Psilocybin and Ibogaine in Cocaine‐Seeking: Extinction Enhancement Without Relapse Prevention

Addiction Biology March 1, 2026 Isis Koutrouli, Vojtěch Brejtr, Marek Schwendt et al.

Psychedelics have emerged as potential therapeutics for substance use disorders, yet preclinical data validating their efficacy remain limited. Here, we investigated the effects of a clinically inspired dose-escalation protocol of psilocybin and ibogaine on extinction and cue-induced reinstatement in Wistar male rats following intravenous cocaine self-administration (IVSA). Rats were trained on...

Behavioural and pharmacological evaluation of the psilocybin analogue baeocystin in Wistar rats.

Progress in Neuro-Psychopharmacology and Biological Psychiatry July 5, 2025 Hynek Danda, Kristýna Mazochová, Klára Šíchová et al. 1 citation

Baeocystin is a naturally occurring tryptamine-based compound found in various psychoactive mushrooms, including in several species of Psilocybe genus. Due to its structural similarity to psilocybin, which has shown a therapeutic potential in treatment of psychiatric disorders, there is a growing interest in investigating whether baeocystin exhibits comparable effects. This study investigated...

Effects of serotonergic psychedelics on synaptogenesis and immediate early genes expression - comparison with ketamine, fluoxetine and lithium.

Journal of Psychopharmacology May 28, 2025 Yana Vella, Kateřina Syrová, Aneta Petrušková et al. 1 citation

Recent evidence suggests that psychedelics can induce rapid and long-lasting antidepressant effects. The generally acknowledged explanation for these traits is the phenomenon of neuroplasticity, although the exact underlying molecular mechanisms remain unclear. This study investigates the effects of psilocin, lysergic acid diethylamide (LSD) and N,N-dimethyltryptamine (DMT) on synaptogenesis...

DETERMINATION OF TRYPTAMINE ALKALOIDS AND THEIR STABILITY IN PSYCHOTROPIC MUSHROOMS

The International Journal of Neuropsychopharmacology February 1, 2025 Martin Kuchař, Klara Gotwaldova, Jan Borovička et al. 1 citation

Abstract Synthetic psilocybin (PSB), but also the PSB-containing mushrooms are used for psychedelic therapy and microdosing. It is necessary to know alkaloids variability and stability in wild-grown mushrooms. Concentrations of other psychotropic (or potentially psychotropic) tryptamines such as psilocin (PS), baeocystin (BA), norbaeocystin (NB), and aeruginascin (AE) are also relevant. This...

Stability of psilocybin and its four analogs in the biomass of the psychotropic mushroom Psilocybe cubensis

Drug Testing and Analysis October 29, 2020 Klára Gotvaldová, Kateřina Hájková, Jan Borovička et al. 69 citations

Abstract Psilocybin, psilocin, baeocystin, norbaeocystin, and aeruginascin are tryptamines structurally similar to the neurotransmitter serotonin. Psilocybin and its pharmacologically active metabolite psilocin in particular are known for their psychoactive effects. These substances typically occur in most species of the genus Psilocybe (Fungi, Strophariaceae). Even the sclerotia of some of...

A single inhalation of vapor from dried toad secretion containing 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) in a naturalistic setting is related to sustained enhancement of satisfaction with life, mindfulness-related capacities, and a decrement of psychopathological symptoms.

Psychopharmacology April 13, 2019 Malin V. Uthaug, R. Lancelotta, Kim van Oorsouw et al. 198 citations

Background: 5-methoxy-N,N-dimethyltryptamine (hereinafter referred to as 5-MeO-DMT) is a psychedelic substance found in the secretion from the parotoid glands of the Bufo alvarius toad. Inhalation of vapor from toad secretion containing 5-MeO-DMT has become popular in naturalistic settings as a treatment of mental health problems or as a means for spiritual exploration. However, knowledge of...

Synthesis of methoxetamine, its metabolites and deuterium labelled analog as analytical standards and their HPLC and chiral capillary electrophoresis separation

RSC Advances 2017 Bronislav Jurásek, Michal Himl, Radek Jurok et al. 13 citations

Methoxetamine, a designer drug marketed as a replacement for the dissociative anaesthetic ketamine, has been associated with significant numbers of hospital related intoxications and deaths in Europe.
