Fig. 8. Confocal images and quantification of cyclic variants when compared to UBI-3. Panels show methicillin-sensitive Staphylococcus aureus incubated with cyclic UBI compounds (all 10 μM) with quantification of bacterial fluorescence normalized to UBI-3 (bars represent mean (±SEM), n ≥ 3, ns = not significant, ** = p < 0.01, scale bar = 10 μm).
