Abstract
Inhibition of quorum sensing is considered to be an effective strategy of control and treatment of a wide range of acute and persistent infections. Pseudomonas aeruginosa is an opportunistic bacterium with a high adaptation potential that contributes to healthcare-associated infections. In the present study, the effects of the synthesized hybrid structures bearing sterically hindered phenolic and heterocyclic moieties in a single scaffold on the production of virulence factors by P. aeruginosa were determined. It has been shown that the obtained compounds significantly reduce both pyocyanin and alginate production and stimulate the biosynthesis of siderophores in vitro, which may be attributed to their iron-chelating properties. The results of docking-based inverse high-throughput virtual screening indicate that transcription regulator LasR and Cu-transporter OPRC could be potential molecular targets for these compounds. Investigation of the impact small molecules exert on the molecular mechanisms of the production of bacterial virulence factors may pave the way for the design and development of novel antibacterial agents.
