一般說明

Chemical structure: peptide

應用

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

作用机制: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。

包裝

This product is packaged in a bottomless glass bottle, with its contents inside an inserted fused cone.

The Journal of antimicrobial chemotherapy, 73(2), 452-455 (2017-11-18)
Extremely multiresistant strains of Enterobacteriaceae, such as those of Escherichia coli and Klebsiella pneumoniae, are emerging and spreading at a worrisome speed. Polymyxins (polymyxin B, colistin) are used as last-line therapy against such strains, in spite of their notable nephrotoxicity
Mei-Ling Han et al.
ACS chemical biology, 13(1), 121-130 (2017-11-29)
Polymyxins are last-line antibiotics against life-threatening multidrug-resistant Gram-negative bacteria. Unfortunately, polymyxin resistance is increasingly reported, leaving a total lack of therapies. Using lipidomics and transcriptomics, we discovered that polymyxin B induced lipid A deacylation via pagL in both polymyxin-resistant and
Martti Vaara et al.
Peptides, 91, 8-12 (2017-03-17)
Recent years have brought in an increased interest to develop improved polymyxins. The currently used polymyxins, i.e. polymyxin B and colistin (polymyxin E) are pentacationic lipopeptides that possess a cyclic heptapeptide part with three positive charges, a linear "panhandle" part

PloS one, 3(9), e3151-e3151 (2008-09-06)
It has been established that c-Jun N-terminal kinase 1 (JNK1) is essential to the pathogenesis of insulin resistance and type 2 diabetes. Although JNK influences inflammatory signaling pathways, it remains unclear whether its activity in macrophages contributes to adipose tissue
Amit Kumar et al.
Scientific reports, 7, 39925-39925 (2017-01-05)
To become clinically effective, antimicrobial peptides (AMPs) should be non-cytotoxic to host cells. Piscidins are a group of fish-derived AMPs with potent antimicrobial and antiendotoxin activities but limited by extreme cytotoxicity. We conjectured that introduction of cationic residue(s) at the
