Next-Generation MDMA Analogue SDMA: Pharmacological and Metabolic Insights

ACS Chemical Neuroscience December 2, 2025 Nina Kastner, Núria Nadal‐gratacós, Selina Hemmer et al.

3,4-Methylenedioxymethamphetamine (MDMA), commonly known as ecstasy, shows promise in treating depression and post-traumatic stress disorder (PTSD), resulting in breakthrough status. However, concerns regarding MDMA's abuse potential and cytotoxicity have sparked interest in developing safer analogues with similar therapeutic benefits. This study investigated the pharmacological properties of...

A comparative assessment of the antidepressant efficacy of ketamine, psilocybin, and fluoxetine in a chronic stress model

Scientific Reports November 26, 2025 Małgorzata Domżalska, Joanna Kwiatkowska, Iwona Cichoń et al. 2 citations

Depression is a debilitating mental disorder affecting millions worldwide, yet current pharmacological treatments, such as selective serotonin reuptake inhibitors (SSRIs), often exhibit delayed onset and limited efficacy. The chronic social defeat (CSD) stress model in mice is a well-established preclinical paradigm for inducing depression-like behaviors and evaluating antidepressants...

Possible Involvement of Hallucinogenic Effects in the Aversive Effects Induced by Kappa‐Opioid and 5‐ HT 2A / 2C Receptor Agonists in Mice

Neuropsychopharmacology Reports November 23, 2025 Hideaki Kato, Yoshimi Ichimaru, Masaaki Kurihara et al. 1 citation

AIM: The regulation of new psychoactive and dangerous abused substances is very important for the prevention of drug abuse. A simple and effective evaluation method using laboratory animals is needed to regulate designated drugs with high accuracy and speed. METHODS: receptor agonist 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane hydrochloride (DOI), which have a similar mechanism of action to...

Psychedelics produce enduring behavioral effects and functional plasticity through mechanisms independent of structural plasticity

Neuropsychopharmacology November 12, 2025 Hannah M. Kramer, Meghan Hibicke, Jason W. Middleton et al. 7 citations

Activation of serotonin 2A (5-HT2A) receptors is thought to underly the long-lasting antidepressant effects of psychedelics such as psilocybin, but beyond that, the molecular and cellular mechanisms involved are not well understood. Recent preclinical studies using mice have primarily examined relatively short time points after psychedelic administration, which does not address the long-lasting...

5mC and 5hmC Detection Highlights How Psychedelics Affect Brain Epigenetic Patterns

Zenodo (CERN European Organization for Nuclear Research) November 4, 2025 Uri Bertocchi, Amit Schwartz, Gali Umschweif et al. preprint

Background: Psilocybin, a serotonergic psychedelic compound, has demonstrated long-term antidepressant effects, yet its underlying mechanisms remain unclear. Emerging evidence suggests that epigenetic modifications, particularly 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC), may play a role in its therapeutic action. Unlike passive demethylation, which requires cell division and...

Hormonal Influences on Psilocybin Responsivity Across the Female Lifespan: Toward Personalized Psychedelic-Assisted Therapy

Psychoactives November 2, 2025 Faith Ekoh, Shanice Rerrie, James Angud et al. 2 citations

Today’s research highlights the therapeutic potential of the hallucinogen psilocybin in the treatment of pathologies associated with mood, cognitive, and affective dysregulation. These domains of function are regulated by the serotonergic system, which can be influenced by sex hormones, like estrogen and testosterone, and psychedelic compounds including psilocybin. Current evidence supports a...

Psilocybin's effects on obsessive-compulsive behaviors: A systematic review of preclinical and clinical evidence

Psychedelics October 28, 2025 James J Gattuso, Bilgenur Bezcioglu, Carey Wilson et al. 1 citation

Psilocybin is a serotonergic psychedelic with growing evidence for efficacy in mood disorders, and its therapeutic potential in obsessive—compulsive disorder (OCD) and related conditions is increasingly recognised but remains understudied. We systematically evaluated clinical and preclinical evidence on psilocybin's effects on obsessive and compulsive behaviours with attention to translational...

Neuropharmacology of halogenated DMT analogs: psychoplastogenic and antidepressant properties of 5-Br-DMT, a psychedelic derivative with low hallucinogenic potential

Molecular Psychiatry October 21, 2025 Pol Puigseslloses, Núria Nadal‐gratacós, Berta Fumàs et al. 1 citation

Current first-line antidepressants, such as selective serotonin reuptake inhibitors (SSRI), often present a delayed onset of action and fail to effectively treat a large proportion of patients, leaving a gap in the treatment of mood disorders. Psychedelics have recently emerged as promising alternatives due to their ability to produce fast-acting antidepressant effects through neuroplastic...

LSD: Mechanisms and relevance to the treatment of depression

Neuroscience & Biobehavioral Reviews October 10, 2025 Amel Bouloufa, Sarah Delcourte, Thomas Delannay et al. 3 citations

Major depressive disorder (MDD) is one of the most prevalent psychiatric conditions worldwide, affecting over 350 million people. Standard treatments, primarily antidepressants targeting serotonin, noradrenaline, and/or dopamine, are based on the monoamine hypothesis, which links depression to imbalances in these neurotransmitters. A sizable fraction of patients, however, does not get enough...

Control group improvement lower in psilocybin trials for depression

The Brown University Psychopharmacology Update October 10, 2025

A meta‐analysis comprising 17 randomized trials has found that rates of control group improvement in depression studies were lower in psilocybin trials than in studies of esketamine or a selective serotonin reuptake inhibitor (SSRI). The results suggest that psilocybin's overall efficacy in the treatment of depression might be overestimated.
