The metabolism of biogenic N,N-dimethyltryptamine (DMT) starts with its enzymatic oxidation to indole-3-N,N-dimethylethaniminium cation (imDMT+) by monoamine oxidase (MAO). Following this reaction, a non-enzymatic hydrolysis occurs, yielding indole-3-acetaldehyde (IAL) and dimethylamine (DMA). In our in silico study, using a hybrid DFT method at the M06-2X/aug-cc-pVDZ level, we examined the...

Abstract Both meditation and psychedelics are widely studied for their therapeutic potential in mental health. Recent research suggests potential synergies between mindfulness practice and psychedelics, though empirical studies have primarily focused on psilocybin. This study investigates the distinct and combined effects of mindfulness practice and an ayahuasca-inspired formulation containing...

Aim: N,N-dimethyltryptamine (DMT) is a psychedelic compound under development for the treatment of major depressive disorder (MDD). This study evaluated the in vitro metabolism and clinical pharmacokinetics (PK) of DMT fumarate (SPL026) in healthy subjects. Methods: Results are from the Phase I component of an ongoing Phase I/IIa randomised, double-blind, placebo-controlled, parallel-group,...

Plant-based preparations containing the naturally occurring indole alkaloid N, N-dimethyltryptamine (DMT) are employed in ceremonial and ritualistic settings all over the globe due to their psychedelic effects. Access to pure analytical standards remains limited, posing obstacles for scientific study due to their restricted legal status in many places. Our goal in conducting this research is to...

Understanding how a simple endogenous tryptamine could occasion profound alterations in perception and self-modeling remains a key challenge for neuroscience. We advance the Birth Echo Hypothesis (BEH) : during a narrowly defined perinatal window (≈ −2 to +24 h around delivery), a convergence of hypoxic–hypercapnic stress, maximal sensory novelty, and a poly-neuromodulatory milieu...

Background: 5-Methoxy-N,N-dimethyltryptamine (5-MeO-DMT), also officially known as Mebufotenin, is a naturally occurring serotonergic psychedelic alkaloid found in the venom of the Sonoran Desert toad (Incilius alvarius) and various plant species. Areas of Uncertainty: Trace levels of 5-MeO-DMT may be produced endogenously in humans, but its physiological role remains unclear. Safety profiles...

Background: 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 (MAO) 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.Areas...

This systematic review evaluates the relationship between classical psychedelic drugs (D-Lysergic acid N,N-diethylamide, psilocybin, ayahuasca/N-N-dimethyl-tryptamine, and mescaline) and the emergence of psychotic symptoms, aiming to synthesize evidence from contemporary studies (1984-2025) regarding the risk factors, prevalence, and clinical characteristics of psychosis related to psychedelic...

BackgroundWhile psychedelic treatments for difficult-to-treat mental health conditions are advancing, participant perspectives remain under-explored. This study examined former participants’ experiences across recruitment, preparation, dosing, integration and study ending, and generated recommendations for future trials and treatment delivery.MethodsThis qualitative descriptive study, informed...

Psychedelic drugs promote rapid neuroplasticity in brain regions affected by trauma exposure, such as the prelimbic (PL) cortex and the dorsal hippocampus (DH), being investigated as potential treatments for posttraumatic stress disorder. Ayahuasca (Aya) contains N,N-dimethyltryptamine, a classic psychedelic. Our previous work showed that Aya reduces fear expression by impairing fear memory...
