These symptoms can be alleviated by α1β2γ2GABA-A receptor ligands, which have previously shown antipsychotic activity. Building on this foundation, we synthesized and characterized various derivatives of 2-phenylimidazo[1,2-<i>a</i>]-pyridine containing cyclic amine moieties at the amide backbone to identify potent ligands and expand the chemical space of α1β2γ2GABA-A receptor ligands. The synthesized compounds exhibited <i>K</i><sub>i</sub> values ranging from 25.0 to 7822.5 nM and positive allosteric properties at α1β2γ2GABA-A receptors. Selected compounds exhibited promising cellular permeability properties, high metabolic stability, and neuroprotective activity. A representative derivative of this series elicited antipsychotic-like properties, reversing amphetamine- and MK-801-induced hyperlocomotion without inducing sedative effects. Our findings indicate that α1β2γ2GABA-A ligands represent a promising strategy for the identification of potential antipsychotic agents with an original mechanism of action.</p>","PeriodicalId":13,"journal":{"name":"ACS Chemical Neuroscience","volume":" ","pages":"2277-2294"},"PeriodicalIF":4.1,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12186843/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144245192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Classic psychedelics, including psilocybin, lysergic acid diethylamide (LSD), and <i>N</i>,<i>N</i>-dimethyltryptamine (DMT), primarily act on serotonin 5-HT<sub>2A</sub> receptors and have emerged as potential modulators of pain perception and mood regulation. These substances may offer an alternative to conventional analgesics, such as opioids and nonsteroidal anti-inflammatory drugs (NSAIDs), by influencing neuroplasticity, descending pain modulation pathways, and inflammatory processes. Evidence from case studies, preclinical research, and early phase clinical trials suggests that psychedelics may alleviate pain in conditions such as cluster headaches, migraines, fibromyalgia, and chronic pain syndromes. However, the exact mechanisms underlying their analgesic properties are yet to be fully understood. While psychedelics show promise in reshaping pain management strategies, rigorous randomized controlled trials are needed to establish their safety, efficacy, and optimal dosing. This review highlights the therapeutic potential of psychedelics for chronic pain and emphasizes the necessity of further research to validate their role in modern pain medicine.</p>","PeriodicalId":13,"journal":{"name":"ACS Chemical Neuroscience","volume":" ","pages":"2163-2177"},"PeriodicalIF":4.1,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12183689/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
