SPR741

Catalog No.: A46373
Antibiotic
SPR741 is a cationic peptide antibiotic derived from polymyxin B, functioning primarily as a potentiator. It enhances the permeability of the outer membrane in Gram-negative bacteria, making it an effective agent against multidrug-resistant strains. SPR741 is utilized in research focused on severe Gram-negative infections and can broaden the spectrum of activity when used in combination with other antibiotics.
