Neurotoxicological profile of the hallucinogenic compound 25I-NBOMe.

Scientific Reports February 21, 2022 Monika Herian, Adam Wojtas, Marzena Maćkowiak et al. 15 citations

4-Iodo-2,5-dimethoxy-N-(2-methoxybenzyl)phenethylamine (25I-NBOMe) is a new psychoactive substance with strong hallucinogenic properties. Our previous data reported increased release of dopamine, serotonin, and glutamate after acute injections and a tolerance development in the neurotransmitters release and rats' behavior after chronic treatment with 25I-NBOMe. The recreational use of 25I-NBOMe...

N,N‐dimethyltryptamine and Amazonian ayahuasca plant medicine

Human Psychopharmacology: Clinical and Experimental February 17, 2022 Edward James, Joachim Keppler, Ben Sessa et al. 41 citations

Abstract Objective Reports have indicated possible uses of ayahuasca for the treatment of conditions including depression, addictions, post‐traumatic stress disorder, anxiety and specific psychoneuroendocrine immune system pathologies. The article assesses potential ayahuasca and N,N‐dimethyltryptamine (DMT) integration with contemporary healthcare. The review also seeks to provide a summary of...

Neurovascular Uncoupling: Multimodal Imaging Delineates the Acute Effects of MDMA

bioRxiv Preprint Server February 14, 2022 Tudor M. Ionescu, Mario Amend, Tadashi Watabe et al. 1 citation preprint

Psychedelic compounds have attracted increasing interest in recent years due to their therapeutic potential for psychiatric disorders. Methylenedioxymethamphetamine (MDMA) is currently being investigated in clinical trials to treat post-traumatic stress disorder. To understand the acute effects of psychedelic drugs in vivo, functional MR imaging (fMRI) has been widely used in recent years....

The clinical pharmacology and potential therapeutic applications of 5‐methoxy‐N,N‐dimethyltryptamine (5‐MeO‐DMT)

Journal of Neurochemistry February 12, 2022 Johannes T. Reckweg, Malin V. Uthaug, Attila Szabo et al. 108 citations

Abstract 5‐methoxy‐N,N‐dimethyltryptamine (5‐MeO‐DMT) is a naturally occurring tryptamine that primarily acts as an agonist at the 5‐HT1A and 5‐HT2A receptors, whereby affinity for the 5‐HT1A subtype is highest. Subjective effects following 5‐MeO‐DMT administration include distortions in auditory and time perception, amplification of emotional states, and feelings of ego dissolution that...

Receptor Interaction Profiles of 4-Alkoxy-3,5-Dimethoxy-Phenethylamines (Mescaline Derivatives) and Related Amphetamines

Frontiers in Pharmacology February 9, 2022 Karolina E. Kolaczynska, Dino Luethi, Dino Luethi et al. 16 citations

3,4,5-Trimethoxyphenethylamine (mescaline) is a psychedelic alkaloid found in peyote cactus. Related 4-alkoxy-3,5-dimethoxy-substituted phenethylamines (scalines) and amphetamines (3C-scalines) are reported to induce similarly potent psychedelic effects and are therefore potential novel therapeutics for psychedelic-assisted therapy. Herein, several pharmacologically uninvestigated scalines and...

Hallucinogen chemistry guides antidepressant drug discovery

C&EN Global Enterprise February 7, 2022 Bethany Halford

Scientists have long sought the secrets of the 5-HT 2A serotonin receptor—a central nervous system receptor that binds hallucinogenic compounds, including LSD and psilocybin. Many hope to discover why these molecules cause hallucinations when they bind to 5-HT 2A while other compounds that bind to the receptor, including serotonin, do not. LSD and psilocybin have been shown to treat mood...

Psilocybin: Characterization of the Metastable Zone Width (MSZW), Control of Anhydrous Polymorphs, and Particle Size Distribution (PSD)

ACS Omega February 7, 2022 Robert B. Kargbo, Alexander M. Sherwood, Poncho Meisenheimer et al. 5 citations

Psilocybin, a serotonergic agonist, was granted a "breakthrough therapy" status by the Food and Drug Administration for clinical trials involving major depressive disorder and treatment-resistant depression. The direct phosphorylation of psilocin to psilocybin that uses a fast crystallization associated with a kinetically controlled process resulted in a smaller particle size distribution....

Analysis of Psilocybin-Assisted Therapy in Medicine: A Narrative Review

Cureus February 5, 2022 Shawn Ziff, Benjamin Stern, Gregory D. Lewis et al. 32 citations

Psilocybin-containing mushrooms have been consumed by various cultures in many different parts of the world for thousands of years. Psilocybin, a classic psychedelic, contains unique psychoactive properties and has been incorporated into religious ceremonies and investigated for its medicinal value. In the mid-20th century, psilocybin, along with most other classic psychedelics (5HT-2A...

Investigational drugs for assisting psychotherapy for posttraumatic stress disorder (PTSD): emerging approaches and shifting paradigms in the era of psychedelic medicine

Expert Opinion on Investigational Drugs February 1, 2022 Lynnette A. Averill, Chadi G. Abdallah

The unfortunate reality of the mental health crisis plaguing much of the world, in tandem with and exacerbated by the COVID-19 pandemic [1–3], highlights the limited effective pharmacologic treatments in our toolbox for posttraumatic stress disorder (PTSD). There are only two FDA-approved medications indicated for PTSD, both selective serotonin reuptake inhibitors (SSRIs). Though these...

Classic Psychedelic Drugs: Update on Biological Mechanisms

Pharmacopsychiatry January 25, 2022 John W Smallridge, Franz X. Vollenweider 107 citations

Abstract Renewed interest in the effects of psychedelics in the treatment of psychiatric disorders warrants a better understanding of the neurobiological mechanisms underlying the effects of these substances. During the past two decades, state-of-the-art studies of animals and humans have yielded new important insights into the molecular, cellular, and systems-level actions of psychedelic...
