Introduction: Quorum sensing inhibition (QSI) is one of the vital tools to overcome emerging virulence of pathogenic bacteria which aims at curbing bacterial resistance. Targeting QS (quorum sensing) as chemotherapy is less likely to generate resistance among pathogens as it targets only the adaptation and not the survival mechanism of the pathogen. Several QS inhibitors were developed in the recent past but none of them managed to have clinical application due to known toxic effects for human consumption. A rapid development of QS inhibitor drugs could be achieved by verification of the QSI activity of drugs which are already in clinical use with known pharmacology...
