The effects of phencyclidine (PCP) and its metabolites on serotonin (5-hydroxytryptamine, 5-HT) receptors were studied. PCP and its metabolites inhibited the uptake of [3H]5-HT and the binding of [3H]paroxetine in rat brain, while they failed to inhibit either [3H]5-HT binding to 5-HT1 receptors or [3H]ketanserin binding to 5-HT2 receptors. The trans-isomer of 4-phenyl-4-(I-piperidinyl)cyclo-hexanol (trans-4-PPC), the major metabolite of PCP, rather than PCP itself, inhibited [3H]5-HT uptake most potently. These results suggest that the serotonergic effects of PCP, in part, may be based on the effects of PCP metabolites on 5-HT uptake.

UI MeSH Term Description Entries
D007650 Ketanserin A selective serotonin receptor antagonist with weak adrenergic receptor blocking properties. The drug is effective in lowering blood pressure in essential hypertension. It also inhibits platelet aggregation. It is well tolerated and is particularly effective in older patients. 3-(2-(4-(4-Fluorobenzoyl)piperidinol)ethyl)-2,4(1H,3H)-quinazolinedione,R-41,468,R-41468,R 41,468,R 41468,R41,468,R41468

D010622 Phencyclidine A hallucinogen formerly used as a veterinary anesthetic, and briefly as a general anesthetic for humans. Phencyclidine is similar to KETAMINE in structure and in many of its effects. Like ketamine, it can produce a dissociative state. It exerts its pharmacological action through inhibition of NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE). As a drug of abuse, it is known as PCP and Angel Dust. 1-(1-Phenylcyclohexyl)piperidine,Angel Dust,CL-395,GP-121,Phencyclidine Hydrobromide,Phencyclidine Hydrochloride,Sernyl,Serylan,CL 395,CL395,Dust, Angel,GP 121,GP121
D011985 Receptors, Serotonin Cell-surface proteins that bind SEROTONIN and trigger intracellular changes which influence the behavior of cells.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
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.

D012701 Serotonin A biochemical messenger and regulator, synthesized from the essential amino acid L-TRYPTOPHAN. In humans it is found primarily in the central nervous system, gastrointestinal tract, and blood platelets. Serotonin mediates several important physiological functions including neurotransmission, gastrointestinal motility, hemostasis, and cardiovascular integrity. Multiple receptor families (RECEPTORS, SEROTONIN) explain the broad physiological actions and distribution of this biochemical mediator. 5-HT,5-Hydroxytryptamine,3-(2-Aminoethyl)-1H-indol-5-ol,Enteramine,Hippophaine,Hydroxytryptamine,5 Hydroxytryptamine
