Certain characteristic fragmentations of tryptamines (indoleethylamine) and phenethylamines are described. Based on the GC-EI/MS, LC-ESI/MS and MALDI/TOFMS, the mass fragmentations of 13 standard compounds, including alpha-methyltryptamine (AMT), N,N-dimethyltryptamine (DMT), 5-methoxy-alpha-methyltryptamine (5-MeO-AMT), N,N-diethyltryptamine (DET), N,N-dipropyltryptamine (DPT),...
Un échantillon de la boisson ayahuasca contenant les alcaloïdes harmalol, harmol, harmane et N,N-diméthyltryptamine a été évalué dans les tests de nage forcée et d'open-field. Dans le test de nage forcée, les doses ont diminué le temps d'immobilité d'une manière inversement proportionnelle à la dose. Des doses de 2,5 mg/kg et de 10 mg/kg d'ayahuasca ont diminué aussi l'activité locomotrice et...
ObjectivesAyahuasca is a traditional South American psychoactive beverage and the central sacrament of Brazilian-based religious groups, with followers in Europe and the United States. The tea contains the psychedelic indole N,N-dimethyltryptamine (DMT) and beta-carboline alkaloids with monoamine oxidase-inhibiting properties that render DMT orally active. DMT interacts with serotonergic...
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 psilocybin was observed following...
Casey Hardison was arrested in spring 2004 for the production of psychedelictype drugs ie. LSD, 2C‐B and DMT. In the three years since, not one person from ‘authority’ had bothered to ask him what motivated him to synthesise psychedelic drugs. It was as if the a priori assumption that ‘all illegal drugs are bad’ had provided the answer. Hence, the Judge asserted that Hardison did it for ‘that...
A new chlorotryptamine alkaloid, N-chloromethyl-N,N-dimethyltryptamine, was isolated from a methanol extract of the Chinese shrub Acacia confusa Merr., together with its known hallucinogenic analogues, N-methyltryptamine, N,N-dimethyltryptamine and N,N-dimethyltryptamine-N-oxide. The new compound was an artefact of the isolation conditions. The complete (1)H and (13)C NMR assignments for these...
We developed a reproducible, simple, and small-scale method for determining the re-uptake and release of monoamines (dopamine, serotonin (5-HT) and norepinephrine) using rat brain synaptosomes. These assays were then applied to study the effects of different kinds of non-medically used psychoactive drugs on monoamine re-uptake and release. The phenethylamine derivatives, 4-fluoroamphetamine,...
0 Centro Epirita Beneficente Uniao do Vegetal (UDV) is a Christian Spiritist sect based in Brazil, with an American branch of approximately 130 individuals. Founded in Brazil in 1961, the UDV church blends aspects of Christian theology with traditional Brazilian indigenous religious beliefs.' In 1993, the UDV officially established a United States branch headquartered in Santa Fe, New Mexico. 2...
We constructed a reproducible, simple, and small-scale determination method of the psychoactive drugs that acted directly on the monoamine receptor by measuring the activation of [(35)S]guanosine-5'-O-(3-thio)-triphosphate binding to guanine nucleotide-binding proteins (G proteins). This method can simultaneously measure the effects of three monoamines, namely dopamine (DA), serotonin (5-HT),...
The constituents of seven mushrooms sold as Amanita muscaria or Amanita pantherina (five A. muscaria and two A. pantherina) and four "extracts purported to contain A. muscaria" products that are currently circulated in Japan were determined. All mushroom samples were identified as A. muscaria or A. pantherina by macroscopic and microscopic observation. The dissociative constituents, ibotenic...
