(A) Comparison of piceatannol and their structural analogues at 200 μM in the crystal violet biofilm assay. (B) Fluorescence microscopy images of the S. mutans biofilms treated with 8 (200–50 μM). Green images correspond to bacteria stained with SYTO9, whereas blue images correspond to the fluorescent glucans within the biofilm tracked by the cascade blue-labeled dextran. (C) Two-dimensional diagram of the proposed residues interacting with piceatannol. (D) Docking pose of piceatannol (blue) and acarbose (green) in the GtfC active site.
