Abstract

The incidence of fungal infections, especially those caused by Candida yeasts, has increased in recent decades. Vulvovaginal candidiasis (VVC) is an opportunistic infection that causes significant problem to women's health. These yeasts present several virulence factors, such as, biofilm formation, morphological transition between yeast and hyphae, adhesion and production of hydrolytic enzymes and others. The therapy for control of fungal infections, especially to azole compounds, polyene and echinocandins, has limitations such as high cost, high toxicity, drug interactions, inadequate bioavailability of the active ingredient, in addition to the emergence of resistant strains. In this sense, the medicinal plants are an alternative in the search for new antifungal agents. Syngonanthus nitens (Bong.) Ruhland and Cymbopogon nardus (L.) Rendle has shown promising results against pathogenic fungi of the genus Candida. Additionally, nanotechnology is presented as a tool to antifungal activity of natural products. In this study we aimed to evaluate the antifungal potential of these plant species employing the pharmaceutical nanotechnology as a tool to enhance the action of plant derived against three species of yeast: C. albicans, C. krusei and C. glabrata, focusing the control of the VVC. The activity of plant derivatives loaded in nanostructured systems of drug delivery (lipid microemulsion) will be determinated in order to improve its antifungal action. In vitro assays will be employed with emphasis on monotypical biofilms (C. albicans, C. glabrata and C. krusei) and heterotypic (+ Lactobacillus sp) and in vivo assays will be performed with Wistar rats (Rattus norvegicus) (AU)
