The preparation of a collection of 131 small molecules, reminiscent of families of long chain N-acyl tyrosines, enamides and enol esters that have been isolatedfromheterologous expression of environmentalDNA (eDNA) in Escherichia coli, is reported. The synthetic libraries of N-acyl tyrosines and their 3-keto counterparts were prepared via solid-phase routes, whereas the enamides and enol esters
据报道,制备了 131 个小分子的集合,让人联想到长链 N-酰基酪氨酸、烯酰胺和烯醇酯家族,这些分子是从大肠杆菌环境 DNA (eDNA) 的异源表达中分离出来的。N-酰基酪氨酸及其3-酮对应物的合成库是通过固相途径制备的,而烯酰胺和烯醇酯是在溶液相中合成的。

with virulence. Thus the selective disruption of AHL-based quorumsensing represents a strategy to attenuate the pathogenicity of this bacterium. Herein we describe the design, synthesis and biologicalevaluation of a collection of structurally novel AHL mimics. A number of new compounds capable of modulating the LasR-dependent quorumsensing system of P. aeruginosa were identified, which could have

Antivirulence strategies to combat Pseudomonas aeruginosa, are described. One strategy encompasses synthesis of a series of compounds that inhibit the production of pyocyanin, a redox-active virulence factor produced by this pathogen. A related strategy encompasses synthesis of compounds that inhibit the two P. aeruginosa quorum-sensing receptors, LasR and RhlR, inhibit production of pyocyanin, and inhibit biofilm formation.

decline in the development of new antimicrobialtherapeutics has coincided with the emergence of new and more aggressive multidrug-resistant pathogens. Pathogens are protected from antibiotic activity by their ability to enter an aggregative biofilm state. Therefore, disrupting this process in pathogens is a key strategy for the development of next-generation antimicrobials. Here, we present a suite of
