Pyruvate markedly reduces neuronal death following transient global ischemia. In the present study, we investigated the possible neuroprotective effect of pyruvate in focal ischemia. Pyruvate (62.5-250 mg/kg) treatment, regardless of whether given intraperitoneally (ip) or intravenously (iv), decreased infarct volume by more than 50% in both transient (1 h) and permanent occlusion models. The infarct-reducing effects of pyruvate were maintained 14 days (d) after MCAO. Interestingly, higher doses failed to reduce the infarct size. Pyruvate administration also reduced motor deficits. Magnetic resonance (MR) spectroscopy revealed that protective doses of pyruvate, but not the non-protective doses, were associated with a reduction in the level of lactate compared with saline controls. Diffusion-weighted MR images further confirmed infarct reduction in pyruvate-treated rats. Pyruvate is an endogenous metabolite of glycolysis, and hence is unlikely to have serious side effects. Considering its substantial neuroprotective capacity in focal cerebral ischemia, a clinical trial is warranted.
