Abstract
Cell adhesion plays a crucial role in candidiasis through invasion of the human body and obtaining resistance to drugs by forming biofilms. Cell adhesion thus is a critical target for combating candidiasis by preventing the entry of fungal hyphae into the epithelium. We report here that dehydrocurvularin (1), isolated from the marine-derived fungus Curvularia aeria, exhibited anti-fungal activities for Candida albicans and Candida auris. This compound also prevented the adherence of C. albicans to human adenocarcinoma cells. Real-time RT-PCR analysis showed that exposure to 1 results in decreased expression of HWP1, EFG1, and ECE1, genes involved in Candida adhesion to epithelial cells and hyphal morphogenesis.
