New N-acyl homoserine lactone analogues, N-acyl-3-amino-5H-furanone derivatives and some 4-halogeno counterparts, were synthesised and tested for their ability to modulate LuxR-dependent bacterial quorum sensing. Both types of analogues proved to be inhibitors, the halogenated compounds being significantly more active. Molecular modelling suggested that the conjugated enamide group induces two preferential
合成了新的N-酰基高丝氨酸内酯类似物,N-酰基-3-氨基-5H-呋喃酮衍生物和一些4-卤代对应物,并测试了它们调节LuxR依赖性细菌群体感应的能力。两种类型的类似物均被证明是抑制剂,卤代化合物的活性明显更高。分子建模表明,共轭烯酰胺基团诱导两个优先构象,导致特定的结合模式。此外,卤素原子的存在可以通过与LuxR蛋白家族中严格保守或可保守取代的残基,即Asp79,Trp94和Ile81的特定相互作用,增强内酯环的拟合。
