Description
SPR741 (NAB741) is a cationic peptide derived from polymyxin B and is a potentiator molecule. SPR741 increases the permeability of the outer membrane of Gram-negative bacteria and is used to treat severe Gram-negative bacteria infections. SPR741 inhibits multidrug-resistant Gram-negative bacteria. The spectrum of activity of the antibiotic can be widened when used in combination with SPR741[1][2].
