Research Abstract |
Fructose 1,6-diphophate is an intermediate substrate of glycolysis. It is a known neuroprotectant and acts as energy metabolite and a radical scavenger. The neuroprotective capacity of FDP was studied using 31P-nuclear magnetic resonance spectroscopy (^<31>P-NMR). The state of energy metabolism during ischemia-reperfusion insult was evaluated by 31P-NMR. The recovery of phosphocreatine, energetic buffer of ATP in living cells, was significantly higher when brain slices were superfused with 5 mM FDP. The series of our experiments, including 31P-NMR and electron spin resonance spectroscopy, indicated that FDP functions as a neuroprotectant not only as an energy metabolite of glycolysis but also as a radical scavenger.
