Alzheimer?s disease (AD) is associated with conformational changes of amyloid-? peptides, which result in peptide oligomerization and fibril formation and, finally, in the appearance of senile plaques and extensive neuronal loss. However, the factors regulating the process of plaque-associated beta-amyloid peptide (A?) aggregation are only partly understood. Therefore, several ?-amyloid peptide fragments have been synthesized by SPPS according to Boc/Bzl strategy. Binding of metal ions to ?-amyloid peptides was st...
