摘要
This study examines the ability of (+)-(3S,4S)-7-hydroxy-Delta(6)-tetrahydrocannabinol-1,1-dimethylheptyl (HU-211), a non-competitive NMDA receptor antagonist to: (1) rescue neurons in culture from injury evoked by sodium nitroprusside, hydrogen peroxide (H2O2) and oxygen glucose deprivation; and (2) scavenge reactive oxygen species in vitro. Qualitative and quantitative assessments of cell survival have indicated that: (1) Neuronal cell injury produced following deprivation of oxygen and glucose was significantly attenuated by 5 mu M HU-211. (2) Glial and neuronal cell damage induced by sodium nitroprusside was markedly ameliorated by 10 mu M HU-211. (3) HU-211 reduced protein oxidation initiated by gamma irradiation, and scavenged peroxyl radicals. (4) HU-211 carries an oxidation potential of 550 mV. These findings suggest that HU-211 holds a unique position among putative neuroprotectant agents in that it combines NMDA receptor antagonistic activity and free radical scavenging abilities in a single molecule.
