Function&Application
Polymyxin B is a kind of anti-Gram-negative poly-peptide antibiotics which can alter membrane structure allowing small molecules leakage and inhibit the growth of Gram-negative bacteria. It has bactericidal effect on Escherichia coli through binding to the lipid A portion of bacterial lipopolysaccharide. Mechanism of action: bind and interfere with the permeability o the cellular membrane. Anti-bacteria spectrum: gram negative bacteria.
