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

Human beta-amyloid protein 42 (1-7) is a bioactive chemical.

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 (1-37) (human) 与阿尔茨海默病的精神状态有潜在关联。

The amyloid β-protein is a 39- to 43-amino acid polypeptide that is the primary constituent of senile plaques and cerebrovascular deposits in Alzheimer's disease and Down's syndrome. Additionally it acts as an inhibitor of the ubiquitin-dependent protein degradation in vitro.

AChE BChE MAO-B-IN-4 是一种 1-茚满酮衍生物，是一种有效的MAO-B 抑制剂，对人MAO-B 的IC50为 0.0359 μM。AChE BChE MAO-B-IN-4 是一种有效的AChE 和BChE 酶抑制剂，对人AChE 和BChE 酶的IC50值分别为 0.0473 μM 和 0.0782 μM。AChE BChE MAO-B-IN-4 显示出显着的抗氧化活性，并防止β-淀粉样蛋白斑块聚集。AChE BChE MAO-B-IN-4 具有用于阿尔茨海默病 (AD) 研究的潜力。

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。
