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.

    Pellitorine (Standard)
    		Inhibitor
    Pellitorine (Standard) is the analytical standard of Pellitorine (HY-N3097). Pellitorine is a bioactive natural amide compound. Pellitorine can competitively antagonize the activation of TRPV1 by Capsaicin (HY-10448), thereby reducing pain signal transmission. Pellitorine improves cognitive dysfunction by upregulating the BDNF-ERK1/2-CREB and Nrf2-HO-1 pathways. Pellitorine exerts anti-inflammatory and anti-sepsis effects by inhibiting the release of high mobility group protein B1 (HMGB1) and the expression of RAGE/TLR4. Pellitorine exerts its antithrombotic effect by prolonging the clotting time, inhibiting the activity of clotting factors and thrombin. Pellitorine inhibits lipid peroxidation and resists ferroptosis by upregulating GPX4 and DHODH. Pellitorine kills Aedes aegypti mosquito larvae by inhibiting V-type H⁺-ATPase and aquaporin 4 (AaAQP4). Pellitorine exhibits anti-cancer activity (e.g., leukemia and breast cancer) and has inhibitory effects on certain bacteria.
