Phosphorylated and Branched Dihydroxy-Pentane-Dione (DPD) Analogs as Quorum Sensing Inhibitors in Bacteria

Abstract 

This patent covers compositions and methods for modulating quorum sensing in microbes. The compounds are AI-2 analogs and as such have structures similar to 4,5-dihydroxy-2,3-pentanedione that can act as agonists/antagonists of quorum sensing. The compounds are useful for modulating quorum sensing in bacteria and can be used in methods for prophylaxis or therapy of bacterial infections and for reduction of biofilms.
