Natural Phenolics Disrupt Microbial Communication by Inhibiting Quorum Sensing.

ABSTRACT: Quorum sensing, a bacterial cell-to-cell communication mechanism, plays a key role in bacterial virulence and biofilm formation. Targeting quorum-sensing pathways represents a promising strategy for the development of novel antibacterial agents. This study evaluated the anti-quorum-sensing activities of 18 natural compounds, including cannabinoids, arylbenzofurans, flavonoids, caffeine, and chlorogenic acid, using the luminescent biosensor strain Vibrio harveyi MM30. V. harveyi MM30, a mutant strain deficient in the production of autoinducer-2 (AI-2) but responsive to exogenous AI-2, was used to assess the activity of test compounds on the AI-2 receptor pathway. Test compounds were incubated in AI-2-containing media, and luminescence was measured to evaluate quorum-sensing in
