  Novel BACE1 inhibitors possessing a 5-nitroisophthalic scaffold at the P2 position

  摘要：

  Recently, we reported substrate-based pentapeptidic BACE1 inhibitors possessing a hydroxymethylcarbonyl isostere as a substrate transition-state mimic. These inhibitors showed potent inhibitory activities in enzymatic and cell assays. We also designed and synthesized non-peptidic and small-sized inhibitors possessing a heterocyclic scaffold at the P-2 position. By studying the structure-activity relationship of these inhibitors, we found that the sigma-pi interaction of an inhibitor with the BACE1-Arg235 side chain played a key role in the inhibition mechanism. Hence, we optimized the inhibitors with a focus on their P-2 regions. In this Letter, a series of novel BACE1 inhibitors possessing a 5-nitroisophthalic scaffold at the P-2 position are described along with the results of the related structure-activity relationship study. These small-sized inhibitors are expected improved membrane permeability and bioavailability. (C) 2012 Elsevier Ltd. All rights reserved.

  We have previously reported potent substrate-based pentapeptidic BACE1 inhibitors possessing a hydroxymethylcarbonyl isostere as a substrate transition-state mimic. While these inhibitors exhibited potent activities in enzymatic and cellular assays (KMI-429 in particular inhibited A beta production in vivo), these inhibitors contained some natural amino acids that seemed to be required to improve enzymatic stability in vivo and permeability across the blood-brain barrier, so as to be practical drug. Recently, we synthesized non-peptidic and small-sized BACE1 inhibitors possessing a heterocyclic scaffold at the P-2 position. Herein we report the SAR study of BACE1 inhibitors possessing this heterocyclic scaffold, a chelidonic or 2,6-pyridinedicarboxylic moiety. (C) 2013 Elsevier Ltd. All rights reserved.

  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.
