) are disclosed. Benzylideneaniline derivatives according to the present invention have high affinity to β-amyloid plaques. Thus, they can cross the blood-brain-barrier (BBB) and bind to β-amyloid plaques after administration into the body, making them useful for treatment, prevention, or imaging of Alzheimer's disease.
