A composition for diagnosing amyloid-related diseases, which comprises a flavone derivative, a chalcone derivative, a styrylchromone derivative, or a coumarin derivative, is provided. These compounds have high binding specificity to an amyloid β protein, high permeability to a blood-brain barrier, and ability to rapidly disappear from sites other than cerebral senile plaque. Accordingly, the composition of the present invention using these compounds enables the diagnosis of amyloid-related diseases with high precision.
本研究提供了一种用于诊断淀粉样蛋白相关疾病的组合物,该组合物由
黄酮衍
生物、
查尔酮衍
生物、
苯乙烯基
色酮衍
生物或
香豆素衍
生物组成。 这些化合物与淀粉样β蛋白的结合特异性高,对血脑屏障的渗透性高,能够从脑衰老斑块以外的部位迅速消失。 因此,使用这些化合物的本发明组合物能够高精度地诊断淀粉样蛋白相关疾病。
