective value of ethyl pyruvate (EP) for the treatment of the striatal toxicity is largely unknown.We investigated whether EP promotes the survival of striatal neurons in a 3-nitropropionic acid (3-NP)-induced mouse model of Huntingtons disease (HD).EP (5, 10, 20, and 40 mg/kg/day, i.p.) was daily injected from 30 minutes before 3-NP intoxication (pretreatment) and from onset/progression/peak point of neurological impairment by 3-NP intoxication.
