Molecular determinants for binding of methylenedioxytryptamines at 5-HT/LSD receptors

International Journal of Quantum Chemistry  – March 05, 1981

Summary

Affinity for the serotonin (5-HT) receptor can be predicted based on molecular rearrangements, according to findings from a study involving 50 tryptamine derivatives. The research identified that when specific methylenedioxy substituents were placed at the 5.6 or 4.5 positions, these molecules exhibited distinct reactivity patterns. Preliminary data showed that the binding affinity of these derivatives to 5-HT/LSD receptors aligns with theoretical predictions, revealing a strong link between intramolecular forces and drug recognition, crucial for understanding psychedelics' biochemical interactions.

Abstract

In investigations of the molecular determinants for the recognition of drugs by a serotonin (5-HT) receptor in the brain, the commonality in the re...

Tritiated LSD Binding in Frontal Cortex in Schizophrenia

Archives of General Psychiatry  – March 01, 1981

Summary

Binding of tritiated LSD to the frontal cortex is crucial for understanding schizophrenia, with previous reports suggesting a reduced number of serotonin receptors. However, analysis of 13 schizophrenia patients revealed no decrease in binding compared to eight control brains. Notably, five patients likely free from neuroleptics showed significantly increased LSD binding. This suggests that lingering neuroleptic medications may skew results. The findings highlight the need for larger studies to confirm these insights into the relationship between psychedelics, brain chemistry, and mental health.

Abstract

It has been reported that the binding of tritiated LSD (at 2 or 4 nm) to frontal cortex is reduced in schizophrenia, a finding that has been interp...

Mushrooms and Madness: Hallucinogenic Mushrooms and Some Psychopharmacological Implications

The Canadian Journal of Psychiatry  – November 01, 1980

Summary

Surprisingly, despite extensive historical and neurochemical understanding of hallucinogenic fungi, a significant blind spot persists in Psychedelics and Drug Studies. While psilocybin is a prominent psychoactive substance, only an estimated 7% of research in Psychology and Psychiatry specifically explores how psilocybin-related alkaloids, formed via complex chemical synthesis and with distinct pharmacology, might influence psychotic illness. Investigating the neurochemical pathways of these potent hallucinogens, particularly indole compounds like baeocystin, is crucial for advancing our understanding of these alkaloids.

THE INTEGRITY OF THE SOCIAL HIERARCHY IN MICE FOLLOWING ADMINISTRATION OF PSYCHOTROPIC DRUGS

British Journal of Pharmacology  – November 01, 1980

Summary

Mice in small groups establish a rigid social hierarchy that resists change, even when exposed to psychotropic drugs like diazepam, droperidol, and mescaline. In a study involving groups of three mice, these drugs altered aggression levels but did not shift social positions. However, chronic use could lead to a reversal of hierarchy under competitive conditions. The degree of hierarchy inversion depended on the initial social structure, suggesting that drug-induced changes in aggression may reflect broader neuroendocrine regulation and behavior dynamics.

Sensory and associative effects of LSD in classical conditioning of rabbit (Oryctolagus cuniculus) nictitating membrane response.

Journal of Comparative and Physiological Psychology  – January 01, 1980

Summary

LSD significantly enhances the acquisition of conditioned responses in rabbits, with a notable increase in conditioned response frequency observed across various stimulus intensities. In a sample of 30 rabbits, LSD improved conditioned responses without affecting unconditioned response amplitude or psychophysical functions related to unconditioned stimulus intensity. Specifically, LSD lowered the threshold for conditioned stimuli, indicating enhanced sensory processing. This suggests that LSD facilitates associative learning by improving both learning and performance mechanisms, highlighting its potential influence on memory and neural mechanisms.

Dissociations Between the Effects of LSD on Behavior and Raphe Unit Activity in Freely Moving Cats

Science  – August 03, 1979

Summary

Low doses of LSD can trigger significant behavioral changes, even with minimal impact on serotonergic raphe neuron activity. In a study involving freely moving cats, only a 10% decrease in raphe unit activity was observed alongside notable behavioral effects. Interestingly, these behavioral changes persisted beyond the initial depression of neuron activity, suggesting a complex relationship between serotonin levels and behavior. Additionally, raphe neurons demonstrated consistent responsiveness to LSD during tolerance, indicating that the effects of psychedelics may not solely rely on immediate serotonergic activity.

Abstract

The hypothesis that the action of hallucinogenic drugs is mediated by a depression of the activity of brain serotonergic (raphe) neurons was tested...

BACKWARD WALKING AND CIRCLING: BEHAVIOURAL RESPONSES INDUCED BY DRUG TREATMENTS WHICH CAUSE SIMULTANEOUS RELEASE OF CATECHOLAMINES AND 5‐HYDROXYTRYPTAMINE

British Journal of Pharmacology  – August 01, 1979

Summary

Simultaneous release of Dopamine and Serotonin drives unusual motor behaviors like backward walking and circling in rats. Administering 15mg/kg Amphetamine, which primarily releases catecholamines, or serotonin-releasing Fenfluramine or P-Chloroamphetamine, induced these actions. Crucially, combining lower doses—5mg/kg Dextroamphetamine with 2-5mg/kg P-Chloroamphetamine or 5mg/kg Fenfluramine—also produced them. Interestingly, Fenfluramine reduced characteristic dopamine-dependent behaviors like licking. These insights in Pharmacology and Medicine are vital for understanding hallucinogen effects.
