The present disclosure encompasses compounds and compositions that are useful as specific AI-2 antagonists for the control of bacterial quorum sensing. Although the AI-2 antagonists according to the present disclosure may not have bactericidal effect, their ability to attenuate virulence, drug resistance, and/or biofilm formation have therapeutic benefits. In addition, the AI-2 antagonists of the present disclosure can also be used as tools to probe bacterial AI-2 functions. The present disclosure also encompasses methods for inhibiting or attenuating microbial virulence, biofilm formation, and drug resistance. The methods are suitable for preventing bacteria from accruing and forming extensive biofilms that may be a health or hygiene hazard or a physical issue, such as in the blockage of water or fuel lines.
本公开包括可作为特异性 AI-2 拮抗剂用于控制细菌法定人数感应的化合物和组合物。尽管本公开的 AI-2 拮抗剂可能不具有杀菌作用,但其减弱毒性、耐药性和/或生物膜形成的能力具有治疗效果。此外,本公开的 AI-2 拮抗剂还可用作探究细菌 AI-2 功能的工具。本公开内容还包括抑制或减弱微生物毒力、生物膜形成和耐药性的方法。这些方法适用于防止细菌积累和形成广泛的生物膜,这些生物膜可能会危害健康或卫生,或造成物理问题,如堵塞水管或燃油管。
