| Abstract | We investigated the neuroprotective efficacy of the P-type Ca2+ channel antagonist daurisoline against electroshock-induced convulsions in rats and mice, hypoxic/hypoglycemic-induced damage in rat hippocampal slices and brain damage induced by occlusion of the middle cerebral artery (MCA) in rats. Daurisoline applied intravenously (i.v.) (bolus of 1–60 mg/kg) reduced the spontaneous activity of rat cerebellar Purkinje cells in a dose-dependent manner, a result demonstrating activity in the brain with systemic administration of the compound. While this effect reversed rapidly in about 10–20 min following bolus-application of the drug at doses of up to 30 mg/kg, a dose of 60 mg/kg consistently induced a depression of respiration followed by death of the animals. Daurisoline administered at 10–30 mg/kg did not prevent electroshock-induced convulsions in mice or rats, nor did it reduce neuronal damage in hippocampal slices induced by a hypoxic/hypoglycemic insult in vitro or by MCA occlusion in vivo. These observations do not support the hypothesis that P-type Ca2+ channels are promising drug targets for the acute treatment of epileptic convulsions and/or ischemic stroke. |
