Antifungal Activity of Spent Coffee Ground Extracts
Calheiros, Daniela; Dias, Maria Inês; Calhelha, Ricardo C.; Barros, Lillian; Ferreira, Isabel C. F. R.; Fernandes, Chantal; Gonçalves, TeresaCoffee is one of the most popular and consumed products in the world, generating tons of solid waste known as spent coffee grounds (SCG), containing several bioactive compounds. Here, the antifungal activity of ethanolic SCG extract from caffeinated and decaffeinated coffee capsules was evaluated against yeasts and filamentous fungi. These extracts had antifungal activity against Candida krusei, Candida parapsi...

Correia, Edmilson Emanuel Monteiro; Figueirinha, Artur; Rodrigues, Lisa; Pinela, José; Calhelha, Ricardo C.; Barros, Lillian; Fernandes, ChantalWithania chevalieri, endogenous from Cape Verde, is a medicinal plant used in ethnomedicine with a large spectrum of applications, such as treating skin fungal infections caused by dermatophytes. The aim of this work was to chemically characterize the W. chevalieri crude ethanolic extract (WcCEE), and evaluate its bioactivities as antidermatophytic, antioxidant, anti-inflammatory and anticancer, as well as its ...

Pyomelanin synthesis in alternaria alternata inhibits DHN-Melanin synthesis and...
Fernandes, Chantal; Mota, Marta; Barros, Lillian; Dias, Maria Inês; Ferreira, Isabel C.F.R.; Piedade, Ana P.; Casadevall, Arturo; Gonçalves, TeresaThe genus Alternaria includes several of fungi that are darkly pigmented by DHNmelanin. These are pathogenic to plants but are also associated with human respiratory allergic diseases and with serious infections in immunocompromised individuals. The present work focuses on the alterations of the composition and structure of the hyphal cell wall of Alternaria alternata occuring under the catabolism of L-tyrosine...

The antifungal activity of extracts of Osmundea pinnatifida, an edible seaweed,...
Silva, Paulo; Fernandes, Chantal; Barros, Lillian; Ferreira, Isabel C.F.R.; Pereira, Leonel; Gonçalves, TeresaIn the present work, we explored the antifungal activity of the wild edible seaweed Osmundea pinnatifida (Rhodophyta) collected from the Portuguese coast, which is used as a food seasoning in Scotland, Ireland and Portugal. We performed a sequential extraction of the seaweed components with methanol, dichloromethane and n-hexane. These extracts showed an antifungal activity against Alternaria infectoria and Aspe...

Diogo, Patrícia; Mota, Marta; Fernandes, Chantal; Sequeira, Diana; Palma, Paulo; Caramelo, Francisco; Neves, M. Graça P. M. S.; Faustino, M Amparo F.The aim of this study was to assess antimicrobial efficacy and cytotoxic outcomes of a chlorophyll based photosensitizer (PS) Zn(II)chlorin e6 methyl ester (Zn(II)e6Me), when applied to human dentin discs and root blocks infected with 48 h biofilms. The results were compared with the ones obtained with FotoSan® (commercial Toluidine Blue O formulation) and 3% sodium hypochlorite (NaOCl).
Antimicrobial Photodynamic Therapy against Endodontic Enterococcus faecalis and...
Diogo, Patrícia; Fernandes, Chantal; Caramelo, Francisco; Mota, Marta; Miranda, Isabel M.; Faustino, M. A. F.; Neves, M. G. P. M. S.Endodontic biofilms eradication from the infected root canal system remains as the primary focus in endodontic field. In this study, it was assessed the efficacy of antimicrobial Photodynamic Therapy (aPDT) with the Zn(II)chlorin e6 methyl ester (Zn(II)e6Me) activated by red light against monospecies and mixed biofilms of Enterococcus faecalis and Candida albicans. The results were compared with the ones obtain...
