Product information "Polymyxin B (sulfate)"
The polymyxins are cationic peptides originally isolated from B. polymyxa. They bind and kill Gram-negative bacteria. The B series of polymyxins consist of a cyclic heptapeptide and a tripeptide side chain acylated at the amino terminus by a fatty acid. Polymyxin B (sulfate) is a mixture of at least four closely related components, polymyxin B1 to B4, with polymyxin B1 (Cay-14074) and B2 being the two major components. Polymyxin B (sulfate) has rapid in vitro bactericidal activity against major multidrug-resistant Gram-negative bacteria, such as P. aeruginosa, A. baumannii, and K. pneumoniae.Formal Name: N-(4-amino-1-((1-((4-amino-1-oxo-1-((6,9,18-tris(2-aminoethyl)-15-benzyl-3-(1-hydroxyethyl)-12-isobutyl-2,5,8,11,14,17,20-heptaoxo-1,4,7,10,13,16,19-heptaazacyclotricosan-21-yl)amino)butan-2-yl)amino)-3-hydroxy-1-oxobutan-2-yl)amino)-1-oxobutan-2-yl)-6-methyloctanamide sulfate.
