Abstract
Provided herein are compounds that can exhibit activity as biofilm modulating agents (e.g., activity as biofilm inhibitors and/or activity as biofilm dispersal agents). The compounds can exhibit potent activity against Gram positive biofilms. The compounds can also exhibit activity against Gram negative biofilms. In some cases, the compounds can exhibit both biofilm modulation properties and antimicrobial activity. Compositions comprising these compounds, as well as methods of using thereof, are also described. For example, the compounds described herein can be used in human and animal health (e.g., for the treatment of infection), agriculture, marine coatings, and other coating applications related to prevention of biofilm (e.g., dental, medical, etc.).
