摘要:
Capillary electrophoresis (CE) and ESR spectral measurements have revealed that amyloid beta-peptide ( 1 - 40) interacts with the copper( II)-(dpgt)complex specifically in solution, leading to an aggregation of the Cu( II)- complex, but the analogous copper complex with (dpa-GMe) did not aggregate under the same experimental conditions, where ( dpgt) representsN,N-bis(2-pyridylmethyl) glycylglycylglycine. These facts seem to be very important to elucidate the origin of the abnormal storage of the metal ions such as copper or iron ions in the senile plaques of Alzheimer's disease patients brain tissue.
