Polymyxin E2 sulfate

CAS: 7239-48-7

Polymyxin E2 sulfate is a cyclic polypeptide antibiotic, which is derived from the bacterium *Paenibacillus polymyxa*. This compound acts by disrupting the bacterial cell membrane, specifically interacting with the lipopolysaccharides and phospholipids in the outer membrane, leading to increased permeability and eventual cell death. It primarily targets gram-negative bacteria, making it effective against a range of pathogens responsible for serious infections.
