The present invention relates to novel derivatives that are suitable as precursors to compounds that are useful for imaging amyloid deposits in living patients, their compositions, methods of use and processes to make such compounds. The compounds deriving from these precursors are useful in methods of imaging amyloid deposits in brain in vivo to allow antemortem diagnosis of Alzheimer's disease by positron emission tomography (PET) as well as measuring clinical efficacy of Alzheimer's disease therapeutic agents. Furthermore, the present invention also discloses the precursor compounds in crystalline form.
本发明涉及新型衍生物,适用于成为有用于在活体患者中成像淀粉样沉积的化合物的前体,以及它们的组成、使用方法和制造这些化合物的过程。从这些前体衍生的化合物在体内成像淀粉样沉积的方法中非常有用,以允许通过正电子发射断层扫描(PET)进行临床前诊断阿尔茨海默病,并测量阿尔茨海默病治疗药物的临床疗效。此外,本发明还披露了晶体形式的前体化合物。
