Biochem/physiol Actions

Cationic antimicrobial peptide (AMP) with broad-spectrum activity against Gram-positive and Gram-negative bacteria.
Pexiganan (MSI-78) is a 22-aa synthetic cationic antimicrobial peptide (AMP), an analog of magainin found in the African clawed frog (Xenopus laevis). Pexiganan is effective against both Gram-positive (staphylococci MIC ≤16 µg/mL, streptococci & methicillin-resistant S. aureus MIC 8-64 µg/mL, S. pyrogenes MIC 16-256 µg/mL) and Gram-negative aerobes (MIC 4-32 µg/mL, E. cloacae MCI 1-128 µg/mL, A. faecalis 4-64 µg/mL) by disrupting bacteria cell wall or membrane.
