title: [Effects of NC-1100, a calcium channel blocker, on experimental cerebral ischemia/anoxia in rodents].
abstract: The anti-ischemic and anoxic effects of NC-1100, a piperazine type calcium channel blocker, were investigated in various cerebral ischemia and anoxia models in mice, gerbils and guinea pigs. Minimal effective doses of NC-1100 were 8 mg/kg, i.p. and 30 mg/kg, p.o. for KCN-induced anoxia; 16 mg/kg, i.p. for decapitation-induced gasping; 30 mg/kg, i.p. for cerebral ischemia induced by occlusion of bilateral carotid arteries in gerbils; and 10 microM for the in vitro ischemic model in hippocampal slices. Moreover, NC-1100 attenuated the disturbance of cerebral energy metabolism induced by decapitation in mice. These results suggest that NC-1100 has a cerebral protective effect, and that attributable to its ability to improve the cerebral energy metabolism disturbance.
