Inhibition of biofilm formation by quinone and anthraquinone related compounds. Chemical structures are shown. Hydroxyl groups are shown in blue and hydroxyl groups at para positions are in red (A). The antibiofilm activities of quinones and anthraquinones related compounds against C. albicans were determined after culturing for 24 h (B). Antibiofilm formation by selected compounds at low doses (C) none indicates non- treated samples. Two independent experiments were conducted (6 wells per sample); error bars indicate standard deviations. ^*p < 0.05 vs. non-treated controls.
