Differential interactions of "prosexual" drugs with 5-hydroxytryptamine1A and alpha 2-adrenergic receptors.

Behavioral Neuroscience October 1, 1986 L L Kwong, E R Smith, J M Davidson et al. 38 citations

Radioligand binding studies were used to analyze the interactions of six "prosexual" drugs with 5-hydroxytryptamine1A (5-HT1A) and alpha 2-adrenergic receptors in rat brain membranes. Three drugs that facilitate seminal emissions and/or ejaculations [8-hydroxy-2-n-propylaminotetralin (8-OH-DPAT), 5-methoxy-dimethyltryptamine, and RDS-127] are potent and selective inhibitors of [3H]8-OH-DPAT...

Differential effects of 5-hydroxytryptamine1a selective drugs on the 5-HT behavioral syndrome.

Pharmacology, Biochemistry, and Behavior June 1, 1986 L M Smith, S J Peroutka 245 citations

The effects of 8-hydroxy-2-(di-n-propyl-amino) tetralin (8-OH-DPAT), 5-methoxy-N,N-dimethyltryptamine (5-MeODMT), buspirone and isapirone were examined at 5-hydroxytryptamine1A (5-HT1A) binding sites and on the 5-HT behavioral syndrome in the rat. 8-OH-DPAT, 5-MeODMT, buspirone and isapirone are all potent inhibitors of 3H-8-OH-DPAT binding to rat brain membranes (Ki values = 1.9-13 nM)....

A primate model for the study of hallucinogens.

Pharmacology, Biochemistry, and Behavior February 1986 R F Schlemmer, J M Davis

An animal model for studying the actions of hallucinogenic drugs using primate social colonies is presented. Although hallucinogens induce a number of behavioral changes in this paradigm, one emergent behavior, limb jerks, appears to be selectively induced by three classes of hallucinogens in doses which correlate with those reported to be hallucinogenic in humans. Several non-hallucinogenic...

Relationship of CNS tryptaminergic processes and the action of LSD-like hallucinogens.

Pharmacology, Biochemistry, and Behavior February 1986 W R Martin, J W Sloan

Tryptamine produces pharmacologic effects in man and the chronic spinal dog which are similar to those produced by LSD, mescaline, psilocin, DMT, DOM and DOB. These effects include tachycardia, tachypnea, mydriasis, hyperreflexia, behavioral changes and in man, hallucinations. Chronic spinal dogs treated chronically with LSD became tolerant to its ability to produce mydriasis, tachycardia,...

Opioid-hallucinogen interactions.

Pharmacology, Biochemistry, and Behavior February 1986 E F Domino

Before the advent of neuroleptics, opioids such as morphine were used occasionally in the treatment of schizophrenia and other mental disorders. Recent interest in the possible therapeutic role of endogenous opioid peptides in various mental states has prompted a new look at the opioids. The present paper summarizes the research to date in the author's laboratory on opioid-hallucinogen...

Studies of the relationship between molecular structure and hallucinogenic activity.

Pharmacology, Biochemistry, and Behavior February 1986 D E Nichols

The nature of the stereochemistry and aromatic ring substituents and their importance to biological activity for phenethylamine-type hallucinogens is presented. The possibility of a hydrophobic site to bind to the 4-substituent and its likely geometry is described. A brief discussion of the structure-activity relationships for tryptamines such as psilocin and DMT is also given, with comments...

Action of hallucinogens on raphe-evoked dorsal root potentials (DRPs) in the cat.

Pharmacology, Biochemistry, and Behavior February 1, 1986 A A Larson, E G Anderson

The dorsal root potential (DRP) evoked by stimulation of the inferior central nucleus (ICN) of the cat is affected by administration of a variety of hallucinogenic agents. It has been previously shown that a single low dose of LSD is unique in that it potentiates this DRP, while injections of 5-methoxy-N,N- dimethyltryptamine (5-MeODMT), ketamine or phencyclidine (PCP) inhibit its production....

Local cerebral glucose utilisation following indoleamine- and piperazine-containing 5-hydroxytryptamine agonists.

Journal of Neurochemistry 1986 J J Grome, A M Harper 40 citations

Substances with varying structural components have been shown to have 5-hydroxytryptamine (5-HT)-like properties in the CNS. In this study, putative 5-HT agonists with indoleamine moeities--lysergic acid diethylamide (LSD) and 5-methoxy-N,N-dimethyltryptamine (5-MeODMT)--and with piperazine moieties--quipazine (Quip) and 6-chloro-2-(1-piperazinyl)pyrazine (6-CPP) were administered to rats....

Ascorbic acid antagonizes the behavioural effects of LSD in cats.

Journal of Pharmacy and Pharmacology December 1, 1985 Michael E. Trulson, Terriann Crisp, Leslie J. Henderson

Pretreatment with ascorbic acid (500 mg kg-1 i.p.) antagonized the behavioural effects of lysergic acid diethylamide (LSD) and apomorphine, but not 5-methoxy-N,N-dimethyltryptamine, in cats. The data support the hypothesis that these behavioural effects in cats are due to drug action at both 5-HT and dopamine receptors, and that the action of LSD at dopamine receptors is modulated by ascorbic...

11C-labeling of indolealkylamine alkaloids and the comparative study of their tissue distributions.

The International journal of applied radiation and isotopes December 1, 1985 T Takahashi, K Takahashi, Tatsuo Ido et al. 27 citations

Five indolealkylamines (N,N-dimethyltryptamine, N-methyltryptamine, bufotenine, O-methylbufotenine, N,N,N-trimethyltryptamine iodide) were labeled with 11C by use of 11CH3I. The labeled compounds were synthesized with a radiochemical yield of 2-50% (based on trapped 11CH3I) in 20-35 min with radiochemical purities of more than 92%. The tissue distributions of these labeled compounds were...
