Anti-quorum quenching activity of methyl gallate isolated from galls of Guiera senegalensis J.F Gmel (Combretaceae)

Many pathogenic bacteria produce virulence factors controlled by a mechanism of regulation named quorum sensing (QS). Inhibition of bacterial QS system is a more recent therapeutic approach to counterbalance the emergence of multi-drug resistant bacteria. This study aimed to assess the abilities of methanol extract from Guiera senegalensisgalls and its isolated compound methyl gallate to quench the quorum sensing system....
