DOI: 10.1007/s00216-020-02534-7
Abstract: Homoserine lactones (HSLs) are signaling molecules synthesized by Gram-negative bacteria in order to communicate in a process termed “quorum sensing.” Until recently, only the l -stereoisomers of HSLs were thought to be produced and able… read more here.

DOI: 10.1007/s00253-017-8697-3
Abstract: Bacteria can coordinate and synchronize activities through a cell density-dependent regulatory mechanism called quorum sensing (QS). Bacteria can measure their population by the synthesis, secretion, and perception of QS signal molecules to regulate specific gene… read more here.

DOI: 10.1016/j.bioorg.2020.104307
Abstract: The synthesis and the QS modulation activity of diastereoisomerically pure 2-hydroxy-N-acyl-l-homoserine lactones (2-OH-AHLs) are unveiled. (2R)- and (2S)- 2-hydroxy-N-hexanoyl-l-homoserine lactone and 2-hydroxy-N-octanoyl-l-homoserine lactone have been identified as very potent QS agonists and antagonists on the… read more here.
