In the context of the growing global threat posed by multidrug-resistant fungal pathogens, especially species of the &lt;em&gt;Candida&lt;/em&gt; genus, exploring natural sources like &lt;em&gt;E. uniflora&lt;/em&gt; for antifungal drug development is both timely and necessary.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Aim of the study&lt;/h3&gt;&lt;div&gt;Evaluating the antifungal activity of a spray-dried leaf extract of &lt;em&gt;E. uniflora&lt;/em&gt; (SDEEu) against &lt;em&gt;Candida&lt;/em&gt; spp. (&lt;em&gt;C. albicans&lt;/em&gt;, &lt;em&gt;C. glabrata&lt;/em&gt;, and &lt;em&gt;C. auris&lt;/em&gt;) using in vitro assays and in silico modeling.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Material and methods&lt;/h3&gt;&lt;div&gt;The hydroalcoholic extract was spray-dried and subjected to antifungal evaluation. Antifungal activity was initially assessed by determining the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) against &lt;em&gt;Candida albicans&lt;/em&gt;, &lt;em&gt;C. glabrata&lt;/em&gt;, and &lt;em&gt;C. auris&lt;/em&gt;. To analyze time-dependent inhibitory effects, growth kinetics were monitored. Membrane integrity and morphological alterations were investigated using flow cytometry and scanning electron microscopy. Mechanistic assays included ergosterol-binding and biofilm inhibition analyses. Checkerboard assays were conducted to evaluate synergistic interactions with amphotericin B and nystatin. Finally, molecular docking simulations were performed to assess the binding affinity of major phytochemicals to fungal enzymes involved in membrane and cell wall biosynthesis.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;The extract exhibited promising antifungal activity, particularly against &lt;em&gt;C. glabrata&lt;/em&gt; and &lt;em&gt;C. auris&lt;/em&gt;, with MIC and MFC values of 31.25 μg/mL and 62.50 μg/mL, respectively. The growth curve revealed sustained inhibition over 48 h, particularly during the early metabolic adaptation phase. SDEEu induced predominantly necrotic cell death in all tested strains, while &lt;em&gt;C. glabrata&lt;/em&gt; also exhibited apoptotic features, accompanied by marked morphological alterations such as membrane disruption and loss of budding. The extract showed strong interaction with membrane sterols and synergistic effects with amphotericin B and nystatin, notably reversing resistance in &lt;em&gt;C. auris&lt;/em&gt;, the most drug-resistant strain, with FICI values as low as 0.022. Furthermore, SDEEu inhibited biofilm formation in all strains, reaching up to 50 % inhibition in &lt;em&gt;C. albicans&lt;/em&gt;. In silico docking studies demonstrated strong binding affinities of myricitrin with squalene monooxygenase (−7","PeriodicalId":15761,"journal":{"name":"Journal of ethnopharmacology","volume":"352 ","pages":"Article 120181"},"PeriodicalIF":4.8,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144469893","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}
