Putative complexes formed by clotrimazole, clofoctol, and miconazole with the PqsR CBD. Schematic representations of the complexes formed by clotrimazole (A), clofoctol (B), and miconazole (C) with the PqsR CBD, obtained by molecular docking simulations (see Materials and Methods for details), are shown. The three drugs are represented in red, while the natural ligand NHQ is represented in green.
