Overview

Broad class of innate immune peptides with antimicrobial, immunomodulatory, and wound-healing properties representing next-generation anti-infectives.

Mechanism of Action

Diverse mechanisms including membrane disruption (pore formation, carpet model), LPS neutralization, biofilm inhibition, immunomodulation (chemotaxis, cytokine modulation), intracellular targeting, synergy with conventional antibiotics.

Key Benefits

  • ✓Broad-spectrum antimicrobial activity
  • ✓Low resistance development
  • ✓Immunomodulatory effects
  • ✓Anti-biofilm properties
  • ✓Wound healing support
  • ✓Synergy with antibiotics
  • ✓Novel infection treatment paradigm

Summary

Robust preclinical evidence across diverse AMPs. Multiple candidates in clinical development. Few approved therapeutics yet (e.g., colistin, polymyxin B for resistant infections). Represents promising frontier in anti-infective therapy with potential to address antibiotic resistance crisis.
