| Research Abstract |
CV-159 is a selective blocker of Ca^<2+>/calmodulin and a free radical scavenger. Neuroprotective effects of CV-159 on energy metabolism of rat brain were investigated by phosphorous nuclear magnetic resonance spectroscopy. CV-159 was added to superfusate(10 nM-10μM, in vitro application), or was administered intraperitoneally(120μg/kg) to male Wistar rats 1 hr before decapitation(in vivo application). The recovery level of phosphocreatine, energetic buffer of ATP in living cells, 1 h after the reperfusion was significantly higher in intraperitoneally CV-159-administered rats than in the control. But with in vitro application, no neuroprotective effect was observed when brain slices were superfused with ACSF containing CV-159.
