Abstract: We describe structure-based design, synthesis, and biological evaluation of a series of novel inhibitors bearing a pyrazole (compounds 3a-h) or a thiazole moiety (compounds 4a-e) as the P3 ligand. We have also explored Boc-β-amino-l-alanine as a novel P2 ligand. A number of inhibitors have displayed β-secretase inhibitory potency. Inhibitor 4c has shown potent BACE1 inhibitory activity, Ki=0.25nM, cellular EC50 of 194nM, and displayed good selectivity over BACE2. A model of 4c was created based upon the X-ray structure of 2-bound β-secretase which revealed critical interactions in the active site.
