LL-37 amide is a selective agonist of formyl peptide receptor-like FPRL1, effectively inhibiting periodontal pathogens (ED99=8.5-8.7 μg/mL). LL-37 amide exerts its bactericidal effect by activating FPRL1-mediated immune cell chemotaxis and disrupting bacterial cell membrane integrity. It can also regulate inflammatory responses (inhibiting the release of factors such as TNF-α) and promote angiogenesis. Amidation modification reduces its sensitivity to serum inhibition and improves its stability. LL-37 amide possesses key activities in bactericidal action, immunomodulation, and wound healing, and is mainly used in research on infection-related diseases such as periodontal disease and deep tissue injuries (pressure ulcers), and wound healing .

Gramicidin S (Gramicidin soviet) is a cationic cyclic peptide antibiotic that selectively targets bacterial cell membranes and has anticancer activity. Gramicidin S also exerts antibacterial activity by destroying membrane integrity and interfering with membrane protein function. Gramicidin S inserts into the phospholipid bilayer through hydrophobic amino acid residues, specifically binds to negatively charged membrane lipids and disrupts membrane structure, thereby inhibiting cell division and cell wall synthesis, and ultimately causing bacterial death. Gramicidin S also inhibits ion channels, with IC50s of 41 μM, 24 μM, and 3 μM for Na +/K +-ATPase, tobacco leaf plasma membrane Mg 2+/K +-ATPase, and rat heart plasma membrane Ca 2+-ATPase, respectively .
