disease. Novel 2,6-disubstituted pyridine derivatives were designed to interact with the β-sheet conformation of Aβ via donor–acceptor–donor hydrogen bond formation. A series of pyridine derivatives were synthesized and tested regarding their potential to inhibit the aggregation of Aβ. The 2,6-diaminopyridine moiety was identified as a key component to inhibit Aβ aggregation. Overall, compounds having
据推测,淀粉样β蛋白聚集是阿尔茨海默氏病发病机理中的关键事件。新型2,6-二取代吡啶衍生物经设计可通过供体-受体-供体氢键形成与Aβ的β-折叠构象相互作用。合成了一系列吡啶衍生物,并对其抑制Aβ聚集的潜力进行了测试。2,6-二氨基吡啶部分被鉴定为抑制Aβ聚集的关键成分。总体而言,具有被至少一个C 2-或C 3-接头隔开的三个3,2,6-二取代的吡啶单元的化合物表现出对Aβ聚集的最有效抑制。
