Abstract The psychotropic effects of Psilocybe “magic” mushrooms are caused by the l -tryptophan-derived alkaloid psilocybin. Despite their significance, the secondary metabolome of these fungi is poorly understood in general. Our analysis of four Psilocybe species identified harmane, harmine, and a range of other l -tryptophan-derived β-carbolines as their ...
N-Benzylphenethylamines, commonly known as NBOMes, are synthetic psychedelic compounds derived from the phenethylamine class of psychedelics (2C-X compounds), which originally have been derived from the naturally occurring alkaloid mescaline. Analogously to their parent compounds and other classical psychedelics, such as psilocybin and lysergic acid diethyla...
A team of researchers has turned Escherichia coli into tiny bioreactors that can manufacture large amounts of psilocybin, the ingredient in magic mushrooms that leads to their psychoactive effects (Metab. Eng. 2019, DOI: 10.1016/j.ymben.2019.09.009). With the compound in clinical trials for treating depression and other brain diseases, says J. Andrew Jones, ...
The fungal genus Psilocybe and other genera comprise numerous mushroom species that biosynthesize psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine). It represents the prodrug to its dephosphorylated psychotropic analogue, psilocin. The colloquial term "magic mushrooms" for these fungi alludes to their hallucinogenic effects and to their use as recreational...
Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine) is the main alkaloid of the fungal genus Psilocybe, the so-called "magic mushrooms." The pharmaceutical interest in this psychotropic natural product as a future medication to treat depression and anxiety is strongly re-emerging. Here, we present an enhanced enzymatic route of psilocybin production by addin...
Abstract Psilocybin ist der psychotrope, vom Tryptamin abgeleitete Naturstoff der Psilocybe-Fruchtkörper, der so genannten “Zauberpilze”. Obwohl dessen Struktur seit 60 Jahren bekannt ist, blieb die enzymatische Grundlage ihrer Biosynthese ungeklärt. Wir charakterisierten vier Psilocybin-Biosyntheseenzyme, nämlich i) PsiD, welches zu einer neuen Klasse pilzl...
A rapid new spectrophotometric method is developed for the determination of psilocin and psilocybin using the oxidative coupling reaction with 3-methylbenzthiazolinone-2-hydrazone. The method is precise and accurate. It can be applied to the estimation of psilocin and psilocybin in forensic exhibits. Keywords: 3-methylbenzthiazolinone-2-hydrazone, psilocin, ...
The aim of the study was to develop a methodology for the determination of γ-hydroxybutyric acid (GHB), ibotenic acid (IBO) and psilocybin (PY) abuse in human saliva.
In the area of psychotropic drugs, tryptamines are known to be a broad class of classical or serotonergic hallucinogens. These drugs are capable of producing profound changes in sensory perception, mood and thought in humans and act primarily as agonists of the 5-HT2A receptor. Well-known tryptamines such as psilocybin contained in Aztec sacred mushrooms and...
Mescaline, phencyclidine (PCP) and psilocybin are potent hallucinogenic drugs strongly affecting both human and animal behavior. However, these compounds have not been previously investigated in zebrafish (Danio rerio), rapidly gaining popularity as a model in psychopharmacology research. Here, we examine the effects of mescaline, PCP and psilocybin in multi...
Psilocybe argentipes is a hallucinogenic mushroom. The present study examined the effects of P. argentipes on marble-burying behavior, which is considered an animal model of obsessive-compulsive disorder. P. argentipes significantly inhibited marble-burying behavior without affecting locomotor activity as compared with the same dose of authentic psilocybin. ...
Although psilocybin has been trained in the rat as a discriminative stimulus, little is known of the pharmacological receptors essential for stimulus control. In the present investigation rats were trained with psilocybin and tests were then conducted employing a series of other hallucinogens and presumed antagonists. An intermediate degree of antagonism of ...
An SAR study of psilocybin and psilocin derivatives reveals that 1-methylpsilocin is a selective agonist at the h5-HT(2C) receptor. The corresponding phosphate derivative, 1-methylpsilocybin, shows efficacy in an animal model for obsessive-compulsive disorder, as does 4-fluoro-N,N-dimethyltryptamine. These results suggest a new area for development of novel ...
Tryptamine produces pharmacologic effects in man and the chronic spinal dog which are similar to those produced by LSD, mescaline, psilocin, DMT, DOM and DOB. These effects include tachycardia, tachypnea, mydriasis, hyperreflexia, behavioral changes and in man, hallucinations. Chronic spinal dogs treated chronically with LSD became tolerant to its ability to...
D-lysergic acid diethylamide (LSD) displays (1) the phenylethylamine pattern present in mescaline, cyclazocine and catecholamines and (2) the 4-substituted tryptamine structure of psilocybin which is a serotonin analog. Hence (a) Naloxone--a blocker of the LSD-like side effects of cyclazocine--should (and does) block effects of LSD, and (b) cross-tolerance m...
1. LSD-25, psilocybin and JB-329 reduced the noradrenaline content of the rat hypothalamus.2. All three drugs affected the acquisition of a conditioned avoidance response, LSD-25 and psilocybin retarding and JB-329 enhancing the acquisition. With the exception of JB-329, doses affecting the acquisition of a conditioned avoidance response were lower than thos...
Psilocybin, a hallucinogen, formed a blue color with a subfraction of rat-brain mitochondria believed to contain nerve-ending particles. Color formation increased with pH, did not require oxygen, and involved a component that could not be solubilized. The effect was not shown by chemically related neuroactive compounds, such as bufotenine and serotonin, and ...
