We studied the motor response induced by the administration of the AMPA receptor antagonist, NBQX (2,3-dihydroxy-6-nitro-7-sulfamoylbenzo[f]quinoxaline(1H,4H)dione sodium salt), in two parkinsonian monkeys and its interaction with the selective D-2 dopamine receptor agonist, (+)-PHNO [(+)-4-propyl-9-hydroxynaphthoxazine], and the partial dopamine D-1 receptor agonist, CY 208-243 [(-)-4,6,6a,7,8,12b-hexahydro-7-methyl-indolo[4,3a-b]phen anthyxidine].
NBQX treatment did not reverse the parkinsonism or change the responses previously induced by dopamine agonists. These results do not support an antiparkinsonian effect of the AMPA receptor antagonist, NBQX.
In addition they indicate that there is no functional interaction between AMPA and dopamine receptors in monkeys with a substantia nigra lesion.
