Abstract— In rats treated with a monoamine oxidase inhibitor, (tranylcypromine), L‐ tryptophan produces a stereotyped syndrome of hyperactivity and hyperpyrexia due to an increased rate of brain serotonin (5‐hydroxytryptamine) synthesis. Pretreatment of rats with intraperitoneal injections of cycloheximide, acetoxycycloheximide, emetine and dehydroemetine and of mice with puromycin inhibited...
1. The hyperactivity and hyperpyrexia produced by L-tryptophan in rats treated with a monoamine oxidase inhibitor was inhibited by chlorpromazine.2. Chlorpromazine did not inhibit the increased rate of synthesis of brain 5-hydroxytryptamine (5-HT) produced by tryptophan loading.3. Hyperactivity and hyperpyrexia were also produced by 5-methoxy-N,N-dimethyltryptamine (5-MeODMT) in rats....
Thin titanium films have been bombarded with low energy (350 eV) deuterium ions at high current density (0.2-0.4 mA.cm2) to investigate the reported occurrence of nuclear reactions at ambient temperatures in deuterium charged metals. A silicon charged particle detector was used to search for charged particles produced by such reactions. Evidence is reported for the detection of hydrogen...
The effect of 5-methoxy-N:N-dimethyltryptamine on the conditioned avoidance response of trained rats was compared quantitatively, using a shuttle-box, with that of several substituted tryptamines and LSD-25. 5-Methoxy-N:N-dimethyltryptamine, at a dose level of 19 µm/kg, had a pronounced effect on the conditioned avoidance response, much more pronounced than that due to the known psychotomimetic...

The so-called experimental psychoses have been in the focus of increased interest recently, as a result of the discovery of new hallucinogenic or psychotic agents and of the fact that the problems can be approached more closely even in the borderline fields of pathopsychological research (biochemistry, electrophysiology, etc.) owing to advance in technique. Thus, it appears that Kraepelin's...
N,N-dimethyltryptamine (DMT) is a naturally occurring serotonergic psychedelic found in natural plants around the globe. As the main psychoactive component in ayahuasca, which also contains monoamine oxidase inhibitors, DMT has been consumed as plant-based brew by indigenous peoples for centuries. Further research is required to delineate the therapeutic utility of DMT. Although previous...

Ayahuasca, used religiously for centuries by Amazonian Indigenous peoples and increasingly studied for its therapeutic potential, owes its psychoactivity to two plants: Psychotria viridis supplies N,N-dimethyltryptamine (DMT), whereas Banisteriopsis caapi supplies beta-carbolines that render DMT orally active. Here we show that the two plants have distinct genome histories: P. viridis is...

Study molecular of interaction between N,N-dimethyltryptamine analogs (DMT) with 5-HT1A and 5-HT1B receptors. Likewise, complexes mechanisms that related the interaction with these receptors involved in alterations such as depression, post-traumatic stress disorders and anxiety. Therefore, have been evaluated the activity of DMT analogs by docking molecular studies in the determination of the...

N,N-dimethyltryptamine (DMT) is an endogenous psychedelic tryptamine characterizedby a short duration of action due to its rapid metabolic degradation mediated by monoamineoxidase A (MAO-A), a flavoprotein that utilizes flavin adenine dinucleotide (FAD) as a redoxcofactor. When ingested as part of ayahuasca, a traditional Amazonian decoction containingPsychotria viridis (a source of DMT) and...
