2-arylbenzothiophene derivatives or pharmaceutically acceptable salts thereof, a preparation method thereof, and a pharmaceutical composition for the diagnosis or treatment of degenerative brain disease containing the same as an active ingredient. Since the 2-arylbenzothiophene derivatives of Formula 1 have a relatively high binding affinity for β-amyloid, they can be used as diagnostic reagents for diagnosing Alzheimer's disease at an early stage by non-invasive techniques when they are labeled with radioisotopes:

, V, W, X, Y and Z are as defined in the Detailed Descript of the specification. Further, when the pharmaceutical composition containing the 2-arylbenzothiophene derivative binds with a low-molecular weight β-amyloid peptide binding compound, generation of malignant high-molecular weight β-amyloid deposits is minimized. Accordingly, the pharmaceutical composition can be used as a therapeutic agent of degenerative brain disease such as Alzheimer's disease.
2-芳基苯并噻吩衍生物或其药用可接受盐,其制备方法,以及包含其作为活性成分的用于诊断或治疗退行性脑疾病的药物组合物。由于式1中的2-芳基苯并噻吩衍生物具有相对较高的β-淀粉样蛋白结合亲和力,因此当它们与放射性同位素标记时,它们可以作为诊断试剂用于通过非侵入性技术早期诊断阿尔茨海默病:
其中R1-R4,V,W,X,Y和Z如规范的详细描述中所定义。此外,当含有2-芳基苯并噻吩衍生物的药物组合物与低分子量β-淀粉样蛋白结合化合物结合时,最小化了恶性高分子量β-淀粉样蛋白沉积物的生成。因此,该药物组合物可用作治疗阿尔茨海默病等退行性脑疾病的治疗剂。
