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.

Rolipram (Standard)
0 ImagesSynonyms: (R,S)-Rolipram (Standard); (±)-Rolipram (Standard); ZK 62711 (Standard)Rolipram (Standard) is the analytical standard of Rolipram (HY-16900). This product is intended for research and analytical applications. Rolipram is a PDE4 inhibitor, with blood-brain barrier permeability, that reverses β-amyloid-induced learning and memory impairment in rats. Rolipram elevates intracellular cAMP and clevels and regulates the cAMP/CREB signaling pathway, thereby alleviating neuroinflammation and apoptotic responses. Rolipram promotes neuronal differentiation of human bone marrow mesenchymal stem cells and inhibits Methamphetamine- and morphine-induced hyperlocomotion in mice. Rolipram also reduces the viability of glioblastoma stem-like cells and enhances Bevacizumab (HY-P9906)-induced cell death. Rolipram inhibits the expression of proinflammatory cytokines and enhances central noradrenergic transmission. Rolipram is mainly used in studies related to various central nervous system diseases including Alzheimer's disease, major depressive disorder, glioblastoma multiforme, and multiple sclerosis.
