Figure Legend Snippet: Figure 3. Membrane permeabilization assays of 16 in E. coli ATCC 25922. Polymyxin B was included as a comparator membrane-targeting agent. Both 16 and polymyxin B were used at concentrations ranging from 1/32X to 1/2X the minimum inhibitory concentration (MIC), with the MIC values of 16 and polymyxin B being 100 and 1.56 µg/ml, respectively. The compound vehicle was DMSO. (A,B) Impact of E. coli treatment with 16 (A) or polymyxin B (B) on the intensity of the fluorophore N- phenyl-1-naphthylamine (NPN) at a concentration of 10 µM. (C,D) Impact of treatment with 16 (C) or polymyxin B (D) on the percentage of E. coli cells stained with the fluorophore propidium iodide (PI) at a concentration of 50 µM.
Techniques Used: Membrane, Concentration Assay, Staining
Figure Legend Snippet: Figure 4. Assay for inhibition of the efflux of the fluorophore Hoechst 33342 (H33342) by 16 in E. coli ATCC 25922. When present, 16 was used at concentrations ranging from 1/32X to 1/2X MIC (3.13 to 50 µg/mL). All reactions were initiated by the addition of 50 mM glucose except where indicated. H33342 was used at a concentration of 10 µM. Compound vehicle was DMSO.
Techniques Used: Inhibition, Concentration Assay
