Emerging evidence suggests that classical psychedelics may offer therapeutic potential for opioid use disorder (OUD) by alleviating key hallmarks such as altered reward processing and dependence. However, the mechanisms behind these effects remain unclear. Our data demonstrate that a single administration of the psychedelic psilocybin (PSI) reduces conditioned behavior and withdrawal induced by...
Psychedelics have garnered significant interest for their therapeutic potential in mental health conditions such as depression, anxiety, and post-traumatic stress disorder. While research has primarily focused on well-studied psychedelics, phenethylamine derivatives have also gathered interest for their potential therapeutic applications. Thus, this study aims to investigate the pharmacological...
This study evaluated the effects of ibogalogs on recognition and spatial memory in rodents, focusing on potential hippocampal mechanisms. The Barnes maze study demonstrated that ibogaminalog (DM506) and ibogainalog (IBG) improved short- (30 min) and long-term (24 and 72 h) spatial memory in mice, whereas tabernanthalog (TBG) showed less efficacy. The novel object recognition task (NORT) results...
High Resolution Image Download MS PowerPoint Slide Recent patents unveil a new wave of psychedelic analogs optimized for 5-HT 2 A receptor modulation, reduced adverse effects, and tunable duration of action. By refining DMT and psilocin scaffolds through prodrug design, fluorination, and structure–activity exploration, these innovations promise safer, shorter-acting psychedelic medicines that...
Serotonergic psychedelics and 3,4-methylendioxtmethamphetamine (MDMA) are promising treatments for mental disorders with a continuously evolving evidence base. We searched Pubmed/Scopus/clinical trial registries up to 08july2025 for double-blind randomized controlled trials (RCTs) testing MDMA or serotonergic psychedelics in patients with mental disorders. Primary outcomes were change in...
Abstract Various ring-substituted α-methylphenethylamines (i.e., amphetamines) produce psychedelic-like effects that are primarily mediated by activity at 5-hydroxytryptamine 2A (5-HT 2A ) receptors. Small lipophilic substituents at the 4-position of the 2,5-dimethoxyamphetamine core structure can greatly enhance the clinical potency of such derivatives. Here, we studied the effects of various...

Abstract High-grade gliomas are the most aggressive form of brain tumors, and neuronal activity has emerged as a driver of glioma pathophysiology. Activity-dependent glioma growth results from paracrine factor signaling and bona fide neuron-to-glioma synapses that integrate glioma cells into brain-wide neuronal circuits. Here, we report how glioma cells integrate into serotonergic (5-HT)...

Regular recreational use of 3,4-methylenedioxymethamphetamine (MDMA, "Ecstasy") has been consistently linked to verbal memory dysfunctions, whose neurobiological origins remain unclear. Although neurochemical, structural, and functional alterations resulting from repeated MDMA intake have been identified in user populations, only limited knowledge exists regarding potential interrelationships...
Background: The treatment of major depressive disorder (MDD) with available antidepressant drugs is characterized by considerable ineffectiveness. Classical psychedelics such as psilocybin and N,N-dimethyltryptamine (DMT), which act primarily as 5-hydroxytryptamine 2A (5-HT 2A ) receptor agonists, have shown preliminary efficacy for inducing long-term remission in MDD after one or two doses....
