Colistin Sulfate (1264-72-8) is a cyclic antimicrobial peptide targeting the outer membrane of Gram-negative bacteria It is designed to interact electrostatically with negatively charged lipopolysaccharides thereby disrupting membrane integrity and permeability Colistin Sulfate exerts its biological activity primarily through disruption of the bacterial outer membrane In bacterial inhibition assays Colistin Sulfate demonstrates inhibitory activity with IC50 values typically ranging from 0 5 5 g/mL depending on the bacterial strain and experimental conditions Based on these pharmacological properties Colistin Sulfate holds research potential in antimicrobial applications particularly against multidrug-resistant Gram-negative organisms and as a selective agent in bacterial cell culture protocols
