Antibacterial of Dibenzo-p-Dioxi-28-Dicarboxylic Acid Against Pathogenic Oral Bacteria E. faecalis ATCC 29212 Peptide Pheromones: Quorum Sensing of in vitro and in silico Study

摘要

Recently, it has emerged from the international scientific literature that quorum sensing (QS) is a promising way for the effective treatment of diseases caused by pathogenic bacteria. One of the crucial proteins in the QS system of Gram-positive bacteria is the pheromone. Some research has reported secondary metabolites from natural products capable of attenuating bacteria through the interruption of the quorum sensing system. One of the Indonesian herbal plants containing bioactive compounds is Sarang Semut (Myrmecodia pendans). A phenolic compound, dibenzo-p-dioxin-2,8-dicarboxylic acid, has been isolated from this plant which had antibacterial activity against Enterococcus faecalis. However, the molecular mechanism of it has not been known.
