  Synthesis and Evaluation of ¹⁸F-Labeled Styryltriazole and Resveratrol Derivatives for β-Amyloid Plaque Imaging

  摘要：

  In the present study, a styryltriazole and four resveratrol derivatives were synthesized as candidates for beta-amyloid (A beta) plaque imaging. On the basis of their binding affinities to A beta(1-42) aggregates, the styryltriazole (1, K-i = 12.8 nM) and one resveratrol derivative (5, K-i = 0.49 nM) were labeled with F-18. In normal mice, tissue distribution of [F-18]5 showed good initial brain uptake (3.26% ID/g at 2 min) but slow wash-out from brains (2-to-60 min uptake ratio: 2.9). Furthermore, it underwent in vivo metabolic defluorination (1.88% ID/g at 2 min and 9.73% ID/g at 60 min). In contrast, [F-18]1 displayed high initial brain uptake (5.38% ID/g at 2 min) with rapid wash-out from brains (0.52% ID/g at 60 min; 2-to-60 min uptake ratio: 10.3). These results indicate that [F-18]1 has in vivo kinetics comparable to PET radiopharmaceuticals currently under commercial development, demonstrating that [F-18]1 is a desirable PET radioligand for A beta plaque imaging.
