(2018). Quorum sensing inhibitors: a patent review (2014–2018) Expert Opinion on Therapeutic Patents: Vol. 28, No. 12, pp. 849-865. INTRODUCTION: Quorum sensing (QS) is a cell-to-cell communication that regulates gene expression and coordinates their behavior in accordance with the cell population density as a result of discerning molecules termed autoinducers (AIs). The processes that QS governed include biofilm formation, bacterial virulence, antibiotic production, competence, conjugation, swarming motility and sporulation. Three main QS AIs are acyl-homoserine lactones, AI-2 and AI peptides. The attractive study of QS BACKGROUND: Quorum sensing (QS) is a microbial cell-cell signaling system that correlates gene expression with cell population density. It plays important roles in intra-species communications and is also involved in inter-species and microbe-host interactions. Because QS controls a wide spectrum of phenotypes including virulence and biofilm formation, inhibition of QS may provide alternative therapeutic methods for treating microbial infections. OBJECTIVE: To provide an overview of QS This review focuses primarily on natural and synthetic quorum sensing inhibitors (QSIs) with the potential for treating bacterial infections. It has been opined that the most versatile prokaryotes... The phenomenon is also termed as quorum quenching (QQ). In addition, synthetic compounds have also been found to be effective in QQ. This review focuses primarily on natural and synthetic quorum sensing inhibitors (QSIs) with the potential for treating bacterial infections. It has been opined that the most versatile prokaryotes to produce QSI are likely to be those, which are generally regarded as safe. Among the eukaryotes, certain legumes and traditional medicinal plants are likely to act Quorum sensing inhibitors: an overview. Biotechnol Adv. 2013; 31(2):224-45 (ISSN: 1873-1899) Kalia VC. Excessive and indiscriminate use of antibiotics to treat bacterial infections has lead to the emergence of multiple drug resistant strains. Most infectious diseases are caused by bacteria which proliferate within quorum sensing (QS) mediated biofilms. Efforts to disrupt biofilms have enabled Because of its promising effect as an alternative to antibiotics, quorum sensing disruption is an intensively studied field, and there are many studies that describe the quorum sensing inhibitory activity of natural and synthetic compounds. In this opinion article, we present an overview of recent literature with respect to quorum sensing inhibitors. Most of this research is based on experiments with quorum sensing signal molecule reporter strains. However, these experiments are prone to 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. The overall objective is to identify a system, which has the potential for exploitation in controlling bacterial infections without stressing the bacterial The phenomenon is also termed as quorum quenching (QQ). In addition, synthetic compounds have also been found to be effective in QQ. This review focuses primarily on natural and synthetic quorum sensing inhibitors (QSIs) with the potential for treating bacterial infections. It has been opined that the most versatile prokaryotes to produce QSI are likely to be those, which are generally regarded as safe. Among the eukaryotes, certain legumes and traditional medicinal plants are likely to act These molecules act primarily by quenching the QS system.
