A series of Schiff Bases of Ni(II) and Cu(II) using acetylacetone (acac), salicylaldehyde (sal), ethylenediamine (en), and o-phenylendiarnine (dabe) were prepared and characterized. The electronic spectra of some copper chelates in various organic solvents depend strongly on the solvent used and the d-d band of Cu(II) shifts to red with the increase of the Donor Number (DN) of solvent. The ...

Aggregation and subsequent conformational change of Alzheimer’s β-amyloid protein (AβP) enhance its neurotoxicity. Therefore, factors that inhibit or promote conformational changes of AβP play crucial roles in the pathogenesis of Alzheimer’s disease (AD). Moreover, recent studies have suggested that a common mechanism is based on the diverse diseases termed “conformational diseases” including n...
