Pharmacological Profile & Mechanism of Action
What it is: LL-37 is a 37-amino-acid antimicrobial peptide (AMP) representing the active functional cleavage fragment of human cathelicidin (hCAP-18).
How it works: LL-37 carries a strong net positive charge, allowing it to bind to negatively charged bacterial membranes and physically punch holes through them, causing rapid bacterial lysis. It destroys both Gram-positive and Gram-negative bacteria, dissolves protective bacterial biofilms, clears fungal pathogens, and recruits immune cells to wound sites.
Why researchers study it: Researched as a powerful natural antibiotic alternative, for eradicating antibiotic-resistant bacteria (MRSA, Pseudomonas), destroying bacterial biofilms, and accelerating chronic non-healing wound recovery.
