Psilocybin-producing mushrooms exhibit considerable biochemical diversity, yet the extent of variability among strains within a single species under standardized conditions remains insufficiently characterized. In this study, we quantified psilocybin, psilocin, baeocystin, norbaeocystin, aeruginascin, and norpsilocin in the fruiting bodies of 14 distinct str...
The fungivore-deterrence hypothesis, that psilocybin evolved as a chemical defence against arthropod fungivores via 5-HT receptor agonism, has become the working consensus in fungal chemical ecology, despite resting on a phylogenomic pattern of horizontal gene transfer among saprotrophs and remarkably little direct experimental evidence. Recent biochemistry ...
Psychedelics have re-emerged as promising therapeutics for neuropsychiatric disorders, including depression, anxiety, post-traumatic stress disorder, and substance use disorders. While their beneficial effects are largely attributed to serotonin 2A (5-HT2A) receptor activation, psychedelics exhibit substantial diversity in chemical structure, receptor bindin...
Limit: 5000 characters. Psilocybin, the chemical component of "magic mushrooms", has been administered with psychotherapy in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. In healthy volunteers, the psychedelic effects of psilocybin have been shown to be blocked by administration of certain medications such as r...
Psilocin is a psychedelic indole alkaloid and one of the major human metabolites of its phosphorylated precursor, psilocybin. Psilocin binds to the serotonin receptor, 5-HT2A, and dose-dependently induces hallucinogenic effects stronger than psilocybin. As a result, psilocin has been a drug of interest in the analytical toxicology community for years. In viv...
The purpose of this review is to evaluate the possible benefits of using psilocybin(C12H17N2O4P), a naturally occurring psychoactive compound found in certain species of mushrooms, in the treatment of multiple forms of mental illness and substance abuse in either monotherapy or in conjunction with traditional psychiatric medications. The compound acts as a h...
Psilocybin, the chemical component of "magic mushrooms", has been administered with psychotherapy in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. There is interest to see if similar effects may be provided in those with obsessive compulsive disorder (OCD). The purpose of this study is to evaluate the safety, f...
The Redefine Study (COMP202) is testing COMP360 to see if it may reduce post-traumatic stress disorder (PTSD) symptoms when administered alongside monitoring and support from a trained study team. COMP360 is a lab-made form of the naturally occurring chemical compound psilocybin.
Psilocybin, the chemical component of "magic mushrooms", has been administered with psychotherapy in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. In healthy volunteers, the psychedelic effects of psilocybin have been shown to be blocked by administration of serotonin (5HT)2A receptor antagonists such as risper...
Non-human models, including fish, are increasingly important for investigating how pharmacological agents such as hallucinogens influence behavior, physiology, and cellular processes. These models help to reveal underlying mechanisms and to support assessments of toxicological impact, efficacy, and safety. In this study, we used isogenic lineages of the amph...
Background: Psilocybin, a key psychoactive compound found in Psilocybe mushrooms, has gained increasing attention due to its therapeutic potential in neuropsychiatric disorders [1]. However, comparative preclinical data between isolated psilocybin and whole mushroom extracts remain scarce, particularly regarding behavioural reinforcement and peripheral toxic...
Psilocybin, chemically known as (4-phosphoryloxy-N, N-dimethyltryptamine, 4-PODMT), is derived from the psychoactive mushroom genus, Psilocybe. Of the four active metabolites, psilocin readily enters systemic circulation. The psychoactive effects of psilocin are thought to arise through partial agonist effects at the 5-HT2A receptor. Psychedelic drugs, inclu...
Psilocybin, the chemical component of "magic mushrooms", has been administered with psychological support in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. The purpose of this study is to determine the role of psilocybin monitors on the effects of psilocybin therapy in adults with treatment resistant depression....
The primary objective of this study is to investigate the safety, feasibility, and tolerability of psilocybin treatment in individuals with functional impairment due to psychiatric symptoms. The secondary objective of this study is to determine whether individuals with functional impairments due to psychiatric symptoms will experience statistically significa...
Psilocybin is an emerging investigational compound with therapeutic potential in neuropsychiatric disorders, creating a need for flexible and scalable dosage forms suitable for early clinical development. This study aimed to develop and evaluate psilocybin-loaded oral thin film (OTF) formulations as a dose-proportional platform for early-phase clinical use. ...
To support ongoing clinical trials, the major human metabolites of psilocybin were synthesized on a preparative scale, specifically psilocin-O-glucuronide and 4-hydroxyindole-3-acetic acid (4-HIAA), along with putative minor metabolites and several deuterium-labeled derivatives. Psilocybin, psilocin, psilocin-O-glucuronide, and 4-HIAA were assayed for engage...
In Canada, the use of both prescription medications and psychedelics has become increasingly prevalent. As of 2022, approximately 16.5% of Canadians-about 6.3 million individuals-were prescribed at least one antidepressant, with fluoxetine remaining one of the most commonly used options (IQVIA, 2023). Benzodiazepine use, including drugs like alprazolam, rang...
Bufotenin (also spelt as bufotenine) and its methylated derivative, 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT), are potent psychedelics that are found in many plants but also excreted by some species of toads. The compounds are regulated differently around the world, and although used in traditional medicine, 20-century prohibition culture has slowed resea...
