The present invention relates to a method for identifying an inhibitor of the aggregation of amyloid-β peptide (Aβ), comprising the steps of a) contacting at least one Aβ-peptide and/or the nitrated forms thereof with at least one candidate inhibitor that potentially specifically binds to a region in said Aβ-peptide capable of being nitrated, and b) detecting said inhibitor specifically binding to said region in said Aβ-peptide through detecting a lack of or a reduced aggregation of said at least one Aβ-peptide. The present invention is further directed at improved methods for treating neuronal degradation and particularly Alzheimer's disease, based on said inhibitor. The present invention is further directed at methods for diagnosing the aggregation of Aβ-peptide in the context of neuronal degradation and particularly Alzheimer's disease.
本发明涉及一种鉴定淀粉样β肽(Aβ)聚集抑制剂的方法,包括以下步骤 a) 将至少一种Aβ肽和/或其硝化形式与至少一种候选抑制剂接触,所述候选抑制剂可能与所述Aβ肽中能够被硝化的区域特异性结合、b) 通过检测所述至少一种 Aβ 肽的聚集缺乏或聚集减少情况,检测所述抑制剂与所述 Aβ 肽中所述区域的特异性结合情况。本发明进一步涉及基于所述抑制剂治疗神经元退化,特别是阿尔茨海默病的改进方法。本发明进一步涉及在神经元退化,特别是阿尔茨海默病的情况下诊断Aβ肽聚集的方法。
