The present invention relates to novel amyloid binding compounds and methods for measuring effects of the compounds, by measuring changes of amyloid plaque level in living patients. More specifically, the present invention relates to a method of using the compounds of this invention as tracers in positron emission tomography (PET) imaging to study amyloid deposits in brain in vivo to allow diagnosis of Alzheimer's disease. Thus, the present invention relates to use of the novel amyloid binding compounds as a diagnostic. The invention further relates to a method of measuring clinical efficacy of Alzheimer's disease therapeutic agents. Specifically, the present invention relates to novel aryl or heteroaryl substituted indole derivatives, compositions, and therapeutic uses and processes for making such compounds.
本发明涉及新型淀粉样蛋白结合化合物和测量这些化合物效果的方法,通过测量活体患者中淀粉样斑块水平的变化。更具体地说,本发明涉及一种使用该发明化合物作为示踪剂的方法,用于正电子发射断层扫描(PET)成像研究大脑中的淀粉样沉积,以便诊断阿尔茨海默病。因此,本发明涉及将新型淀粉样蛋白结合化合物用作诊断的用途。该发明还涉及一种测量阿尔茨海默病治疗药物临床疗效的方法。具体而言,本发明涉及新型芳基或杂环芳基取代的吲哚衍生物、组合物和治疗用途,以及制备这类化合物的过程。
