Abstract

Official abstract text for this publication.

Provided are 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.

First claim

Opening claim text (preview).
