چکیده
The title compound, C(16)H(13)N, is essentially planar [maximum deviation from the least-squares plane = 0.081 (3) Å], with a dihedral angle of 1.65 (13)° between the planes of the indole and benzene rings. In the crystal, there are no significant inter-molecular π-π inter-actions [minimum ring centroid-centroid separation = 4.217 (5) Å].

We report the synthesis and biological evaluation of novel (E)-5-styryl-1H-indole and (E)-6-styrylquinoline derivatives as probes for imaging β-amyloid (Aβ) plaques. These derivatives showed binding affinities for Aβ₁₋₄₀ aggregates with K(i) values varying from 4.1 to 288.4 nM. (E)-5-(4-iodostyryl)-1H-indole (8) clearly stained Aβ plaques in the brain sections of Alzheimer's disease (AD) model ...
