Background: Currently, there is a trend towards using natural and ethnopharmacological species with therapeutic potential. This investigation evaluated the antifungal activity of two species in the Ecuadorian Andes, which are used in treating dermatomycosis: Ambrosia arborescens Mill. (Marco) and Aristeguietia glutinosa Lam. (Matico). Methods: We worked with seven concentrations (100 to 700ppm) of Ambrosia arborescens Mill. extract and ten concentrations (0.5 to 5%) of essential oil (EO) of Aristeguietia glutinosa Lam. on Trichophyton mentagrophytes ATCC 9533, Trichophyton rubrum ATCC 28188, Microsporum canis ATCC 36299 and Candida albicans ATCC 10231. The methodology used was a modified version of the Kirby-Bauer method, using diffusion in agar wells. Results: The Tukey test, after the one-way Anova, determined effective concentrations of EO: 5% for Trichophyton mentagrophytes, 4.5% for Trichophyton rubrum, 5% for Microsporum canis and 2% for Candida albicans. In the extracts, the concentration of 700ppm was used for Trichophyton mentagrophytes, Trichophyton rubrum, and 600ppm for Microsporum canis and Candida albicans. Conclusions: The evaluation of the antifungal activity of the Ambrosia arborescens extract showed inhibition in the studied dermatophytes in each one of the planted concentrations (100 to 700ppm). The evaluation of the antifungal activity of Aristeguietia glutinosa EO showed inhibition in the studied dermatophytes in each of the planted concentrations (0.5 to 5%).

Background: Probiotic bacteria have been emerging as a trustworthy choice for the prevention and treatment of Candida spp. infections. This study aimed to develop and characterize an orodispersible film (ODF) for delivering the potentially probiotic Enterococcus faecium CRL 183 into the oral cavity, evaluating its in vitro antifungal activity against Candida albicans. Methods and Results: The ODF was composed by carboxymethylcellulose, gelatin, and potato starch, and its physical, chemical, and mechanical properties were studied. The probiotic resistance and viability during processing and storage were evaluated as well as its in vitro antifungal activity against C. albicans. The ODFs were thin, resistant, and flexible, with neutral pH and microbiologically safe. The probiotic resisted the ODF obtaining process, demonstrating high viability (>9 log10 CFU·g−1), up to 90 days of storage at room temperature. The Probiotic Film promoted 68.9% of reduction in fungal early biofilm and 91.2% in its mature biofilm compared to the group stimulated with the control film. Those results were confirmed through SEM images. Conclusion: The probiotic ODF developed is a promising strategy to prevent oral candidiasis, since it permits the local probiotic delivery, which in turn was able to reduce C. albicans biofilm formation.

Twenty-one substituted 1,4-naphthoquinones and five 8-quinolinols and copper(II) chelates were tested for antifungal activity against Candida albicans and Trichophyton mentagrophytes. Compounds containing electron-releasing or weak electron-withdrawing groups in the 2 and 3 positions of the 1,4-naphthoquinone ring were the most active against C. albicans at pH 7.0 in the presence of beef serum in the following order: 2-CH3O = 2,3-(CH3O)2 > 2-CH3 > 2-CH3S > 2-NH2 > 2,6-(CH3)2. For T. mentagrophytes under the same conditions the inhibitory 1,4-naphthoquinones contained the substituents 2-CH3O > 2,3-(CH3O)2 > 2-CH3S > 2-CH3 > 2-CH3(NaHSO3) > 2-NH2 > 2-C2H5S, 3-CH3 > 2,6-(CH3)2 > 2,3-Cl2 > 5,8-(OH)2.

Antifungal Efficacy

Background: Fluconazole (FLZ), a potent antifungal medication, is characterized by poor water solubility that reduced its antifungal efficacy. Objective: This study aimed to prepare FLZ-loaded polymeric nanoparticles (NPs) by using different polymers and techniques as a mean of enhancing the antifungal activity of FLZ. Methods: NP1, NP2, and NP3 were prepared by the double emulsion/solvent evaporation method using PLGA, PCL, and PLA, respectively. The ionotropic pre-gelation technique was applied to prepare an alginate/chitosan-based formulation (NP4). Particle size, zeta potential, encapsulation efficiency, and loading capacity were characterized. FT-IR spectra of FLZ, the polymers, and the prepared NPs were estimated. NP4 was selected for further in-vitro release evaluation. The broth dilution method was used to assess the antifungal activity of NP4 using a resistant clinical isolate of Candida albicans. Results: The double emulsion method produced smaller-sized particles (<390 nm) but with much lower encapsulation efficiency (< 12%). Alternatively, the ionic gelation method resulted in nanosized particles with a markedly higher encapsulation efficiency of about 40%. The FT-IR spectroscopy confirmed the loading of the FLZ molecules in the polymeric network of the prepared NPs. The release profile of NP4 showed a burst initial release followed by a controlled pattern up to 24 hours with a higher percent released relative to the free FLZ suspension. NP4 was able to reduce the value of MIC of FLZ by 20 times. Conclusion: The antifungal activity of FLZ against C. albicans was enhanced markedly via its loading in the alginate/chitosan-based polymeric matrix of NP4.

Abstract Spilanthol is a bioactive alkylamide from the native Amazon plant species, Acmella oleracea. However, antifungal activities of spilanthol and its application to the therapeutic treatment of candidiasis remains to be explored. This study sought to evaluate the in vitro and in vivo antifungal activity of spilanthol previously isolated from A. oleracea (spilanthol(AcO)) against Candida albicans ATCC® 10231™, a multidrug-resistant fungal strain. Microdilution methods were used to determine inhibitory and fungicidal concentrations of spilanthol(AcO). In planktonic cultures, the fungal growth kinetics, yeast cell metabolic activity, cell membrane permeability and cell wall integrity were investigated. The effect of spilanthol(AcO) on the proliferation and adhesion of fungal biofilms was evaluated by whole slide imaging and scanning electron microscopy. The biochemical composition of the biofilm matrix was also analyzed. In parallel, spilanthol(AcO) was tested in vivo in an experimental vulvovaginal candidiasis model. Our in vitro analyses in C. albicans planktonic cultures detected a significant inhibitory effect of spilanthol(AcO), which affects both yeast cell membrane and cell wall integrity, interfering with the fungus growth. C. albicans biofilm proliferation and adhesion, as well as, carbohydrates and DNA in biofilm matrix were reduced after spilanthol(AcO) treatment. Moreover, infected rats treated with spilanthol(AcO) showed consistent reduction of both fungal burden and inflammatory processes compared to the untreated animals. Altogether, our findings demonstrated that spilanthol(AcO) is an bioactive compound against planktonic and biofilm forms of a multidrug resistant C. albicans strain. Furthermore, spilanthol(AcO) can be potentially considered for therapeutical treatment of vulvovaginal candidiasis caused by C. albicans. Lay Abstract This study sought to evaluate the antifungal activity of spilanthol against Candida albicans ATCC® 10 231™, a multidrug-resistant fungal strain. Our findings demonstrated that spilanthol(AcO) can be potentially considered for therapeutical treatment of vulvovaginal candidiasis caused by C. albicans.

Erigeron Floribundus

L’usage des plantes médicinales connaît un regain d’intérêt. Cela est lié à la toxicité des produits chimiques, au coût élevé des médicaments chimiques, à l’éloignement et/ou l’insuffisance des centres de santé surtout en milieu rural. L’objectif général de cette étude était d’évaluer les potentialités thérapeutiques de l’huile essentielle des feuilles de l’espèce Erigeron floribundus utilisées en médecine traditionnelle en Côte-d’Ivoire. Les rendements en huile essentielle des feuilles d’Erigeron floribundus varient de 0,16 % pour les feuilles fraîches et de 0,31 % pour les feuilles séchées. Les indices physiques et chimiques de ces huiles essentielles sont en adéquation avec les critères de qualité des huiles essentielles selon la norme Afnor. L’effet antifongique des deux types d’huiles essentielles a été très remarquable sur les souches fongiques testées, notamment Trichophyton mentagrophytes et Aspergillus fumigatus, avec un effet moindre sur Candida albicans. Cette étude valide ainsi scientifiquement les usages traditionnels des extraits de la plante Erigeron floribundus en médecine traditionnelle.
