a Three-dimensional representation of best possible poses of ligand molecules (green, stick) inside the binding pocket of β-secretase (black, ribbon). b Two-dimensional representation of ligand–receptor interaction. Interacting amino acids are represented in a three-letter code and their respective number in specific chain inside disc. Dotted lines represent type of interactions; green: conventional hydrogen bond; light green: carbon hydrogen bond. Pink: Pi–Pi stacked and Pi–Pi T-shaped
