Polymyxin B nonapeptide TFA, the trifluoroacetic acid of Polymyxin B nonapeptide, is a potent and
naturally occurring cyclic peptide derived from Polymyxin B by proteolytic removal
of its terminal amino acyl residue. Polymyxin B nonapeptide is less
toxic, lacks bactericidal activity, and retains its ability to render
gram-negative bacteria susceptible to several antibiotics by
permeabilizing their outer membranes.
