The present study investigated interactions between the novel psychoactive tryptamines DiPT, 4-OH-DiPT, 4-OH-MET, 5-MeO-AMT, and 5-MeO-MiPT at monoamine receptors and transporters compared with the classic hallucinogens lysergic acid diethylamide (LSD), psilocin, N,N-dimethyltryptamine (DMT), and mescaline. We investigated binding affinities at human monoamine receptors and determined...

4-phosphorloxy-N,N-dimethyltryptamine (psilocybin) and methylenedioxymethamfetamine (MDMA), best known for their illegal use as psychedelic drugs, are showing promise as therapeutics in a resurgence of clinical research during the past 10 years. Psilocybin is being tested for alcoholism, smoking cessation, and in patients with advanced cancer with anxiety. MDMA is showing encouraging results as...

Ayahuasca is an Amazonian psychotropic plant tea typically obtained from two plants, Banisteriopsis caapi and Psychotria viridis. It contains the psychedelic 5-HT2A and sigma-1 agonist N,N-dimethyltryptamine (DMT) plus β-carboline alkaloids with monoamine-oxidase (MAO)-inhibiting properties. Although the psychoactive effects of ayahuasca have commonly been attributed solely to agonism at the...

Introduction New psychoactive substances (NPS) are substances that have recently appeared on the market and are not under international control. NPS use is experiencing an unprecedented increase. DiPT, 4-HO-DiPT and 4-AcO-DiPT are new psychoactive tryptamines and their effects may differ from those of other psychoactive tryptamines. Objective To explore the presence of DiPT, 4-HO-DiPT and...

The state of consciousness induced by N,N-dimethyltryptamine (DMT) is one of the most extraordinary of any naturally-occurring psychedelic substance. Users consistently report the complete replacement of normal subjective experience with a novel "alternate universe," often densely populated with a variety of strange objects and other highly complex visual content, including what appear to be...

Ayahuasca is a hallucinogenic beverage that combines the action of the 5-HT2A/2C agonist N,N-dimethyltryptamine (DMT) from Psychotria viridis with the monoamine oxidase inhibitors (MAOIs) induced by beta-carbonyls from Banisteriopsis caapi. Previous investigations have highlighted the involvement of ayahuasca with the activation of brain regions known to be involved with episodic memory,...

Vzhledem k tomu, že je v ČR ayahuasca pro svůj obsah N, N-dimethyltriptaminu dle nařízení vlády č. 463/2013 Sb., O seznamech...

New psychoactive substances (NPS) are not tested for their cytochrome P450 (CYP) inhibition potential before consumption. Therefore, this potential was explored for tryptamine-derived NPS (TDNPS) including alpha-methyl tryptamines (AMTs), dimethyl tryptamines (DMTs), diallyl tryptamines (DALTs), and diisopropyl tryptamines (DiPTs) using test substrates preferred by the Food and Drug...
