Evaluation of antifungal activity of glycoalkaloids from the Solanum lycocarpum St. Hil (lobeira) in the cell membrane of dermatophyte of Trichophyton rubrum

چکیده
Background The dermatophytes belong to one of the main groups of pathogenic fungus, characterized by the use of the host’s keratin for its nutrition, which are the most common cause of fungal infection in the world, affecting millions of individuals annually, causing a huge economic impact [1]. Therefore, there was an increase in the search for new antifungal agents from natural sources, because the majority of the available drugs in the market presents a restricted number of cellular targets and there are reports of resistant fungal strain to these utilized drugs [2]. Glycoalkaloids from the Solanum lycocarpum plant (lobeira) presents several biological activities, such as cytotoxic and antimicrobial activities [3]. The goal of this work was determination the Minimum Inhibitory Concentration (MIC) of the solanine, solamargine and solasodine from the S. lycocarpum in addition to evaluate the effect of these alkaloids in the regeneration of the Trichophyton rubrum cell wall.

Background Phytochemical analysis of the fruits of Solanum lycocarpum, popularly known as “fruit of the wolf”, showed high concentrations of steroidal alkaloids, such as solasonine and solamargine which are substances with potential cytotoxic activity [1]. The cytotoxic activity displayed by these compounds may be due to presence of sugar moieties (rhamnose). Since there is interaction of glyco...

Solanum lycocarpum St.-Hil popularly known as ‘fruta-de-lobo’ or ‘lobeira’ is native to the Brazilian Cerrado, and used in folk medicine due to its phytotherapic properties. The action of S. lycocarpum on the cell cycle and chromosomes in order to demonstrate whether there are aneugenic and/or clastogenic effects is unknown. Thus, this study aimed at investigating the cytotoxic and genotoxic po...

Background Trichophyton rubrum is a dermatophyte that causes mostly superficial mycoses in skin, hair and nails, but an invasive course has been described in immunocompromised patients [1]. The resistance to usual antifungal drugs has been observed in T.rubrum what drives an increasing demand for new antifungal drugs. Chalcones are flavonoids found in plants that exhibit pronounced antifungal a...
