Modulating the development of E. coli biofilms with 2-aminoimidazoles
摘要:
The synthesis of a 20 member 2-aminoimidazole/triazole pilot library is reported. Each member of the library was screened for its ability to inhibit or promote biofilm development of either Escherichia coli and Acinetobacter baumannii. From this screen, E. coli-selective 2-aminoimidazoles were discovered, with the best inhibitor inhibiting biofilm development with an IC(50) of 13 mu M. The most potent promoter of E. coli biofilm formation promoted biofilm development by 321% at 400 mu M. (C) 2010 Elsevier Ltd. All rights reserved.

been shown to promote carbon–carbon coupling between benzene and aryl halides in the presence of potassium tert-butoxide and without the assistance of a transition metal catalyst. The structure of the diketopiperazine has an influence on its reductive potential and can help to promote the coupling of the more challenging aryl bromides with benzene.
