Recently, it has been reported that Na+/H+ exchanger (NHE) inhibitors demonstrated protective effects on ischemia/reperfusion brain injury in animal models. However, the mechanisms by which the neurons were protected against ischemic insult remain unclear. To reveal the cellular mechanism of the NHE inhibitor on the neuronal death, we examined the effects of a selective NHE inhibitor, SM-20220 (N-[aminoiminomethyl]-1-methyl-1H-indole-2-carboxamide methanesulfonate), on glutamate-induced neuronal death in rat cortical culture.
