Abstract: | The synthesis and biofilm inhibitory activity of a 30-member aryl amide 2-aminoimidazole library against the three biofilm forming Gram-negative bacteria Escherichia coli, Psuedomonas aeruginosa, and Acinetobacter baumannii is presented. The most active compound identified inhibits the formation of E. coli biofilms with an IC50 of 5.2 μM and was observed to be non-toxic to planktonic growth, demonstrating that analogues based on an aryl framework are viable options as biofilm inhibitors within the 2-aminoimidazole family. |
