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.

KMS88009
0 ImagesCat. No.: HY-118243CAS No.: 1089681-42-4KMS88009 is a potent small molecule that directly interferes with the formation of amyloid-β oligomers, thereby preserving cognitive behavior when used preventively and reversing cognitive behavior decline when used therapeutically. Oral administration of KMS88009 around the onset of Alzheimer's disease symptoms significantly reduced the assembly of amyloid-β oligomers and improved cognitive behavior in the APP/PS1 double transgenic mouse model. This unique dual mode of action suggests that KMS88009 may be a powerful therapeutic candidate for the treatment of Alzheimer's disease. In an evaluation, the physicochemical properties, pharmacokinetics and toxicity of this anti-amyloidogenic small molecule KMS88009 were studied, as well as post-mortem analysis of APP/PS1 TG mice after behavioral testing.
