ABSTRACT
The aim of this study was to evaluate the caffeic acid (1) and ester derivatives (2-10) against Candida albicans biofilm and to investigate whether these compounds are able to inhibit the biofilm formation or destroy pre-formed biofilm. Caffeic acid ester 7, cinnamic acid ester 8 and 3,4-dihydroxybenzoic acid ester 10 are more active than fluconazole, used as reference drug, both on biofilm in formation with MIC50 values of 32, 32 and 16µg/mL, respectively, and in the early stage of biofilm formation (4h) with MIC50 values of 64, 32 and 64µg/mL, respectively. These esters result also more active than fluconazole on mature biofilm (24h), especially 8 and 10 with MIC50 values of 64µg/mL.
