Abstract

A rationally designed oligomerization inhibitor interacts with early intermediate assemblies of amyloid-beta polypeptide (Abeta) through the aromatic elements and inhibits their assembly into the toxic oligomers that cause Alzheimer's disease by a unique C(alpha)-methylation beta-breakage strategy. The electrostatic potential of the low-energy conformation of the dipeptide inhibitor bound to Abeta is shown.

摘要

一种经过合理设计的寡聚化抑制剂通过芳香族元素与β淀粉样多肽(Aβ)的早期中间聚集体相互作用,并通过独特的α-甲基化β断裂策略抑制其组装成导致阿尔茨海默病的有毒寡聚体。展示了与Aβ结合的二肽抑制剂低能构象的静电势。
