The emergence of antibiotic-resistant bacteria has exacerbated the challenge of treating infectious diseases. Quorum sensing (QS), a bacterial communication system regulating virulence and biofilm formation, presents a target for novel therapies. Cuproptosis death is a innovation mode of death, however, this effect may be partially inhibited by glutathione (GSH). Buthionine sulfoximine (BSO) is responsible for GSH biosynthesis and has been identified as a potential promoter of cuproptosis death. Here, Cu
