N2 - The permanent middle cerebral artery occlusion (PMCAO) model was used to investigate the cerebroprotective effects of the synthetic cannabinoid, dexanabinol (HU-211). Dexanabinol is a noncompetitive N-methyl-D-aspartate antagonist, with antioxidant and anti-TNFα properties. Twenty hypertensive rats were subjected to PMCAO. Eight were given 4 mg/kg dexanabinol, i.v, 1 h after PMCAO, eight received vehicle and four were not injected. Five rats underwent sham surgery. Infarct volumes were assessed, as well as TNFα concentrations and NOS activity in brain homogenates. Dexanabinol significantly decreased infarct volumes. It also significantly lowered TNFα levels in the ipsilateral hemisphere although not to the level of sham operated rats. No effect could be demonstrated on NOS activity. In conclusion, dexanabinol may be a pluripotent cerebroprotective agent.
