Aducanumab (BIIB037)，一种选择性人免疫球蛋白γ-1（IgG1）单克隆抗体，靶向β淀粉样蛋白 (Aβ) 的聚集形式。Aducanumab 显示出脑渗透性，可用于治疗阿尔茨海默病 (AD) 。

Umibecestat 是一种β-位点淀粉样前体蛋白裂解酶-1 (BACE-1) 抑制剂，对人 BACE-1 和小鼠 BACE-1 的 IC50 分别为 11 nM 和 10 nM，可用于阿尔茨海默病的研究。

Flutafuranol, also known as AZD 4694 and NAV4694, is a bio-active chemical. AZD4694 shows high affinity for beta-amyloid fibrils in vitro (K(d) = 2.3 + - 0.3 nM). The fluorine-18 labeled AZD4694 may have potential for PET-visualization of cerebral beta-am

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.

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-6（化合物51）是一种能够穿透血脑屏障的AChE抑制剂，具有0.16 μM的IC50。该化合物同时对hBuChE与GSK3β显示出抑制活性，其IC50分别为0.69 μM和0.26 μM。hAChE-IN-6亦能抑制tau蛋白与Aβ1-42的自聚集，适用于阿尔茨海默病（AD）的相关研究。

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。

Anti-Amyloid Beta Antibody (scFv59) 是一种在 CHO 细胞中表达的人源抗体，专门靶向Amyloid-β。其同型对照可参考 Human IgG1 kappa, Isotype Control。

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。
