The purpose of the present study was to examine the dose-response relationship and the therapeutic time window for the synthetic nonpsychotropic cannabinoid (HU-211) as a neuroprotective agent in transient, severe forebrain ischemia in the rat. Adult Sprague-Dawley rats were subjected to 20 min common carotid artery occlusion (CCAo) 24 h after coagulation(More)
HU-211, a nonpsychotropic cannabinoid and a noncompetitive NMDA antagonist, was tested in a global ischemia model in the Mongolian gerbil. Male Mongolian gerbils underwent a 10-min bilateral common carotid artery occlusion. HU-211, administered i.v. at 4 mg/kg, 30 min postischemia, induced statistically significant neuroprotection of the CA1 subfield of the(More)
The interaction of 7-hydroxy-delta6-tetrahydrocannabinol 1,1-dimethylheptyl (Dexanabinol: HU-211), a novel NMDA receptor antagonist, with the dopaminergic system was examined using in vitro and in vivo systems. HU-211 (50 or 100 microM) inhibited the binding of [3H]R(+)-8-chloro-2,3,4,5-tetrahydro-3-methyl-5-phenyl-1H-3-benzazepi n-7-ol hydrochloride(More)
The novel tricyclic-terpenoid type cannabinoid, HU-211, was tested in gerbils and rats for protection against the effects of cerebral ischemia. Our transient ischemic models in gerbils and rats are based on the protection afforded against the lethal effects of global ischemia. HU-211 gave over 30% protection, by i.v. administration. The optimal dose ranges(More)
