A non-toxic Hsp90 inhibitor protects neurons from Abeta-induced toxicity.
The molecular chaperones have been implicated in numerous neurodegenerative disorders in which the defining pathology is misfolded proteins and the accumulation of protein aggregates. In Alzheimer's… Expand

Neuroprotective activity and evaluation of Hsp90 inhibitors in an immortalized neuronal cell line.
Alzheimer's disease (AD) neuropathology is characterized by loss of synapses and neurons, neuritic plaques consisting of beta-amyloid (Abeta) peptides, and neurofibrillary tangles consisting of… Expand

TCP-FA4: a derivative of tranylcypromine showing improved blood-brain permeability.
A variety of approaches have been taken to improve the brain penetration of pharmaceutical agents. The amphipathic character of a compound can improve its interaction with the lipid bilayer within… Expand

β-Amyloid-Induced Neurodegeneration and Protection by Structurally Diverse Microtubule-Stabilizing Agents
Deposition of β-amyloid peptide (Aβ) and hyperphosphorylation of the τ protein are associated with neuronal dysfunction and cell death in Alzheimer's disease. Although the relationship between these… Expand

Therapeutic role of quercetin on oxidative damage induced by acrylamide in rat brain
Abstract Context Quercetin (QE), a bioflavonoid present abundantly in fruits and vegetables, has been reported to possess antioxidant properties. Acrylamide (ACR) is formed in foods during cooking… Expand

p35/Cyclin-dependent kinase 5 is required for protection against β-amyloid-induced cell death but not tau phosphorylation by ceramide
Ceramide is a bioactive sphingolipid, that can prevent calpain activation and β-amyloid (Aß) neurotoxicity in cortical neurons. Recent evidence supports Aß induction of a calpain-dependent cleavage… Expand

Effect of rutin on proinflammatory cytokines and oxidative stress in toxin-mediated hepatotoxicity
Abstract The present study was designed to evaluate the effect of rutin (RT) on lead (Pb)-induced oxidative stress. Rats were divided into groups and were treated with RT with or without lead. Levels… Expand
