產(chǎn)品描述: | Polymyxin B nonapeptide TFA 是一種陽(yáng)離子環(huán)肽。Polymyxin B nonapeptide TFA 是經(jīng)酶裂解 Polymyxin B 而產(chǎn)生的衍生物,與 Polymyxin B 相比,Polymyxin B nonapeptide TFA 毒性低,缺乏殺菌活性,仍具有破壞革蘭氏陰性菌外膜的能力。 |
體外研究: |
Polymyxin B nonapeptide, a cationic cyclic peptide derived by enzymatic processing from the naturally occurring peptide polymyxin B, is able to increase the permeability of the outer membrane of Gram-negative bacteria toward hydrophobic antibiotics probably by binding to the bacterial lipopolysaccharide (LPS). |
