RESUMO
Objective To develop some 3-aminooxazolidin-2-one derivatives with bacteria quorum sensing(QS) inhibitory activity. Methods Using (2-hydroxyethyl) hydrazine as raw material, we finished the synthesis through cyclization, condensation, hydrolysis and condensation reaction, and evaluated their inhibition of QS via Chromobacterium violaceum. Results Eight compounds were synthesized and their structures were confirmed by 1H NMR and MS characterization. Compounds Z2 had inhibitory effect against QS. Conclusion None of the eight synthesized compounds have been reported before and the synthetic route is reliable. Compounds Z2 have inhibitory effect against QS.

RESUMO
Bacterial N-Acyl-L-homoserine lactones (AHLs)-mediated quorum sensing is involved in the regulation of diverse biological functions. As the bacterial pathogen population density increases, AHLs concentration secreted by pathogen reaches a threshold and then interacts with their intercellular receptor and triggers expression of virulence genes. It is a promising approach to biologically control bacterial disease in plants and animals by manipulating bacterial AHL-quorum sensing with AHLs-degrading enzyme and AHL analogue.
