  "abstract": "Purpose\n\nInvasive candidiasis and increasing antifungal resistance underscore the need for alternative therapeutic approaches. Antimicrobial peptides are of interest because of their antifungal activity and potential membrane-associated effects. This study evaluated Hyde C1, a plant-derived antimicrobial peptide from Cichorium intybus, for antifungal activity against Candida albicans and examined whether its effects were associated with fungal membrane-associated effects.Methods\n\nAntifungal activity against C. albicans ATCC 10231 was assessed using minimum inhibitory concentration (MIC), minimum fungicidal concentration (MFC), and time-kill assays. Membrane permeability and cellular morphology were examined by propidium iodide uptake, transmission electron microscopy, and scanning electron microscopy. Molecular docking assessed the predicted interaction of Hyde C1 with a model yeast membrane environment. Therapeutic effects were evaluated in a cyclophosphamide-induced murine model of systemic candidiasis by assessing survival, kidney fungal burden, and renal histopathology.Results\n\nHyde C1 showed antifungal activity with an MIC of 16 μg/mL and an MFC of 32 μg/mL. Time-kill analysis showed concentration- and time-dependent reductions in fungal viability. Hyde C1 increased propidium iodide uptake and produced ultrastructural and surface morphological alterations in fungal cells, findings consistent with membrane-associated antifungal activity. Docking analysis indicated a favorable predicted interaction with the model yeast membrane environment. In vivo, Hyde C1 treatment improved survival, reduced kidney fungal burden, and was associated with less pronounced infection-related renal histopathological changes than in untreated infected mice.Discussion\n\nHyde C1 exhibited antifungal activity against C. albicans and protective effects in a murine model of systemic candidiasis. The combined in vitro, computational, and in vivo findings support further investigation of this plant-derived peptide as an antifungal therapeutic candidate with membrane-associated activity. Additional studies are required to define its molecular mechanism, pharmacokinetic properties, safety profile, and reproducibility across broader experimental models.",
