N-acyl homoserine lactones (AHLs) are signal molecules used by a large number of gram-negative bacteria in quorum sensing and their hydrolysis is known to inhibit biofilm formation. Micellar imprinting of AHL-like templates with catalytic functional monomers yielded water-soluble nanoparticles with AHL-shaped active site and nearby catalytic groups. Either Lewis acidic zinc ions or nucleophilic pyridyl ligands could be introduced through this strategy, yielding artificial enzymes for the hydrolysis of AHLs in a substrate-selective fashion.

用于群体感应中细菌自诱导剂选择性水解的合成纳米颗粒。
N-酰基高丝氨酸内酯(AHL)是大量革兰氏阴性细菌在群体感应中使用的信号分子,已知其水解会抑制生物膜的形成。用催化功能单体在AHL样模板上进行胶束印迹,得到具有AHL形活性位和附近催化基团的水溶性纳米颗粒。可以通过此策略引入Lewis酸性锌离子或亲核吡啶基配体,从而产生以底物选择性方式水解AHL的人工酶。
