Abstract：
:The actions of iontophoretically applied quipazine (QPZ) and 6-chloro-2-[1-piperazinyl]-pyrazine (CPP) were compared with those of serotonin (5-HT) on rat spinal motoneurones. QPZ and CPP qualitatively resembled 5-HT in that both facilitated single unit activity evoked by glutamate. Like 5-HT, the facilitation they produced could be antagonized by metergoline or methysergide. These observations are compatible with the suggestion that the actions of QPZ and CPP are mediated by 5-HT receptors. In rats pretreated with the neurotoxin 5,7-dihydroxytryptamine (5,7-DHT), QPZ and CPP remained effective in facilitating the glutamate evoked activity, whereas p-chloroamphetamine (PCA), a known releaser of 5-HT, was without effect. In contrast, PCA produced a long lasting facilitation in untreated rats. These data, taken together, suggest that QPZ and CPP are direct agonists at 5-HT receptors, but do not preclude the possibility that they might also act indirectly.
