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 pyrazole 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及测量这些化合物效果的方法,通过测量活体患者淀粉样斑块
水平的变化来实现。更具体地说,本发明涉及使用本发明化合物作为追踪剂在正电子发射断层扫描(PET)成像中研究体内脑部淀粉样沉积,以诊断阿尔茨海默病。因此,本发明涉及将新型淀粉样蛋白结合化合物用作诊断工具。本发明还涉及测量阿尔茨海默病治疗药物的临床疗效的方法。具体而言,本发明涉及新型芳基或杂环芳基取代的
