SPR206 Acetate(Cat No.:I044328)is a next-generation polymyxin derivative developed to combat multidrug-resistant Gram-negative bacterial infections. Engineered for improved safety and reduced nephrotoxicity compared to polymyxin B and colistin, SPR206 retains potent antimicrobial activity against critical pathogens such as Pseudomonas aeruginosa, Acinetobacter baumannii, and Klebsiella pneumoniae. It functions by disrupting bacterial membranes, leading to rapid cell death. SPR206 Acetate is a valuable compound for antimicrobial research, particularly in the development of new treatments targeting carbapenem-resistant and extensively drug-resistant bacterial strains. Ideal for studies in antimicrobial resistance and drug development.
