  摘要：

  本文介绍了利用设计的人工配体稳定δ-片材的一般概念。这些配体有两个主要特征：它们含有酰化的 3-氨基吡唑，具有 DAD 氢键供体和受体模式；它们被合成为低聚物，以增加它们与δ-片构象中的肽的氢键相互作用。二聚氨基吡唑可通过 N1-Boc 保护的氨基吡唑衍生物 1 与几种二氯酸反应，然后用三氟乙酸进行标准脱保护处理而获得。对于低聚物，对新的吡唑氨基酸进行 N1-PMB 保护，然后使用 PyClop 或 Mukaiyama 试剂与肽偶联进行迭代扩展，最终得到目标化合物。随后，所有的保护基团都在最后一步用温三氟乙酸进行脱保护。对两个二聚关键化合物 3b 和 3f 进行了不同温度下的核磁共振、NOESY 实验和 X 射线晶体学研究，以阐明它们在溶液和固体状态下的构象偏好。所有方法得出的结果都是一样的：两种配体都采用具有高度预取向性的扁平构象和正确的 DAD 模式，以便与扩展构象中的肽发生最佳相互作用。用朊病毒蛋白和阿尔茨海默氏症肽 Aβ (1-40) 进行的聚合试验表明，一些二聚体和寡聚体配体在极低浓度下就能产生很好的效果。

  The present invention relates to compounds of the general formula (I) wherein (formula 2) independently represents a single bond or a double bond, represents a linking group A and A′ are each independently a 5- to 7-membered heterocyclic ring, wherein the heterocyclic rings A und A′ are optionally substituted by one or more substituents, selected from C 1-6 alkyl, C 3-6 cycloalkyl, optionally substituted phenyl, optionally substituted heteroaryl, C 1-4 alkylene-(optionally substituted phenyl) and C 1-4 alkylene-(optionally substituted heteroaryl), or two substituents may be joined to form an optionally substituted, saturated, unsaturated or aromatic 5- to 7-membered ring which is fused with the heterocyclic ring A or A′, and wherein the heterocyclic rings A und A′ may contain in addition to the units X, X′, Y and Y′ one or more heteroatoms, selected from N, NR, S and Ol wherein R is selected from H and C 1-4 alkyl; the units X and X′ are each independently a H-bond acceptor; and the units Y and Y′ are each independently a H-bond donor. The compound of formula (I) can be employed in the treatment of a group of disorders and abnormalities associated with amyloid protein, such as Alzheimer's disease, and of diseases or conditions associated with amyloid-like proteins. The compounds of the present invention can also be used in the treatment of ocular diseases associated with pathological abnormalities/changes in the tissues of the visual system.

  The invention on hand refers to diseases associated with abnormal protein structures, including Alzheimer's disease, Creutzfeldt-Jakob's disease, BSE and other prion-associated diseases. It is the task of the invention on hand to provide new active agents preventing the formation of amyloid plaques and to dissolve existing plaques, such agents being convenient for therapy, diagnosis and prophylaxis of diseases that are associated with abnormal protein structures. This task is performed in terms of the current invention by heterocyclic or aromatic agents with a rigid structure and a donor-acceptor-donor pattern (DAD), the latter being formed by donors and acceptors of hydrogen bridge linkages which comply with the β-sheet structure of the peptide or protein and thus fit as binding partners. The heterocyclic or aromatic agents are available at least as dimers. They recognise peptides and proteins with a β-sheet structure, form stable complexes with them and inhibit their aggregation to β-amyloid plaques. Furthermore, the new active agents are able to dissolve β-amyloid plaques that already exist. Another task of the current invention is to provide methods for the synthesis of said heterocyclic or aromatic compounds.

  该发明涉及与异常蛋白结构相关的疾病，包括阿尔茨海默病、克雅氏病、疯牛病和其他与朊病毒相关的疾病。该发明的任务是提供新的活性剂，预防淀粉样斑块的形成并溶解现有的斑块，这些活性剂方便用于治疗、诊断和预防与异常蛋白结构相关的疾病。本发明通过具有刚性结构和给受体给体（DAD）模式的杂环或芳香族活性剂来执行此任务，后者由氢桥键的给体和受体组成，符合肽或蛋白的β-片层结构，因此适合作为结合伙伴。这些杂环或芳香族活性剂至少以二聚体的形式存在。它们能够识别具有β-片层结构的肽和蛋白质，与它们形成稳定的复合物并抑制它们聚集成β-淀粉样斑块。此外，这些新的活性剂能够溶解已经存在的β-淀粉样斑块。本发明的另一个任务是提供合成所述杂环或芳香族化合物的方法。
