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...

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...

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...

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...

N-Benzylphenethylamines are novel psychedelic substances increasingly used for research, diagnostic, or recreational purposes. To date, only a few metabolism studies have been conducted for N-2-methoxybenzylated compounds (NBOMes). Thus, the available 2,5-dimethoxy-4-(2-((2-methoxybenzyl)amino)ethyl)benzonitrile (25CN-NBOMe) metabolism data are limited. Herein, we investigated the metabolic...

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.

Tryptamines are a group of hallucinogenic drugs whose detection in body fluids could be simplified by immunochemical assay kits. Antibodies for these assays are obtained by the immunization of laboratory animals with conjugates of a hapten similar to the target analyte and a suitable protein. Therefore we synthesized novel haptens derived from tryptamine-based drugs, with N,N-dimethyltryptamine...
