All aurone derivatives had sufficient radioactivity to image brain amyloid, and transferred to the brain from the beginning of administration (1.7_4.6% ID / g).

The radioactivity was 2-8% of the radioactivity remaining 2 minutes after administration. From these results, when the aurone derivative was applied to Alzheimer's disease model mice or Alzheimer's disease patients, it showed high binding to the amyloid deposition site, but rapidly lost radioactivity from the normal site in the Alzheimer's disease brain.
