Résumé
Background: Resistance against antifungals used for Candida albicans (Ca) treatment is mediated by two multidrug transporters, Mdr1p and Cdr1p, which are of enormous interest to the development of modulators combined with antifungals. Results: A set of chalcones were screened using the checkerboard liquid chemosensitization assays. Compounds 4, 10, 12 and 18, when combined with fluconazole, triggered strong sensitization on yeast strains overexpressing CaMdr1p and CaCdr1p, whereas displaying no cytotoxic by themselves towards control strains and transporter-expressing yeast cells. In the Nile Red (NR) transport assay, the two most active compounds 12 and 18 showed moderate-to-high accumulation of NR with different behaviors towards the two transporters. Conclusion: Chalcones are promising drug candidates for further development to make azole antifungals active again.
