Pexiganan

Description:

Pexiganan is a synthetic antimicrobial peptide that is primarily used for its antibacterial properties, particularly against Gram-negative bacteria. It is derived from the magainin family of peptides, which are naturally occurring in the skin of certain amphibians. Pexiganan exhibits a broad spectrum of activity, making it effective in treating infections, especially in topical formulations for wounds. The mechanism of action involves disrupting bacterial cell membranes, leading to cell lysis. This peptide is characterized by its relatively small size, typically consisting of around 22 amino acids, and its cationic nature, which enhances its interaction with negatively charged bacterial membranes. Pexiganan is also notable for its stability and resistance to proteolytic degradation, which contributes to its efficacy in clinical applications. Its development has been particularly focused on addressing the growing concern of antibiotic resistance, providing an alternative approach to traditional antibiotic therapies. Overall, Pexiganan represents a promising candidate in the field of antimicrobial agents, particularly for topical use.

Pexiganan

CAS: 147664-63-9

Pexiganan is a polymyxin B derivative that has potent antimicrobial activity against both Gram-positive and Gram-negative bacteria. It has been shown to be effective in the treatment of tissue infections, especially those caused by human pathogens such as Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. Pexiganan also has significant activity against Mycobacterium tuberculosis and other mycobacteria. The mechanism of action for pexiganan is not fully understood but it may involve the inhibition of bacterial cell wall synthesis, or the disruption of bacterial membranes. Pexiganan was originally isolated from a marine sponge off the coast of Australia in 1961. It had been classified as an antimicrobial peptide (AMP) because of its chemical structure, which includes a polymyxin B moiety. Pexiganan’s AMP classification was later challenged when researchers found that it did
