The chemical synthesis and antibiotic activity of a diverse library of 2-aminobenzimidazole small molecules against MRSA and multidrug-resistant A. baumannii
摘要:
Multidrug-resistant bacterial infections continue to be a rising global health concern. Herein is described the development of a class of novel 2-aminobenzimidazoles with antibiotic activity. These active 2-aminobenzimidazoles retain their antibiotic activity against several strains of multidrug-resistant Staphylococcus aureus and Acinetobacter baumannii when compared to susceptible strains.

Disclosure is provided for imidazole-triazole derivative compounds that prevent, remove and/or inhibit the formation of biofilms, compositions comprising these compounds, devices comprising these compounds, and methods of using the same.
Anti-biofilm agents have been developed based upon the flustramine family of alkaloids isolated fromFlustrafoliacea. A Garg interrupted Fischer indolization reaction was employed to access a core pyrroloindoline scaffold that was subsequently employed to create a pyrroloindoline triazole amide library.

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.
