Receptor Binding Profiles for Tryptamine Psychedelics and Effects of 4-Propionoxy-N,N-dimethyltryptamine in Mice

ACS Pharmacology & Translational Science  – March 10, 2023

Summary

Beyond the expected 5-HT2A receptor, new tryptamine psychedelics influence behavior through complex pharmacology, targeting multiple serotonin receptors, including 5-HT1A. Variations in chemical synthesis and stereochemistry, specifically N,N-dialkyl substitutions, altered binding profiles across alpha, dopamine, and histamine receptors. One analogue, 4-PrO-DMT, induced psychedelic-like head twitches in mice at 0.3-3 mg/kg, but also 5-HT1A-mediated hypothermia and reduced locomotion at 3-30 mg/kg. This suggests 5-HT1A activity can attenuate 5-HT2A-mediated effects, crucial for understanding neurotransmitter receptor influence on behavior in drug studies.

Seasonal Effect on the Chemical Composition of Mimosa tenuiflora (Willd.) Poir Stem Bark from the Semi‐Arid Region of Pernambuco, Brazil

Chemistry & Biodiversity  – September 23, 2025

Summary

Mimosa tenuiflora, or "Jurema-preta," reveals significant seasonal variation in its chemical profile, impacting its medicinal applications. Over a 24-month period, plant samples collected bimonthly in Petrolina, Brazil, demonstrated that phenolic compounds, particularly flavonoids, are linked to water stress and temperature changes. Interestingly, N,N-dimethyltryptamine (DMT) production negatively correlated with radiation and temperature but not precipitation. The study involved 24 collections and highlighted the need for seasonally informed collection strategies to optimize the pharmacological use of this valuable species.

N, N-Dimethyltryptamine and harmine formulation shifts metastable topography sequences in the cortex

OpenAlex  – December 09, 2025

Summary

Psychedelics like DMT and harmine significantly accelerate brain dynamics, as evidenced by a study involving 25 participants. The use of microstate analysis revealed that while the duration of neural states decreased, the frequency of transitions increased, indicating heightened activity. Notably, the sequence of states became less random, with a 30% rise in accessibility to certain states (M3 and M5) while M2 was deprioritized. This suggests that psychedelics promote a structured reorganization of neural activity, enhancing the brain's capacity for diverse patterns and metastability.

Abstract

Abstract Classic serotonergic psychedelics are potent modulators of conscious awareness, yet the principles governing their effects on the temporal...

The Neurophysiology of Enlightenment: Measured EEG Markers at 43 Hz and t=41 s

Zenodo (CERN European Organization for Nuclear Research)  – December 23, 2025

Summary

Enlightenment has been identified as a measurable brain state, with findings showing significant neurophysiological markers at precisely 41 seconds post-stimulation. In a study involving breakthrough subjects under the influence of 5-MeO-DMT and during sustained meditation, EEG data revealed a striking 43 Hz coherence featuring DMN deactivation and gamma synchrony. The analysis included 50 participants, demonstrating a convergence of key metrics like complexity drop and persistence loss, suggesting consciousness may act as a physical field relevant to quantum mind theories.

Psychedelics and Suicide-Related Outcomes: A Systematic Review

Journal of Clinical Medicine  – February 20, 2025

Summary

Suicide accounts for 1.4% of global deaths, urging new Medicine. Psilocybin and MDMA show promise in suicide prevention, rapidly reducing suicidal ideation. A systematic review of PsycINFO and MEDLINE found four randomized controlled trials with psilocybin (three studies) and MDMA (one study) reducing suicidal ideation (effect sizes 0.52–1.25). Non-randomized studies reported psilocybin reducing ideation (OR 0.40–0.75). However, LSD, another hallucinogen, increased suicidal ideation (OR 1.15–2.08). Complex neurotransmitter receptor influence means psychedelics' impact on suicidal ideation remains inconclusive for Psychiatry.
