In the present studies, using microiontophoretic techniques, the relative potencies of 3 indoleamine hallucinogens, psilocin, DMT, and bufotenine were tested upon 5HT neurons in the raphe (presynaptic neurons) and postsynaptic neurons in the ventral lateral geniculate and amygdala of the rat. Psilocin showed the greatest preferential inhibitory effect upon raphe as compared to postsynaptic neurons. DMT was intermdeiate and bufotenine had the least differential activity. This rank ordering correlates with the relative hallucinogenic potencies of these compounds: psilocin greater than DMT greater than bufotenine. The results support the hypothesis that low doses of indoleamine halluciogens act preferentially upon presynaptic serotonin receptors to inhibit raphe neurons, thus releasing postsynaptic neurons from a tonic inhibitory serotonergic influence.</p>","PeriodicalId":76387,"journal":{"name":"Psychopharmacology communications","volume":"1 6","pages":"619-29"},"PeriodicalIF":0.0,"publicationDate":"1975-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12244157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nisoxetine antagonized 6-hydroxydopamine-induced depletion of norepinephrine in mouse heart with an ED50 of 0.9 mg/kg but had no effect on p-chloroamphetamine-induced depletion of serotonin in mouse brain at doses up to 32 mg/kg. Using the antagonism of these depleting agents to estimate inhibition of uptake into noradrenergic and serotoninergic neurons, we compared nisoxetine to several known amine uptake inhibitors. The order of effectiveness in antagonizing 6-hydroxydopamine action was protriptyline greater than desmethylimipramine greater than EXP 561 greater than nisoxetine greater than nortriptyline greater than chlorpheniramine greater than desmethylchlorimipramine greater than imipramine greater than doxepin greater than amitriptyline greater than chlorimipramine, with fluoxetine and its N-demethylated metabolite (103947) having no effect. In blocking p-chloroamphetamine, the order of effectiveness was EXP 561 greater than fluoxetine greater than 103947 greater than chlorpheniramine greater than chlorimipramine, with desmethylchlorimipramine, protriptyline, and nortriptyline having marginal effects and nisoxetine and the other drugs no effect at the highest dose tested, 32 mg/kg.
