antimicrobial amp defense history
Overview
Antimicrobial peptides (AMPs) represent an ancient defense mechanism that has inspired modern antibiotic development.
Key Discoveries
- 1981: Cecropins isolated from silk moths
- 1985: Defensins characterized in mammals
- 1987: Magainins found in frog skin
- 1990s: LL-37 cathelicidin discovered
- 2000s: First AMP clinical trials
- 2010s: Engineered AMPs enter development
Challenges
Despite potent in vitro activity, most AMPs have failed in clinical trials due to toxicity, stability, and efficacy issues.
Current Status
Optimized AMPs and synthetic mimics continue in development for resistant infections and topical applications.
