β淀粉样肽的成像及β淀粉样肽的聚集的抑制

Summary

This can serve as a detection or monitor of therapeutic treatment of neurodegenerative disease, especially for Alzheimer's disease. It introduces methods of using carbazole-based fluorophores for labelling, imaging and detecting beta amyloid peptides, oligomers, and fibrils that fluoresce strongly upon binding in vitro or in vivo. Also, using these fluorophores that are non-toxic and able to cross the blood brain barrier is for inhibiting the growth of beta amyloid oligomers and preventing their aggregation upon binding in vitro or in vivo. It could potentially serve as Alzheimer's disease therapeutics and/or preventive agents. These fluorophores can potentially be developed into beta-amyloid peptide-specific MRI contrast agents.

Technology Benefits

Strong fluorescence, high resolution and sensitivity

Technology Application

Detect or Monitor therapeutic treatment of neurodegenerative diseases, e.g. Alzheimer's disease

Detailed Technology Description

It gives new design of functional carbazole-based fluorophores for imaging and inhibition the aggregation of Aβ peptides. The imaging agents that can specifically bind Aβ fibrils and plaques in vitro and in vivo are of paramount importance for studying the pathological events of the disease, disease diagnosis and monitoring of therapeutic treatment.
