Medchemexpress LLC Colistin, sulfate (salt) | 1264-72-8 | >98.0% | C52H98N16O13.2.5H2O4S | 1 ML
Colistin sulfate is a polypeptide antibiotic that inhibits gram-negative bacteria by binding to lipopolysaccharides and phospholipids in their outer cell membrane. It is intended for research use only.
- Polypeptide antibiotic
- Inhibits gram-negative bacteria by binding to lipopolysaccharides and phospholipids in their outer cell membrane, and by electrostatically interfering with the outer membrane by competitively displacing divalent cations from the negatively charged phosphate groups of membrane lipids
- Bactericidal to gram-negative bacteria with a narrow spectrum of activity
- Associated with slow development of resistance for treating infections caused by multidrug-resistant gram-negative bacteria
- Available as colistin (sulfate) mainly for topical use, and colistin methanesulfonate (sodium) for parenteral use
