Searching for new agents active against candida albicans biofilm: a series of indole derivatives, design, synthesis and biological evaluation
Candida albicans biofilm represents a major clinical problem due to its intrinsic tolerance to anti-fungal compounds and it has been highly related to infections in catheterized patients. Few compounds are described as able to inhibit biofilm formation or to interfere with preformed biofilm of C. albicans. Here we report the in vitro evaluation of anti-biofilm activity on C. albicans ATCC 10231 of a series of new and already known amine and amide indole derivatives. Among the studied compounds, fifteen resulted active on C. albicans ATCC 10231 biofilm, with BMIC50 ≤ 16 μg/mL.
