Chemical structure: peptide

アプリケーション

Polymyxin B sulfate is a strongly cationic cyclic polypeptide antibiotic that is derived from fermentation of Bacilus polymyxa. It is a mixture of B1 and B2 sulfate. The product 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 uses 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.

生物化学的／生理学的作用

作用機序：ポリミキシンB硫酸塩は、細菌リポポリサッカライド†の脂質A部分と結合し、細菌壁内にヌクレオチドの漏出を可能にするのに十分大きな細孔を誘導することにより細胞膜を破壊します。 これは細胞膜の透過性を破壊します。

抗菌スペクトル：大腸菌（E.coli）を含むほとんどのグラム陰性桿菌††、ならびにほとんどの菌類およびグラム陽性菌に対し殺菌作用を有します。

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.

調製ノート

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. This product is biotechnology performance certified.
