SPR206 (acetate)

SPR206 acetate is a polymyxin analog with antibiotic activity against Gram-negative pathogens, including multidrug-resistant (MDR) variants. SPR206 acetate has an anti-bacterial infection effect by interacting with the bacterium’s outer membrane. The MIC values of SPR206 acetate against Pseudomonas aeruginosa Pa14 and Acinetobacter baumannii NCTC13301 are both 0.125 mg/L[1][2].
