  Structure-Based Design of Highly Selective β-Secretase Inhibitors: Synthesis, Biological Evaluation, and Protein–Ligand X-ray Crystal Structure

  摘要：

  The structure-based design, synthesis, and X-ray structure of protein-ligand complexes of exceptionally potent and selective beta-secretase inhibitors are described. The inhibitors are designed specifically to interact with S-1' active site residues to provide selectivity over memapsin 1 and cathepsin D. Inhibitor 5 has exhibited exceedingly potent inhibitory activity (K-i = 17 pM) and high selectivity over BACE 2 (>7000-fold) and cathepsin D (>250000-fold). A protein ligand crystal structure revealed important molecular insight into these selectivities. These interactions may serve as an important guide to design selectivity over the physiologically important aspartic acid proteases.
