Squarylated lactones inhibitors for bacterial biofilm formation

摘要

A library of unnatural squarylated homoserine lactones (SHLs) and squarylated lactones that bear potential to modulate biofilm formation in Gram negative bacteria. At low concentrations (˜200 μM), these small molecules inhibit biofilm formation of E. coli. Moreover, these compounds are not toxic up to 300 μM and do not significantly attenuate E. coli growth. The SHLs have potential to disperse established biofilm and demonstrate an enhanced reduction (˜50%) of the maximum biofilm thickness by use of SHLs during biofilm growth.
