. Additionally, the compounds resulted in the silencing of transposition-related genes, potentially inhibiting resistance-gene acquisition and expression. Phloretin regulated fatty acid metabolism pathways, which are related to the construction and maintenance of the cell membrane. This suggests a relationship between the structure and antibacterial activities of the tested compounds that share a flavonoid skeleton but differ in the C-ring and glucose moiety. This is the first report of the antibacterial activities and mechanisms of action of food-derived dihydrochalcone flavonoids at the transcriptome level, offering a promising approach for the development of new antibacterial agents from natural products and enhancing their applicability in treating diseases associated with oral pathogens as a substitute for antibiotics.
