Para-halogenated phenethylamines: similar serotonergic effects in rats by different mechanisms. 1980

R S Sloviter, and J D Connor, and B P Damiano, and E G Drust

The serotonin (5-HT) behavioral syndrome in rats served as a model to test for possible acute serotonergic effects of para-halogenated phenethylamines. p-Chloro-, p-chloro-beta-methyl-, p-fluoro-, p-bromo-, and p-iodophenethylamine produced the same 5-HT behavioral syndrome as did p-chloroamphetamine, but unlike the latter did not deplete brain 5-HT 3 days after injection. Pretreatment of rats with the 5-HT depletor p-chlorophenylalanine (pCPA)( prevented the serotonergic effects of both chloro-derivatives, and partially prevented the effects of bromo- and iodophenethylamine. 5-hydroxytryptophan restored the behavioral responses to these compounds in pCPA-pretreated rats. pCPA treatment did not prevent the behavioral effects of p-fluorophenethylamine. Similarly, zimelidine, a 5-HT uptake inhibitor, prevented the serotonergic behavioral effects of all compounds tested except p-fluorophenethylamine. Taken as a group, para-halogenated phenethylamines are short-acting serotonergic compounds which, unlike p-chloroamphetamine, do not produce long-lasting depletion of brain 5-HT. p-Chlorophenethylamine and its beta-methyl analog apparently activate central 5-HT receptors indirectly, i.e., by 5-HT release; p-fluorophenethylamine is a direct 5-HT agonist. The p-bromo- and p-iodo-derivatives apparently possess both properties.

D008297	Male		Males
D009638	Norepinephrine	Precursor of epinephrine that is secreted by the ADRENAL MEDULLA and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers, and of the diffuse projection system in the brain that arises from the LOCUS CERULEUS. It is also found in plants and is used pharmacologically as a sympathomimetic.

D001923	Brain Chemistry	Changes in the amounts of various chemicals (neurotransmitters, receptors, enzymes, and other metabolites) specific to the area of the central nervous system contained within the head. These are monitored over time, during sensory stimulation, or under different disease states.	Chemistry, Brain,Brain Chemistries,Chemistries, Brain

D004298	Dopamine	One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
