Summary
Coumarins, plant-derived compounds, can disrupt bacterial communication (quorum sensing) and inhibit biofilm formation, offering a novel strategy to combat antibiotic resistance and enhance antimicrobial effectiveness.
Area of Science:
- Microbiology
- Natural Product Chemistry
- Pharmacology
Background:
- Quorum sensing (QS) is a critical bacterial communication system influencing pathogenesis and antibiotic resistance via biofilm formation.
- Biofilm formation is a key factor in persistent infections and reduced susceptibility to antibiotics.
- Plant-derived coumarins possess diverse bioactivities and are explored for antimicrobial applications.
Purpose of the Study:
- To review quorum sensing (QS) and biofilm formation mechanisms in bacteria.
- To explore the role of coumarins in modulating QS and inhibiting biofilm development.
- To highlight the potential of coumarins in combating antibiotic resistance.
Main Methods:
- Literature review of quorum sensing, biofilm formation, and coumarin bioactivities.
- Analysis of studies investigating coumarin effects on bacterial communication and biofilms.
- Examination of synergistic interactions between antibiotics and coumarins.
Main Results:
- Coumarins demonstrate the ability to interfere with bacterial quorum sensing pathways.
- Coumarins effectively inhibit the formation and development of bacterial biofilms.
- Combinations of antibiotics with coumarins show enhanced antimicrobial activity and reduced resistance.
Conclusions:
- Coumarins represent a promising class of compounds for developing novel anti-infective strategies.
- Targeting QS and biofilms with coumarins can overcome existing antibiotic resistance mechanisms.
- Coumarin-based therapies hold potential for alleviating the global challenge of antibiotic resistance.

3
Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...

1
Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...

01:30Bacterial Signaling
31.6K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...
