Exploring the anti-biofilm activity of cinnamic acid derivatives in Candida albicans

Bioorg Med Chem Lett. 2016 Dec 15;26(24):5931-5935. doi: 10.1016/j.bmcl.2016.10.091. Epub 2016 Nov 1.

Abstract

Some compounds, characterized by phenylethenyl moiety, such as methyl cinnamate and caffeic acid phenethyl ester, are able to inhibit C. albicans biofilm formation. On these bases, and as a consequence of our previous work, we synthesized a series of cinnamoyl ester and amide derivatives in order to evaluate them for the activity against C. albicans biofilm and planktonically grown cells. The most active compounds 7 and 8 showed ⩾50% biofilm inhibition concentrations (BMIC50) of 2μg/mL and 4μg/mL respectively, against C. albicans biofilm formation; otherwise, 7 showed an interesting activity also against mature biofilm, with BMIC50 of 8μg/mL.

Keywords: Biofilm; Candida albicans; Cinnamic esters; Cinnamoyl amides.
