Interactions of naturally occurring compounds with antimicrobials

Area of Science:

• Pharmacology
• Microbiology
• Natural Product Chemistry

Background:

• Antibiotics are crucial in healthcare and agriculture but face challenges like resistance and toxicity due to overuse.
• Natural products have a long history in medicine and possess antibacterial properties.
• Combining natural compounds with antibiotics offers a strategy to reduce antibiotic usage and mitigate adverse effects.

Purpose of the Study:

• To review natural compounds and their interactions with commercial antibiotics.
• To explore the potential of natural products in developing novel antibacterial therapies.
• To identify both beneficial (synergistic/additive) and detrimental (antagonistic) interactions.

Main Methods:

• Literature review of natural compounds (terpenes, alkaloids, flavonoids, tannins, sulfoxides, mycotoxins).
• Analysis of documented drug interactions between natural compounds and antibiotics.
• Evaluation of reported effects on bacterial strains and therapeutic outcomes.

Main Results:

• Many natural compounds exhibit synergistic or additive interactions with antibiotics.
• These interactions suggest potential for reduced antibiotic dosage, decreased toxicity, and slowed resistance development.
• Conversely, some natural compounds show antagonistic effects, potentially compromising antibacterial efficacy.
• Interaction outcomes are dependent on the compound's mechanism, the specific antibiotic, and the bacterial strain.

Conclusions:

• Natural compounds hold promise for augmenting antibacterial therapy by enhancing antibiotic efficacy and reducing side effects.
• Careful selection and understanding of compound-antibiotic interactions are critical to avoid antagonistic effects.
• Further research into specific natural compounds and their mechanisms is warranted for optimized antibacterial drug development.
