  Novel non-peptidic and small-sized BACE1 inhibitors

  摘要：

  Recently, we reported substrate-based beta-secretase (BACE1) inhibitors with a hydroxymethylcarbonyl (HMC) isostere as a substrate transition-state mimic. These inhibitors showed potent BACE1 inhibitory activities (similar to 1.2 nM IC50). In order to improve in vivo enzymatic stability and permeability across the blood-brain barrier, these penta-peptidic inhibitors would need to be further optimized. On the other hand, non-peptidic inhibitors possessing isophthalic residue at the P-2 position were reported from other research groups. We selected isophthalic-type aromatic residues at the P-2 position and an HMC isostere at the P-1 position as lead compounds. On the basis of the design approach focused on the conformer of docked inhibitor in BACE1, we found novel non-peptidic and small-sized BACE1 inhibitors possessing a 2,6-pyridinedicarboxylic, chelidamic or chelidonic residue at the P2 position.
