Quorum sensing-related gene expression (ftf, smu630, brpA, gbpB, gtfB, vicR, comDE and relA) was investigated by real-time polymerase chain reaction (RT-PCR). The results showed that synthetic furanone C-30 can inhibit biofilm formation by S. mutans and its luxS mutant strain, although it does not affect the bacterial growth rate itself. Introduction: Quorum sensing (QS) is a cell density-dependent phenomenon in which specific pathways are activated after autoinducers (AIs) outside the microorganism reach a threshold concentration. The previously certified and commercialized quorum sensing inhibitors were implicated in the clinical trials, even though their basic uses and specialized biological activity shows no association with bacterial quorum sensing, although they were cytotoxic and possess antimicrobial activities and were bactericidal [43, 44]. Introduction: Quorum sensing (QS) is a cell density-dependent phenomenon in which specific pathways are activated after autoinducers (AIs) outside the microorganism reach a threshold concentration.QS creates a positive feedback loop that induces a cascade of gene expression and causes biofilm formation, virulence and sporulation. inhibitors, inhibition of quorum sensing (QS) is a promising route because various important features ... Phase I–II clinical trials) may be avoided, leading to substantial savings for the pharmaceutical companies [39,53,54]. Although the costs of organizing Phase III–IV trials “Adding molecules called quorum-sensing inhibitors to current drugs not only reduces bacterial production of certain harmful residues but also restores the efficacy of existing treatments on the cells of cystic fibrosis patients,” explained Emmanuelle Brochiero, a researcher at the University of Montreal Hospital Research Centre (CRCHUM) and a professor at Université de Montréal. The purpose of this study is to assess the clinical efficacy of azithromycin, used as a quorum-sensing blocker, when compared to placebo for preventing or delaying the occurrence of pneumonia in ventilated patients colonized with Pseudomonas aeruginosa. Introduction: Quorum-sensing (QS) is a microbial cell-to-cell communication system that utilizes small signaling molecules to mediates interactions between cross-kingdom microorganisms, including Gram-positive and -negative microbes. QS molecules include N-acyl-homoserine-lactones (AHLs), furanosyl borate, hydroxyl-palmitic acid methylester, and methyl-dodecanoic acid. Introduction: Quorum sensing (QS) is a cell density-dependent phenomenon in which specific pathways are activated after autoinducers (AIs) outside the microorganism reach a threshold concentration.QS creates a positive feedback loop that induces a cascade of gene expression and causes biofilm formation, virulence and sporulation. These quorum sensing inhibitors (QSIs) can competitively inhibit QS signaling system, providing an opportunity to develop new drugs against these targets to combat pathogens. This review focuses primarily on natural and synthetic QSIs targeting different components of the QS and their potential applications in medical fields.
