Molecular docking studies of the compounds with cellular prion protein (PrP^C). Key residues (cyan sticks) involved in the ligand-protein interactions are shown as stick model and H-bonds are indicated by red dashed lines. The protein surface is colored in light gray and BMD42-29 (A), BMD42-2910 (B), and BMD42-2904 (C) are shown as green, yellow, and magenta sticks, respectively. Images were drawn with PyMol (Delano Scientific LLC, San Carlos, CA, USA).
