Amyloid-β
β-amyloid peptide; Aβ; Abeta
Amyloid-β (Aβ) denotes peptides of 36–43 amino acids that are crucially involved in Alzheimer's disease as the main component of theamyloid plaques found in the brains of Alzheimer patients. The peptides result from the amyloid precursor protein (APP), which is being cut by certain enzymes to yield Aβ. Amyloid-β molecules can aggregate to form flexible soluble oligomers which may exist in several forms. Amyloid-β peptide is due to overproduction of Aβ and/or the failure of clearance mechanisms. Amyloid-β self-aggregates into oligomers, which can be of various sizes, and forms diffuse and neuritic plaques in the parenchyma and blood vessels. Amyloid-β oligomers and plaques are potent synaptotoxins, block proteasome function, inhibit mitochondrial activity, alter intracellular Ca2+levels and stimulate inflammatory processes. Loss of the normal physiological functions of Aβ is also thought to contribute to neuronal dysfunction.

Scyllo-Inositol (Standard)
0 ImagesScyllo-Inositol is an inhibitor that targets the aggregation of misfolded proteins (such as α-synuclein and Amyloid-β), is orally effective, and can cross the blood-brain barrier. Scyllo-Inositol can selectively bind to and stabilize non-toxic oligomers, preventing them from converting into toxic fibers, exerting protein homeostasis regulation and neuroprotective activity. Scyllo-Inositol binds to the hydrophobic region of pathogenic proteins, inhibits protein aggregation, and promotes lysosome- and proteasome-mediated degradation pathways, thereby reducing neurotoxicity. Scyllo-Inositol can be used in the study of neurodegenerative diseases such as Parkinson's disease, Alzheimer's disease, and Huntington's disease.
