Bacteria communicate (quorum sensing) via secretion of signal molecules (auto inducers). This communication is highly associated with their ability to form biofilms and consequently pathogenicity. We have synthesized novel simple heterocyclic compounds, synthesized to resemble the biological functions of the natural auto inducers. Those agents act as agents or antagonists to the cell cell communication therefore affecting biofilm formation and thereafter the virulence of the bacteria. The agents can be used as simple molecules or in corporate into a coating. Our agents affect also fungi biofilms.
The novelty of the invention is that those agents are acting as alternative mean to antibiotics as they do not affect vitality of microorganisms only reduce virulence. Side effects regularly associated with antibiotics are not indicative using our invention.
Yissum tells NWN that their technology will impact various industries, including:
- Medical: The prevention and removal of biofilms in human diseases.
- Water: Prevention and removal of biofilms from pipes, membranes
- Environmental: Affect biofilms in households, using environmental agents
