Furthermore, these mushrooms also contain bioactive primary metabolites, for example, the interesting case of \u03b1,\u03b1-trehalose. To explore the effects of this disaccharide, it was isolated and characterized using phytochemical and spectroscopic analyses. Subsequently, its anxiolytic- and antidepressant-like properties were assessed and corroborated by in vivo behavioral studies using experimental models for anxiety (open-field, hole-board, and plus-maze tests) and depression (forced swimming test complemented by a preliminary rota-rod test). Electrocorticographic in situ recordings and nuclear magnetic resonance analysis were also explored. Finally, an in silico docking analysis was performed to determine the involvement of the 5-HT1A serotonin receptor as one of the main targets identified in the CNS activity of Psilocybe species. The evidence shows that \u03b1,\u03b1-trehalose is one bioactive metabolite that promotes significant anxiolytic- and antidepressant-like activities mediated by early brain changes and involving an indirect participation of 5-HT1A receptors. In conclusion, \u03b1,\u03b1-trehalose represents a potential natural drug for mental health, such as in the treatment of anxiety, depression, or their comorbidity.<\/jats:p>","DOI":"10.3390\/molecules31193383","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T11:09:08Z","timestamp":1790161748000},"page":"3383","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Preclinical Anxiolytic- and Antidepressant-like Effects of \u03b1,\u03b1-Trehalose, a Bioactive Compound Identified in Psilocybe cubensis"],"prefix":"10.3390","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-5552-4710","authenticated-orcid":false,"given":"Ayl\u00edn Roc\u00edo","family":"Tabal-Robles","sequence":"first","affiliation":[{"name":"Laboratorio de Neurofarmacolog\u00eda de Productos Naturales, Direcci\u00f3n de Investigaciones Biom\u00e9dicas en Salud Mental, Instituto Nacional de Psiquiatr\u00eda Ram\u00f3n de la Fuente Mu\u00f1iz, Calz.
