Description

一般描述

Polymyxin B is a member of the polymyxin group of antibiotics, obtained from different strains of Bacillus polymyxa and related species. It contains a cyclic heptapeptide unit and a tripeptide side chain, which is N-acylated by a fatty acyl residue. Polymyxin B sulfate salt is generally used for the treatment of Gram-negative bacterial infections.
Chemical structure: peptide

应用

Polymyxin B sulfate salt has been used:

• for the treatment of BAC-1.2F5 murine macrophages as an LPS (lipopolysaccharide) inhibitor
• as positive and negative control during microbicidal concentration (MCC) assay

包装

1000000, 5000000 units

生化/生理作用

Polymyxin B sulfate has been used clinically to treat infections of the urinary tract, meninges and blood stream caused by susceptible strains of Pseudomonas aeruginosa. It also has been used in studying multidrug-resistant pathogens, as an immobilized agent for removal of endotoxins, and to induce pore formation in the membranes of cortex cells from excised sorghum roots.

作用方式：多粘菌素B硫酸盐结合到细菌脂多糖的脂质部分†上，通过诱导足够大的孔来破坏细胞质膜，使核苷酸泄漏到细菌的细胞壁中。 这可破环细胞质膜的半透性。

抗菌谱：对大多数革兰氏阴性杆菌，包括 大肠杆菌 ，真菌和革兰氏阳性菌都有杀菌作用。

注意

As supplied, the product should be stored at 2-8°C in the dark. No change was observed in retained samples after three years′ of storage in these conditions. Stock solutions should be sterile filtered and stored at 2-8°C. They are stable at 37°C for 5 days.

制备说明

Polymyxin B sulfate is soluble in water at 50 mg/mL, producing a very slightly hazy, colorless to yellow solution. It has only minimal solubility in any organic solvent. For example, it has a solubility of 0.115 mg/mL in ethanol.
