Abstract
Quorum sensing (QS) is an important microbial signaling system that controls the expression of many virulence genes. Combination treatment with QS inhibitors and antibiotics may be the new treatment option for infectious diseases in the future. Therefore, there is an increasing need to discover anti-QS compounds to prevent antimicrobial resistance. We isolated methyl-β-D-glucopyranoside from Scabiosa comosa and found that it exerts an anti-QS activity against Chromobacterium violaceum CV026 without exhibiting any antimicrobial activity.
