Abstract |
Nosocomial infections by fungi are important causes of morbidity and mortality, and the adhesion capacity of yeast on abiotic and biotic surfaces has been considered an important step in this process. Als3 proteins are widely studied for their ability to allow Candida albicans to bind to various surfaces. The objective of the present study was to verify, with more details, the action of F2768-0318 in relation to its antifungal activity as well as its ability to act on C. albicans virulence factors related to adhesion and biofilm formation in vitro and in vivo by inhibiting the Als3 protein. F2768-0318 was assessed in tests of biofilm formation and adhesion on abiotic surfaces (polystyrene plates) and adherence on biotic surfaces, including human endocervical (HeLa) cells, human umbilical vein endothelial cells (HUVECs), and fresh buccal epithelial cells (BEC). Our results showed F2768-0318 was useful in reducing the adhesion and biofilm formation of C. albicans on abiotic surfaces, indicating the possibility of treating hospital materials and preventing biofilm formation on these types of equipment. Further studies are still needed, including optimization of the molecule to allow this molecule to be effective on other types of surfaces, such as human cells.
