Biochem/physiol Actions

Iberin is a natural isothiocyanates from cruciferous vegetables (cabbage, red cabbage, horseradish) that potently inhibits toll-like receptors (TLRs) signaling. Iberin covalently binds to TLR4 and TLR2, which inhibits TLR dimerization. Iberin exhibits potent antioxidant, anticancer, and antimicrobial activities. It is quorum-sensing inhibitor (QSI) of the bacterial pathogen Pseudomonas aeruginosa through downregulation of the Gac/Rsm QS network.

We evaluated the potentials of 10 isothiocyanates (ITCs) from cruciferous vegetables and radish root hydrolysate for inhibiting the growth of oral pathogens, with an emphasis on assessing any structure-function relationship. Structural differences in ITCs impacted their antimicrobial activities against oral
