Abstract

In the present study, a styryltriazole and four resveratrol derivatives were synthesized as candidates for β-amyloid (Aβ) plaque imaging. On the basis of their binding affinities to Aβ (1– 42) aggregates, the styryltriazole (1, K i= 12.8 nM) and one resveratrol derivative (5, K i= 0.49 nM) were labeled with 18F. In normal mice, tissue distribution of [18F] 5 showed good initial brain uptake (3.26% ID/g at 2 min) but slow wash-out from brains (2-to-60 min ...
