Molecular dynamics simulations were used to successfully reproduce the experimentally observed pH-dependent conformational behavior of a monomeric peptide in aqueous solution. Simulations were conducted at 298 K on a peptide corresponding to residues 1-28 of the amyloid beta-peptide [referred to

We assessed the neuroprotective capabilities of S12024 (R,S 1-methyl 8-(2-morpholinylmethoxy)-1,2,3,4-tetrahydroquinoleine methane sulphonate) in a model of neuronal degeneration in the dentate gyrus of the rat hippocampus. Specific degeneration of a large part of neurons in the lateral blade of the

beta-amyloid (beta A) deposition is a key event in the etiopathogenesis of Alzheimer's disease (AD), contributing to neuronal degeneration and cognitive impairment in AD patients. Both neurotrophic and neurotoxic actions of beta A have been demonstrated in experimental conditions. In

The neurotoxicity of beta-amyloid protein (beta AP) fragments may be a result of their solution conformation, which is very sensitive to solution conditions. In this work we describe NMR and CD studies of the conformation of beta AP(12-28) in lipid
