The non-psychotropic cannabinoid (+)-(3S,4S)-7-hydroxy-DELTA6-tetrahyd
rocannabinol 1,1-dimethylheptyl (HU-211), a stereoselective inhibitor
of the N-methyl-D-aspartate (NMDA) receptor, protects primary cultures
of rat forebrain against NMDA receptor-mediated neurotoxicity. Cell m
ortality produced by exposure for 10 min to NMDA or glutamate was redu
ced to approximately 18 or 27%, respectively, by application of 50 muM
HU-211 for 10-15 min during or after exposure of cultures to excitato
ry amino acid. This effect of HU-211 was dependent on its concentratio
n (EC50 = 8.7 +/- 4 muM). HU-211 also reduced the toxicity induced by
brief exposure (10 min) to kainate or quisqualate, though less effecti
vely. HU-211 may therefore prove useful as a non-psychoactive drug tha
t protects against neurotoxicity mediated by the NMDA receptor.
