Cerebral ischemia of 5 min duration was induced in unanesthetized Mongolian gerbils by bilateral occlusion of the carotid arteries. The extent of ischemic injury was assessed behaviorally by measuring the increases in locomotor activity following ischemia and by a histopathological assessment of the extent of CA1 hippocampal pyramidal cell injury and loss 5 days after ischemia. The A2a adenosine receptor selective antagonists 8-(3-chlorostyryl) caffeine (CSC; 0.1 mg/kg i.p.) and 4-amino-1-phenyl[1,2,4]-triazolo[4,3-a] quinoxaline (CP 66,713; 0.1 mg/kg i.p.) reduced the extent of ischemia-induced injury. An A1 selective receptor antagonist, 8-cyclopentyl-1,3-dipropylxanthine (DPCPX; 1.0 mg/kg i.p.), enhanced ischemia-evoked injury. These results suggest that adenosine A2a receptor antagonists may be useful for the prevention of cerebral injuries resulting from stroke or cardiac arrest.
