From: Calcium-chelating alizarin and other anthraquinones inhibit biofilm formation and the hemolytic activity of Staphylococcus aureus

Figure 3

Inhibition of biofilm formation by alizarin-related chemicals.

Chemical structures are shown (a). Hydroxyl groups are shown in red and the two hydroxyls at C-1 and C-2 of anthraquinone are shown in blue. Biofilm formation by MSSA 6538 was quantified in the presence of selected chemicals after incubation for 24 h in 96-well polystyrene plates without shaking (b). At least two independent experiments were conducted (6 wells per sample). Error bars indicate standard deviations. *P < 0.05 versus non-treated controls (None).
