Phencyclidine (PCP) inhibits dopamine (DA) uptake and acts as a noncompetitive N-methyl-D-aspartate antagonist by binding to PCP receptors. The PCP analog N-[1-(2-benzo(b)thiophenyl) cyclohexyl]piperidine (BTCP, GK13) is a potent DA uptake inhibitor, but has low affinity for PCP receptors. The behavioral effects of BTCP were compared with those of PCP, ketamine, MK-801 and cocaine. In mice, BTCP, like cocaine, produced locomotion, sniffing and gnawing; haloperidol blocked these effects. PCP, ketamine and MK-801 produced locomotion, sniffing, swaying and falling. PCP, ketamine and MK-801 produced generalization in rats discriminating either cocaine, PCP or MK-801 from saline. Like cocaine, BTCP produced generalization in cocaine-discriminating rats only; haloperidol partially antagonized this effect. In pigeons, PCP-like catalepsy was produced by ketamine and MK-801, but not by BTCP. N-methyl-D-aspartate-induced convulsions in mice were antagonized by PCP, ketamine and MK-801, but not by BTCP or cocaine. Thus, BTCP shared only cocaine-like behavioral effects with PCP, ketamine and MK-801. A DA antagonist reduced the effects of BTCP. Therefore, the cocaine-like behavioral effects of BTCP may be mediated primarily by DA uptake mechanisms. However, PCP receptors, but not DA uptake mechanisms, may mediate the cocaine-like behavioral effects of PCP, ketamine and MK-801, because their order of potency in producing these effects (MK-801 greater than PCP greater than ketamine) is consistent with their potency order at PCP receptors, but not at DA uptake sites.

D007649 Ketamine A cyclohexanone derivative used for induction of anesthesia. Its mechanism of action is not well understood, but ketamine can block NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE) and may interact with sigma receptors. 2-(2-Chlorophenyl)-2-(methylamino)cyclohexanone,CI-581,Calipsol,Calypsol,Kalipsol,Ketalar,Ketamine Hydrochloride,Ketanest,Ketaset,CI 581,CI581
D008774 Methylphenidate A central nervous system stimulant used most commonly in the treatment of ATTENTION DEFICIT DISORDER in children and for NARCOLEPSY. Its mechanisms appear to be similar to those of DEXTROAMPHETAMINE. The d-isomer of this drug is referred to as DEXMETHYLPHENIDATE HYDROCHLORIDE. Centedrin,Concerta,Daytrana,Equasym,Metadate,Methylin,Methylphenidate Hydrochloride,Phenidylate,Ritalin,Ritalin-SR,Ritaline,Tsentedrin,Hydrochloride, Methylphenidate,Ritalin SR
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
D010856 Columbidae Family in the order COLUMBIFORMES, comprised of pigeons or doves. They are BIRDS with short legs, stout bodies, small heads, and slender bills. Some sources call the smaller species doves and the larger pigeons, but the names are interchangeable.

D003042 Cocaine An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.

D003913 Dextroamphetamine The d-form of AMPHETAMINE. It is a central nervous system stimulant and a sympathomimetic. It has also been used in the treatment of narcolepsy and of attention deficit disorders and hyperactivity in children. Dextroamphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulating release of monamines, and inhibiting monoamine oxidase. It is also a drug of abuse and a psychotomimetic. d-Amphetamine,Curban,Dexamfetamine,Dexamphetamine,Dexedrine,Dextro-Amphetamine Sulfate,DextroStat,Dextroamphetamine Sulfate,Oxydess,d-Amphetamine Sulfate,dextro-Amphetamine,Dextro Amphetamine Sulfate,Sulfate, Dextroamphetamine,d Amphetamine,d Amphetamine Sulfate,dextro Amphetamine
D003986 Dibenzocycloheptenes A family of tricyclic hydrocarbons whose members include many of the commonly used tricyclic antidepressants (ANTIDEPRESSIVE AGENTS, TRICYCLIC).
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.

D006220 Haloperidol A phenyl-piperidinyl-butyrophenone that is used primarily to treat SCHIZOPHRENIA and other PSYCHOSES. It is also used in schizoaffective disorder, DELUSIONAL DISORDERS, ballism, and TOURETTE SYNDROME (a drug of choice) and occasionally as adjunctive therapy in INTELLECTUAL DISABILITY and the chorea of HUNTINGTON DISEASE. It is a potent antiemetic and is used in the treatment of intractable HICCUPS. (From AMA Drug Evaluations Annual, 1994, p279) Haldol
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.
