amyloid beta-peptide human

β-淀粉样蛋白(1-42), 人是一种由 42 个氨基酸组成的肽，在阿尔茨海默病的发病机制中起关键作用。

β-Amyloid (1-42), (rat mouse) (TFA) 是由 42 个氨基酸组成的多肽片段，可用于研究阿尔茨海默症。

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.

β-Amyloid (1-16) rat 是β-淀粉样肽 (Abeta) 金属结合域的片段，含有三个与人类相异的氨基酸替代，因此在大鼠和小鼠中降低了 AD 样神经退行性变的易感性。

hAChE-IN-5（化合物49）是一种同时针对hAChE和hBuChE的有效抑制剂，其IC50值均为0.17 μM。此外，hAChE-IN-5对GSK3β同样展现出良好的抑制活性，IC50值为0.21 μM。作为tau蛋白聚集和Aβ1-42自聚集的抑制剂，hAChE-IN-5能够结合PAS，进而阻止Aβ依赖的神经毒性。其能穿透血脑屏障（BBB），显示出成为多靶点抗阿尔茨海默病药物研究的潜力。

β-Amyloid (42-1), human is the inactive form of Amyloid β Peptide (1-42) which plays a key role in the pathogenesis of Alzheimer disease.

Amyloid β Peptide (42-1)(human) acetate 是淀粉样蛋白 β 肽 (1-42) 的无活性形式。Amyloid β Peptide (42-1)(human) acetate 是由 42 个氨基酸组成的肽，其在阿尔茨海默病的发病机制中起关键作用。
