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...
Psilocin (4-hydroxy-N, N-dimethyltryptamine) is a substituted tryptamine alkaloid and a nonselective serotonergic agonist acting predominantly at 5-HT2A/C receptors, with substantial binding to 5-HT1A and 5-HT2B receptors. Microdosing is the practice of taking a very small, sub-perceptual dose, typically 5% to 10% of a full recreational dose, to improve mood...
Background: Psilocybe cubensis mushrooms contain the tryptamines psilocybin and psilocin, which are recognized for their therapeutic potential in mental health [1]. Additionally, due to their psychedelic effects, these mushrooms are also used for religious and recreational purposes. The increasing use of these tryptamines and other psychoactive substances ha...
BackgroundPsychedelics such as lysergic acid diethylamide (LSD) and psilocybin have shown a beneficial effect on substance use disorder (SUD) symptoms. In this systematic review, we aimed to assess the efficacy and safety of psychoactive tryptamines in patients with an SUD or non-substance-related disorder (i.e., gambling disorder) in order to provide a comp...
As psychedelic-assisted psychotherapy gains momentum, clinical investigation of next-generation psychedelics may lead to novel compounds tailored for specific populations. 2,5-dimethoxy-4-bromophenethylamine (2C-B) is a psychedelic phenethylamine reported to produce less dysphoria and subjective impairment than the psychedelic tryptamine psilocybin. Despite ...
Psilocybin is a psychoactive tryptamine produced by a phylogenetically discontinuous yet ecologically diverse subset of fungi. Despite decades of chemical, pharmacological, and ethnobiological research, the evolutionary forces driving the emergence and persistence of this compound remain insufficiently explained. Recent hypotheses proposing that psilocybin e...
Novel psychoactive substances (NPS) remain an ongoing challenge for public health, forensic laboratories, and regulatory agencies, especially when they are chemically related to controlled tryptamines but are marketed as legal alternatives. In the United States, the Federal Analogue Act (FAA) was intended to restrict such substances; however, regulatory loop...
BACKGROUND: The claustrum, a subcortical structure densely expressing 5-hydroxytryptamine 2 A (5-HT2A) receptors, has been implicated in sensory integration, emotional regulation, salience, and attention. Despite its hypothesized involvement in the effects of serotonergic psychedelics, the neurochemical impact of these substances on claustral neurotransmissi...
Psilocybin, a tryptamine-derived alkaloid from Psilocybe mushrooms, has emerged as a high-value biopharmaceutical candidate due to its promising applications in mental health. While clinical studies highlight its rapid and sustained antidepressant effects, current challenges lie in achieving scalable, reproducible, and cost-effective production to meet growi...
ABSTRACT Psilocybin, an indole alkaloid of psychedelic mushrooms, has the potential to sustainably improve the treatment of several psychiatric diseases. So far, the psilocybin demand for clinical trials has been met by chemical synthesis. In this study, we pursued the biotechnological approach to develop a psilocybin production process utilizing an overprod...
Psilocybin, a naturally occurring tryptamine alkaloid found in over 200 species of fungi, has emerged as a focal point in the modern revival of psychedelic science. Once relegated to the margins of psychopharmacology due to its association with counterculture and strict legal restrictions, psilocybin is now undergoing a scientific renaissance. This transform...
The overall objective of this study is to assess the feasibility, safety and preliminary efficacy of psilocybin-assisted therapy to alleviate opioid-refractory pain in patients with advanced-cancer. The name of the study intervention used in this research study is: Psilocybin (a tryptamine derivative) This study is a phase 2 open label, single center, concur...
Psychedelic mushrooms of the Psilocybe genus contain the psychoactive tryptamines psilocybin and psilocin, compounds currently under clinical investigation for the treatment of depression and other psychiatric conditions. However, the accurate quantification of these alkaloids in fungal matrices remains analytically challenging. Here, we report an optimized ...

BACKGROUND: The consumption of dried fruiting bodies of Psilocybe cubensis can be traced over centuries, guided by Mesoamerican curanderas, Western medical practitioners, and fungal enthusiasts, all seeking mental wellbeing. There is a notable resurgence in interest both in the fungal biomass and psilocybin, the psychoactive tryptamine, despite the global re...
The classical psychedelics (+)-lysergic acid diethylamide (LSD), psilocybin, and mescaline exert their psychedelic effects via activation of the 5-HT2A serotonin receptor (5-HT2AR). Recent clinical studies have suggested that classical psychedelics may additionally have therapeutic potential for many neuropsychiatric conditions including depression, anxiety,...
ABSTRACT 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 gro...
