The effects of 5-HT1A-receptor agonists 8-hydroxy-2-(di-n-propylamino) tetralin (8-OH-DPAT) and gepirone, a 5-HT1A/5-HT2-receptor agonist 5-methoxy-N,N-dimethyltryptamine (5-MeODMT) and a 5-HT2-receptor agonist (+-)1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane ((+/)DOI) on the 5-HT1C-receptor-mediated exploratory hypoactivity in rats, induced by m-trifluoromethylphenylpiperazine (TFMPP) or m-chlorophenylpiperazine (m-CPP), were studied in the open field test. (+/-)DOI attenuated the effects of TFMPP and abolished those of m-CPP (not dose-dependently). 5-MeODMT showed a weak antagonistic action only at one, intermediate dose. The effects of TFMPP or m-CPP were not changed by 8-OH-DPAT or gepirone. At the same time, 8-OH-DPAT, gepirone, 5-MeODMT and (+/-)DOI themselves practically did not change the exploratory activity of rats. The obtained results permit an assumption that a functional interaction exists between 5-HT1C- and 5-HT2-receptors, but not between 5-HT1C- and 5-HT1A-ones.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008732	Methoxydimethyltryptamines	Compounds that contain the biogenic monoamine tryptamine and are substituted with one methoxy group and two methyl groups. Members of this group include several potent serotonergic hallucinogens found in several unrelated plants, skins of certain toads, and in mammalian brains. They are possibly involved in the etiology of schizophrenia.

D010879	Piperazines	Compounds that are derived from PIPERAZINE.
D011743	Pyrimidines	A family of 6-membered heterocyclic compounds occurring in nature in a wide variety of forms. They include several nucleic acid constituents (CYTOSINE; THYMINE; and URACIL) and form the basic structure of the barbiturates.
D011985	Receptors, Serotonin	Cell-surface proteins that bind SEROTONIN and trigger intracellular changes which influence the behavior of cells. Several types of serotonin receptors have been recognized which differ in their pharmacology, molecular biology, and mode of action.	5-HT Receptor,5-HT Receptors,5-Hydroxytryptamine Receptor,5-Hydroxytryptamine Receptors,Receptors, Tryptamine,Serotonin Receptor,Serotonin Receptors,Tryptamine Receptor,Tryptamine Receptors,Receptors, 5-HT,Receptors, 5-Hydroxytryptamine,5 HT Receptor,5 HT Receptors,5 Hydroxytryptamine Receptor,5 Hydroxytryptamine Receptors,Receptor, 5-HT,Receptor, 5-Hydroxytryptamine,Receptor, Serotonin,Receptor, Tryptamine,Receptors, 5 HT,Receptors, 5 Hydroxytryptamine
D000662	Amphetamines	Analogs or derivatives of AMPHETAMINE. Many are sympathomimetics and central nervous system stimulators causing excitation, vasopressin, bronchodilation, and to varying degrees, anorexia, analepsis, nasal decongestion, and some smooth muscle relaxation.
D000704	Analysis of Variance	A statistical technique that isolates and assesses the contributions of categorical independent variables to variation in the mean of a continuous dependent variable.	ANOVA,Analysis, Variance,Variance Analysis,Analyses, Variance,Variance Analyses
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.

D014151	Anti-Anxiety Agents	Agents that alleviate ANXIETY, tension, and ANXIETY DISORDERS, promote sedation, and have a calming effect without affecting clarity of consciousness or neurologic conditions. ADRENERGIC BETA-ANTAGONISTS are commonly used in the symptomatic treatment of anxiety but are not included here.
