Serotonergic psychedelics, such as N,N-dimethyltryptamine (DMT), have shown therapeutic potential in various psychiatric disorders. However, DMT demonstrates pharmacokinetic (PK) variability and a short half-life. This exploratory study investigated the PK, pharmacodynamic (PD), and safety profile of CYB004, a deuterated DMT analogue, following intravenous administration in healthy volunteers....
ABSTRACT Psychedelic compounds exhibit diverse pharmacological and clinical effects, underscoring the need for further research and the development of clear guidelines to support their safe and effective clinical use. Growing interest in psychedelics has also increased attention toward the relationship between nutrition, dietary habits, and psychiatric disorders. This narrative review presents...
Abstract Background Serotonergic psychedelics show promise for treating psychiatric disorders, with symptom improvements lasting for weeks after a single dose. Clarifying the neural basis of these effects would benefit from an identification of empirical biomarkers of such lasting shifts in brain function. Resting state EEG offers a rapid (<5 minute), low-cost window into functional brain...
Abstract N, N-dimethyltryptamine (DMT) and 5-methoxy-N, N-dimethyltryptamine (5-MeO-DMT) are structurally related tryptamine psychedelics with emerging therapeutic potential, yet their comparative acute pharmacology and longer-term neuroplastic effects remain incompletely defined. Here we show that DMT produces a bell-shaped dose–response curve in the mouse head-twitch response (HTR) assay,...
Abstract Adult dentate gyrus neurogenesis and cell proliferation are regulated by multiple physiological inputs, including experience-dependent signals that have been linked to the DNA glycosylase NEIL3. Whether NEIL3 also gates psychedelic-induced proliferation is unknown. Here we tested the effect of a single dose of 5-methoxy-N, N-dimethyltryptamine (5-MeO-DMT), a serotonergic agonist with...

Recent patent applications disclose selective 5-HT2A receptor activators, precision aerosol delivery technologies for psychedelic compounds,...
The serotonergic psychedelic N,N-dimethyltryptamine (DMT) produces rapid antidepressant effects in preclinical and early clinical studies. Therapeutic benefits have been linked to sustained neural plasticity, including adult neurogenesis in rodents. Whether brief DMT exposure engages proliferative responses in human neural stem cells (NSCs) remains unresolved. Using human iPSC-derived NSCs, we...
N,N-dimethyltryptamine (DMT) is a bioactive indole alkaloid that could greatly benefit from scalable, fermentation-based production for research and pharmaceutical applications. In this study, we reconstructed a two-step bacterial pathway converting L-tryptophan to DMT via tryptamine. This involved combining a pyridoxal 5'-phosphate (PLP)-dependent tryptophan decarboxylase from the bacterium...

N,N-dimethyltryptamine (DMT) is an naturally occurring indoleamine with hallucinogenic and antidepressant effects in humans. Here, we compared the effects of DMT and S-ketamine, a fast-acting antidepressant, in helpless mice. To induce helplessness, male single and group-housed mice were exposed to inescapable footshock stress; only helpless animals were subsequently treated with S-ketamine 10...
The brain’s ability to rewire itself, neuroplasticity, declines dramatically with age. Children learn faster; adults get stuck in patterns; older adults struggle to adapt. The reasons for this decline remain unclear. In a companion paper (Solis, 2026a), I critically evaluated the broad hypothesis that N,N-dimethyltryptamine (DMT) has endogenous physiological functions. The evidence was found to...
