  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.

These were used to optimize the potency and selectivity of inhibitors. A systematic structure-activity relationship study led to the identification of determinants of the inhibitors' potency and selectivity toward the BACE2 enzyme.
