ABSTRACT Three novel 14 C‐labelled isotopologues of the psychoactive agents psilocin, psilocybin and 5‐methoxy‐ N , N ‐dimethyltryptamine (5‐MeO‐DMT) were synthesised, all labelled at the 2‐position of the indole. The syntheses involved incorporating the 3‐dimethylaminoethyl substituent common to all three substances onto a 4‐ or 5‐substituted indole intermediate via successive treatments with...

Psychoactive substances are compounds that can influence perception, consciousness, cognition, and emotions. The psychoactive substances caffeine, nicotine, cannabis, and psilocybin all originate from natural sources and can be used without complex processing or synthesis. Their natural availability has contributed to a long-standing history of human use and cultural significance. Caffeine and...

Background: Persisting symptoms after concussion is a complex syndrome warranting exploration into further treatment options. Emerging research highlights the potential of classic psychedelics, such as psilocybin, in managing neuropsychiatric conditions and promoting neuroprotection. Case Report: A case is presented of a 22-year-old male intercollegiate athlete who sustained a concussion and...

Acyloxymethyl (ACOM) derivatives of tryptamines such as the psychedelic drug psilocin and the anti-migraine drug sumatriptan bear potential as prodrugs. Previous synthetic approaches suffer from insufficient chemoselectivity between the desired functionalization of the phenolic (psilocin) or sulfonamide (sumatriptan) groups versus other reactive groups in the parent drugs. We report a novel...

The Psilocybe genus is known for producing tryptamine alkaloids, specifically the compounds psilocybin and psilocin, which have shown antidepressant and anxiolytic potential. The presence of these alkaloids makes Psilocybe mushrooms promising sources of molecules with potential applications in the treatment of mental disorders. To explore this, a bibliographic study was conducted with the aim...

Background: Psilocybin-assisted psychotherapy (PAP) is a promising treatment for various psychiatric disorders. However, the exact biological and psychological mechanisms of action of PAP remain to be determined. Examining predictors of PAP outcomes may help identify necessary processes for positive treatment outcomes. Mystical experiences are considered a key aspect of the subjective effects...

Obsessive-compulsive disorder (OCD) is a common and disabling condition. A large proportion of patients fail to respond to first-line treatment with serotonin reuptake inhibitors either selective serotonin reuptake inhibitors (SSRIs) or clomipramine. Preliminary evidence suggests psilocybin, a serotonin receptor agonist, might be efficacious. We conducted a pharmacological challenge study to...

Abstract Background : Military veterans are at risk of various mental health conditions, with profound implications for post‐deployment quality of life. Current treatment options encounter high dropout rates and non‐responsiveness, and overlook the importance of community building in veterans’ holistic recovery. Preliminary research suggests psychedelics offer therapeutic benefits for...

Psilocybe cubensis is a widely used psilocybin-containing mushroom with well-documented acute psychoactive effects. We report a case of prolonged perceptual disturbances and flashbacks occurring weeks after ingestion, requiring psychopharmacological intervention. This case illustrates the potential for persistent neuropsychiatric symptoms following psilocybin intoxication and highlights the...

This systematic review and meta-analysis evaluates (1) the effectiveness of psychedelic-assisted therapy (PAT) using psilocybin and ketamine for psychosocial symptoms in adults with cancer, (2) contextualizes findings with non-randomized and exploratory studies of other psychedelics, and (3) examines the role of therapeutic frameworks in shaping outcomes. We searched PubMed, Cochrane Library,...

Parkinson’s Disease (PD) is a progressive neurodegenerative disorder marked by motor symptoms due to dopaminergic degeneration and non-motor symptoms such as depression, anxiety, and cognitive impairment, which significantly affect patients' quality of life. Traditional dopaminergic therapies address motor symptoms but offer limited efficacy for neuropsychiatric manifestations. Psilocybin, a...

Psychedelics are increasingly used in the general population, yet they are associated with increased risk of psychosis in a minority of users that can experience psychedelic-induced psychosis (<1 % in controlled trial settings). In contrast, the evidence regarding the treatment of psychedelics-induced psychosis remains to date scarce. We conducted a PRISMA 2020-compliant systematic review...

Psilocybin, a serotonergic psychedelic, has demonstrated therapeutic potential in neuropsychiatric disorders. While its neuroplastic and immunomodulatory effects are recognized, the underlying mechanisms remain unclear. This study investigates how psilocybin and its active metabolite, psilocin, influence microglial inflammatory responses and neurotrophic factor expression through serotonergic...

Abstract Serotonergic psychedelics alter self-boundaries and can induce out-of-body experiences (OBEs)—the sense of being located outside one’s physical body. While OBEs also occur in clinical conditions and can be experimentally induced, their neural basis under psychedelics remains underexplored. In an open-label, baseline-controlled MRI study of 62 healthy adults administered psilocybin, we...

The coronavirus variant (causing the COVID-19 disease) that led to a pandemic sent global shockwaves, resulting in long-term effects on physical, mental, and social well-being and impacting both individuals and communities. With the pandemic's notable impact on mental health, one such potential treatment discussed in recent literature is psilocybin. Psilocybin is a naturally occurring prodrug...

Patients with Major Depressive Disorder (MDD) have more dysfunctional attitudes than healthy individuals and these pessimistic biases are correlated with depression severity. Psilocybin has demonstrated sustained remission in depression. Secondary analysis of a two-arm randomized controlled trial assessing the effect of psilocybin therapy versus escitalopram on 'maladaptive' cognitive biases...

Background: Alcohol Use Disorder (AUD) is a chronic pathological condition with significant burdens throughout the world. Despite the effectiveness of the current pharmacological treatments, the ongoing issues with AUD and the high relapse rates necessitate the exploration of innovative therapies, including the use of psychedelic drugs, which have shown promising initial results. The purpose of...
