The endogenous cannabinoids (endocannabinoids) anandamide and 2-arachidonylglycerol increased cell viability in cerebral cortical neuron cultures subjected to 8 h of hypoxia and glucose deprivation. This effect was observed at nanomolar concentrations, was reproduced by a non-hydrolyzable analog of anandamide, and was unaltered by CB1 or CB2 cannabinoid receptor antagonists. Like synthetic cannabinoids, endocannabinoids can protect neurons from hypoxic injury, and may represent endogenous neuroprotective molecules in cerebral ischemia.
