Efficient synthesis and evaluation of quorum-sensing modulators using small molecule macroarrays.
A method for the synthesis of small molecule macroarrays of N-acylated L-homoserine lactones (AHLs) is reported. A focused library of AHLs was constructed, and the macroarray platform was found to be compatible with both solution and agar-overlay assays using quorum-sensing (QS) reporter strains. Several QS antagonists were discovered and serve to showcase the macroarray as a straightforward technique for QS research.
