CURCUMIN DERIVATIVES FOR AMYLOID-ß PLAQUE IMAGING

摘要

The present invention provides curcumin-derived near infrared (NIR) imaging probes. Upon interacting with amyloid ß aggregates, these probes undergo a range of changes, qualifying them as "smart" probes. The inventors have demonstrated that probes of the invention have the capacity to monitor the progression of Alzheimer's disease in an in vivo animal model. In addition, the present invention encompasses probes useful as PET imaging agents, MRI imaging agents and multimodal imaging agents, as well as related methods of detecting and imaging amyloid ß aggregates and plaques.
