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.

Amyloid β-Protein (3-42)
0 ImagesCat. No.: HY-P4886CAS No.: 157884-74-7Amyloid β-Protein (3-42) is the precursor of Pyr peptide. Pyroglutamate-modified Aβ (pEAβ) (3-42) is the core of the amyloid template block in Alzheimer's disease. pEAβ(3-42) accelerated the aggregation of Aβ(1-42), while Aβ(1-42) significantly slowed the primary and secondary nucleation of pEAβ(3-42).

RI-OR2-TAT
0 ImagesCat. No.: HY-P10824CAS No.: 1430219-69-4RI-OR2-TAT is a brain-penetrant inhibitor of β-Amyloid oligomerization, which is produced by adding the HIV protein transduction domain TAT to RI-OR2. RI-OR2-TAT binds to Aβ42 fibrils with a Kd value of 58-125 nM. RI-OR2-TAT reduces Aβ aggregation and plaque levels, reduces activation of microglia and oxidative damage, and increases the number of young neurons in the dentate gyrus.

Liensinine perchlorate
0 ImagesLiensinine perchlorate is a bisbenzylisoquinoline alkaloid. By inhibiting the PI3K/AKT and JNK/p38-MAPK signaling pathways, Liensinine perchlorate suppresses autophagy and apoptosis, clears Aβ, and exerts anti-inflammatory, antioxidant and neuroprotective effects. Liensinine perchlorate activates AMPK and inhibits the expression of HIF-1α and VEGF, thereby suppressing angiogenesis. Liensinine perchlorate exerts anti-tumor effects through ROS-mediated inhibition of the JAK2/STAT3 signaling pathway. Liensinine perchlorate can be used for the research of diseases such as Alzheimer's disease, hepatocellular carcinoma, osteosarcoma, sepsis-induced organ injury and stroke.
