说明

化学结构：肽
硫酸多粘菌素B是一种强阳离子环状多肽抗生素，来源于多粘菌杆菌的发酵。它是B1和B2硫酸盐的混合物。该产品已在临床上用于治疗由易感铜绿假单胞菌菌株引起的尿路、脑膜和血流感染。该产品还用于研究多药耐药病原体，作为去除内毒素的固定化试剂，并诱导切除的高粱根皮层细胞膜中的孔形成。

一般描述

Chemical structure: peptide

应用

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.

生化/生理作用

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。
