amyloid b-protein

β-Amyloid (22-35) is a 14-aa peptide, shows aggregates and induces neurotoxicity in the hippocampal cells. Beta amyloid (22-35) is a synthetic truncated fragment of beta-amyloid peptide.

β-Amyloid (1-28), a fragment of the β-Amyloid protein, is involved in metal binding.

Amyloid β-peptide fragment; minimum section required to bind to brain proteins. Binds with high affinity to α7-nicotinic ACh receptors, and impairs memory retention following central administration in mice in vivo.

β-Amyloid (1-16) is an amyloidogenic protein fragment with a sequence derived from β-amyloid. It exhibits the ability to bind to metal ions, indicating its involvement in metal-binding processes. β-Amyloid, a peptide, is responsible for the formation of amyloid plaques in the brains of individuals affected by Alzheimer's disease (AD).

β-Amyloid (1-15) (Amyloid β-Protein (1-15)) 是 β-淀粉样蛋白片段，可用于研究阿尔茨海默病。

β-Amyloid (29-40), a fragment of the Amyloid-β peptide, possesses physical and chemical properties similar to those of viral protein fusion peptides. The C-terminal fragments (29-40/42) of Alzheimer's beta amyloid peptide can induce the fusion of liposomes.

β-amyloid (12-28) TFA, a peptide fragment of β-amyloid protein (β1-42), is the major component of senile plaque cores. β-amyloid (12-28) has aggregation properties and the potential for Alzheimer's disease research.

Amyloid β-Protein (10-20) is a fragment of Amyloid-β peptide, maybe used in the research of neurological disease.Amyloid β protein fragment containing the α-secretase processing site (Lys16-Leu17 bond). It also contains the HHQK domain (residues 13-16) re

Amyloid β-Protein 10-20 acetate (Amyloid β-Protein 10-20 acetate (152286-31-2 free base)) 是 Amyloid-β 肽的片段，可能用于神经系统疾病的研究。Amyloid β 蛋白片段含有 α-分泌酶加工位点（Lys16-Leu17 键）。它还包含负责与小胶质细胞结合的 HHQK 结构域（残基 13-16）。

Multitarget AD inhibitor-2 (Compound VN-19) 是一种多靶点抑制剂，对乙酰胆碱酯酶 (AChE, IC50=0.14 μM)，丁酰胆碱酯酶 (BChE, IC50=11.6 μM)，以及单胺氧化酶B (MAO B, IC50=0.45 μM) 有效。Multitarget AD inhibitor-2 能够抑制淀粉样 β 蛋白 Aβ1-42 的自诱导聚集 (在20 μM时抑制率达47.3%)，并降低 SH-SY5Y 细胞中的 ROS 水平 (25 μM时抑制率80%)。此外，它能改善Scopolamine引起的阿尔茨海默病斑马鱼模型中的认知能力下降。

MAO-B-IN-45 是一种专门针对铁死亡 (ferroptosis) 和 MAO-B 的双重抑制剂。它对 MAO-B 的选择性显著，IC50 为 87.47 nM，高于 MAO-A 229 倍。MAO-B-IN-45 在体外通过对铁代谢途径和 GSH-GPX4 轴的调控，展现出强大的抗铁死亡活性。此外，MAO-B-IN-45 能改善 3×Tg (APP/Tau/Ps1) 阿尔茨海默病小鼠的认知与行为障碍，并显著降低其脑内铁蛋白重链 1 (FTH1)、β-淀粉样蛋白 (APP) 和 Tau 蛋白磷酸化 (p-Tau) 的水平。

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

Rasagiline-13C3 (mesylate) is intended for use as an internal standard for the quantification of rasagiline by GC- or LC-MS. Rasagiline is an inhibitor of monoamine oxidase B (MAO-B; IC50= 4.43 nM for the rat brain enzyme).1It is selective for MAO-B over MAO-A (IC50= 412 nM for the rat brain enzyme). It inhibits serum and NGF withdrawal-induced apoptosis of PC12 cells when used at concentrations ranging from 0.01 to 100 μM.2Rasagiline inhibits rat brain MAO-Bin vivo (ED50= 0.1 mg/kg).1It reduces cerebral edema in a mouse model of traumatic brain injury.2Rasagiline (0.1 mg/kg)reduces cortical and hippocampal levels of full-length and soluble amyloid precursor protein (APP)in rats and mice. It also reduces α-synuclein-induced substantia nigral neuron loss and improves motor dysfunction in a mouse model of Parkinson's disease.3Formulations containing rasagiline have been used in the treatment of Parkinson's disease.

δ-secretase inhibitor 11是一种分泌酶抑制剂，可用作 阿尔茨海默病（AD） 治疗转化开发的先导化合物。
