Chemical structure: peptide
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.
Polymyxin B sulfate salt has been used:
• in human aortic endothelial cells (HAEC) cell culture to exclude potential endotoxin contamination in recombinant adiponectin
• in the analysis of the isolates
• in endotoxin-neutralizing activity of α-amylase (AmyI-1)-18 (LAL assay)
