Fund Project:

It is very important to develop efficient drugs for the cure of Alzheimer's disease. Here, gold nanoparticle probes were utilized to acquire the ability of 13 kinds of compounds to inhibit the Cu²⁺ induced β-amyloid peptide aggregation. Ten of then were screened as the effective inhibitors. The relationships between the chemical structures and their inhibitory efficiencies were also studied as well. We also used the screened molecules to regulate the morphology changes of Cu²⁺-β-amyloid aggregates and to decrease the production of H₂O₂ formed by the interaction of Cu²⁺ and β-amyloid peptide. This research is significant to the study of Alzheimer's disease.
