thioflavin t

Amyloid-β (25-35) (Aβ (25-35)) is an 11-residue fragment of the Aβ protein that retains the physical and biological characteristics of the full length peptide. It forms fibrils that react to thioflavin T and Congo red and are organized in a cross-β arrangement of β-strands similar to Aβ (1-40) and Aβ (1-42) fibrils. Aggregated Aβ (25-35) decreases the viability of rat adrenal PC12 cells. It also decreases the viability of primary rat cortical neurons at concentrations ranging from 1 nM to 30 μM. In vivo, intracerebral injection of Aβ (25-35) (20 nmol) in rats induces lesions of neuronal and tissue loss. Aggregated Aβ (25-35) administered intracerebroventricularly to rats induces learning and memory impairments in the Y-maze, novel object recognition, and contextual fear conditioning tests.

BTA-1 是一种不带电的硫代黄素-T 衍生物。BTA-1 对 Aβ 原纤维具有高亲和力，并具有良好的脑进入和清除能力。

Aβ tau aggregation-IN-3为一种高效的抗Aβ聚集剂，经Aβ-硫黄素T (Aβ-ThT) 聚集测定显示，其半抑制浓度(IC50)为0.85 μM，表现出显著的抗淀粉样蛋白活性。
