生化/生理作用
X-34是一种荧光淀粉样特异性染料。 它与Pittsburgh CompoundB的结合位点不同，并且是β-折叠结构的一种高度荧光标记。
X-34（1,4-双（3-羧基-4-羟基苯基乙烯基）-苯）是参与到降低Aβ42水平（淀粉样-β肽的42个残基异构体）的一种小分子γ-分泌酶调节因子（GSM）。X-34还被用于在活的转基因秀丽隐杆线虫体内对具有经典淀粉样纤维超微结构的细胞内免疫反应性沉积物进行可视化。它还可作为组织化学染色剂用于确定阿尔茨海默氏′病（AD）的病理变化。

The pathological finding of amyloid-β (Aβ) aggregates is thought to be a leading cause of untreated Alzheimer's disease (AD). In this study, we isolated 2-butoxytetrahydrofuran (2-BTHF), a small cyclic ether, from Holothuria scabra and demonstrated its therapeutic potential against AD

The most significant genetic risk factor for late-onset Alzheimer's disease (AD) is APOE4, with evidence for gain- and loss-of-function mechanisms. A clinical need remains for therapeutically relevant tools that potently modulate APOE expression. We optimized small interfering RNAs (di-siRNA, GalNAc)

Deposits comprised of amyloid-β (Aβ) are one of the pathological hallmarks of Alzheimer's disease (AD) and small hydrophobic ligands targeting these aggregated species are used clinically for the diagnosis of AD. Herein, we observed that anionic oligothiophenes efficiently displaced X-34
