β-Amyloid (1-42), human, HFIP-treated, a 42-amino acid peptide that has been treated with HFIP from β-Amyloid (1-42), human (HY-P1363A), is a brain-penetrant amyloid protein fragment, which can be used in research on Alzheimer's disease and Down’s syndrome. β-Amyloid (1-42), human, HFIP-treated remaining as a monomer exhibits antioxidant and neuroprotective effects. β-Amyloid (1-42), human, HFIP-treated, after being dissolved in DMSO to form the stock solution, on the one hand, can form soluble oligomers (AβOs) when incubated at 4°C, which have synaptic toxicity and neurotoxicity; on the other hand, it can be incubated at 37°C to form insoluble fibrils, with lower neurotoxicity, and participating in the oxidative damage process. Aβ42 oligomers bind to various neuronal surface receptors (such as PrPc, mGluR5, NMDA receptors, etc.), triggering oxidative stress, calcium homeostasis imbalance, and synaptic toxicity via activating downstream signaling pathways, leading to neuronal dysfunction and death .

Cat. No.: HY-16900
CAS No.: 61413-54-5
Synonyms: (R,S)-Rolipram; (±)-Rolipram; ZK 62711
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 .

CAS No.: 864167-45-3
Purity:  ≥98.0%
Succinyl phosphonate trisodium salt is a α-Ketoglutarate Dehydrogenase Complex (KGDHC) modulator with neuroprotective activity. Succinyl phosphonate trisodium salt protects this complex, reduces cellular succinyl-CoA concentration, downregulates protein succinylation levels, and inhibits the activity of the α-ketoglutarate dehydrogenase complex. Succinyl phosphonate trisodium salt corrects hypoxic or ethanol-induced behavioral impairments, modulates exploratory behavior and emotional stress responses, and improves hypoxia tolerance. Succinyl phosphonate trisodium salt reduces glutamate excitotoxicity, restores the activity of the α-ketoglutarate dehydrogenase complex, reverses the changes in glutamate dehydrogenase and glutamine synthetase activities induced by β-amyloid (Amyloid-β), modulates cognitive function, and prevents β-amyloid-induced neuronal damage. Succinyl phosphonate trisodium salt improves microglial senescence, alleviates neuroinflammation, reactive oxygen species (ROS) production, lipid peroxidation, and the expression of proinflammatory cytokines. Succinyl phosphonate trisodium salt can be used in the research of Alzheimer's disease, aging-related neuroinflammation, and Parkinson's disease .

Carbenoxolone is a blood-brain barrier-permeable Pannexin1 inhibitor, gap junction (Gap junction) blocker, and β-amyloid 42 inhibitor. Carbenoxolone modulates voltage-gated currents of wild-type and mutant Panx1, and inhibits stimulus-activated Panx1 channel function. Carbenoxolone interacts with stable residues of β-amyloid 42 peptides, fibrils and oligomers, thereby inhibiting their aggregation. Carbenoxolone alleviates liver fibrosis. Carbenoxolone exerts neuroprotective and nootropic effects. Carbenoxolone can be used in studies related to Alzheimer's disease and liver fibrosis .
