Bacterial quorum-sensing molecule analogs having the following structures:
and methods of reducing bacterial pathogenicity, comprising providing a biological system comprising pathogenic bacteria which produce natural quorum-sensing molecule; providing a synthetic bacterial quorum-sensing molecule having the above structures and introducing the synthetic quorum-sensing molecule into the biological system comprising pathogenic bacteria. Further is provided a method of targeted delivery of an antibiotic, comprising providing a synthetic quorum-sensing molecule; chemically linking the synthetic quorum-sensing molecule to an antibiotic to produce a quorum-sensing molecule-antibiotic conjugate; and introducing the conjugate into a biological system comprising pathogenic bacteria susceptible to the antibiotic.
具有以下结构的细菌群体感应分子类似物以及减少细菌致病性的方法,包括提供一个生物系统,其中包含产生天然群体感应分子的致病细菌;提供具有上述结构的合成细菌群体感应分子,并将合成群体感应分子引入包含致病细菌的生物系统。此外还提供了一种靶向传递抗生素的方法,包括提供合成群体感应分子;将合成群体感应分子与抗生素化学连接以产生群体感应分子-抗生素结合物;并将结合物引入一个对抗生素敏感的包含致病细菌的生物系统中。
