to develop new antibacterial drugs with novel mechanism of action. Here we designed and synthesized three series of benzoxazolone, oxazolopyridinone and 3-(2-hydroxyphenyl)hydantoin derivatives and evaluated their activity as novel quorum sensing (QS) inhibitors. We found that benzoxazolone and oxazolopyridinone derivatives had promising QS inhibitory activity in the minimum inhibitory concentration

antibacterial agents with novel mechanisms to treat infections caused by drug-resistant bacteria. In this paper, we designed and synthesized 2-phenoxyalkylhydrazide benzoxazole derivatives and evaluated their quorumsensing inhibition activity. Among them, 26c at a concentration of 102.4 μg/mL not only inhibited the production of pyocyanin and rhamnolipid by 45.6% and 38.3%, respectively, but also suppressed
