  Potent human glutaminyl cyclase inhibitors as potential anti-Alzheimer’s agents: Structure-activity relationship study of Arg-mimetic region

  摘要：

  Pyroglutamate-modified amyloid beta peptides (pGlu-A beta) are highly neurotoxic and promote the formation of amyloid plaques. The pGlu-A beta peptides are generated by glutaminyl cyclase (QC), and recent clinical studies indicate that QC represents an alternative therapeutic target to treat Alzheimer's disease (AD). We have previously developed a series of QC inhibitors with an extended pharmacophoric scaffold, termed the Arg-mimetic D-region. In the present study, we focused on the structure activity relationship (SAR) of analogues with modifications in the D-region and evaluated their biological activity. Most compounds in this series exhibited potent activity in vitro, and our SAR analysis and the molecular docking studies identified compound 202 as a potential candidate because it forms an additional hydrophobic interaction in the hQC active site. Overall, our study provides valuable insights into the Arg-mimetic pharmacophore that will guide the design of novel QC inhibitors as potential treatments for AD. (C) 2018 Elsevier Ltd.
