In recent years, metabotropic glutamate receptor 5 (mGluR5) has attracted considerable attention for its crucial role in regulating glutamatergic transmission. In this review, we conducted a search of PubMed, Web of Science and Science Direct databases to explore the relationship between mGluR5 and depression, and summarized the antidepressant effects and mechanisms of action of various mGluR5 negative allosteric modulators (NAMs) based on the literatures in the past five years. A total of 112 articles meeting the screening criteria were included this review. We found that the pathological process of depression was accompanied by abnormally elevated levels of mGluR5 expression, and its hyperactivation might be involved in disease progression by impairing neuroplasticity. In addition, mGluR5 had the potential to interact with classical depressive targets. Accordingly, mGluR5 NAMs exerted antidepressant effects by directly or indirectly modulating synaptic plasticity, suppressing inflammatory responses, and regulating molecular pathways. Based on literature reports of mGluR5 NAMs, we conducted selective molecular docking simulations to validate their strong binding. Finally, we summarized the efficacy and safety data of mGluR5 modulators that had entered clinical trials. In conclusion, targeting the mGluR5 is a promising strategy to address the clinical need for more effective treatments for patients with depression, but the safety still needs attention.</div></div>","PeriodicalId":314,"journal":{"name":"European Journal of Medicinal Chemistry","volume":"297 ","pages":"Article 117976"},"PeriodicalIF":6.0,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144645678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inspired by previously reported delocalized lipophilic cations (DLCs) based on styryl dye framework, we introduce a series of seventeen novel styrene dyes, several of which exhibit enhanced optical properties compared to their parent compounds. Most dyes display strong Stokes shifts (104–112 nm), primarily due to the indolyl chromophore, with minimal influence from other substituents. These dyes bind noncovalently to the grooves of ds-DNA/RNA with moderate affinity, responding by significantly increased fluorescence. The selected derivatives effectively penetrate living human cells, accumulating primarily in mitochondria and becoming highly fluorescent.
