설명

애플리케이션

Polymyxin B nonapeptide hydrochloride has been used as an outer membrane permeabilizer, to characterize PAßN activity on membrane. It has been used as a control in antibacterial assays.

생화학적/생리학적 작용

PMBN has endotoxin-neutralizing activity and thus can be utilized in adjunctive therapy against Gram-negative sepsis. It has been found that PMBN is less toxic than polymyxin B. Unlike polymyxin B, PMBN does not exhibit neurotoxicity and nephrotoxicity. While it retains the anti endotoxin property of the parent compound, it is much less potent.

Polymyxin B nonapeptide (PMBN), a cationic cyclic peptide derived from the antibacterial peptide polymyxin B, specifically increases the permeability of the outer membrane of Gram-negative bacteria toward hydrophobic antibiotics. PMBN has been used to evaluate multidrug efflux inhibitors in E. coli.

Polymyxin B nonapeptide hydrochloride is a derivative of PMB that induces outer membrane permeability in gram-negative bacteria.
