  Conversion of iodine to fluorine-18 based on iodinated chalcone and evaluation for β-amyloid PET imaging

  摘要：

  In the amyloid cascade hypothesis, beta-amyloid (A beta) plaques is one of the major pathological biomarkers in the Alzheimer's disease (AD) brain. We report the synthesis and evaluation of novel radiofluorinated chalcones, [F-18] 4-dimethylamino-4'-fluoro-chalcone ([F-18] DMFC) and [F-18] 4'-fluoro-4-methylamino-chalcone ([F-18] FMC), as A beta imaging probes. The conversion of iodine directly introduced to the chalcone backbone into fluorine was successfully carried out by F-18-labeling via the corresponding boronate precursors, achieving the direct introduction of fluorine-18 into the chalcone backbone to prepare [F-18] DMFC and [F-18] FMC. In a biodistribution study using normal mice, [F-18] DMFC and [F-18] FMC showed a higher initial uptake (4.43 and 5.47% ID/g at 2 min postinjection, respectively) into and more rapid clearance (0.52 and 0.66% ID/g at 30 min postinjection, respectively) from the brain than a Food and Drug Administration (FDA)-approved A beta imaging agent ([F-18] Florbetapir), meaning the improvement of the probability of detecting A beta plaques and the reduction of non-specific binding in the brain. In the in vitro binding studies using aggregates of recombinant A beta peptides, [F-18] DMFC and [F-18] FMC showed high binding affinity to recombinant A beta aggregates at the K-d values of 4.47 and 6.50 nM, respectively. In the in vitro autoradiography (ARG) experiment with AD brain sections, [F-18] DMFC and [F-18] FMC markedly accumulated only in a region with abundant A beta plaques, indicating that they clearly recognized human A beta plaques in vitro. These encouraging results suggest that [F-18] DMFC and [F-18] FMC may be promising PET probes for the detection of an amyloid pathology and the early diagnosis of AD with marked accuracy.

  There is provided a composition comprising a compound represented by general formula (I), wherein R l represents a 5-iodothiophen-2-yl group or the like, and R 2 represents a 4-dimethylaminophenyl group or the like. This composition is useful for diagnosis of an amyloid-related disease such as Alzheimer's disease because the compound has high binding specificity to amyloid β protein, high permeability through the blood-brain barrier, and a property of being rapidly eliminated from sites other than senile plaques in the brain.

  This paper describes the synthesis and biological evaluation of fluoro-pegylated (FPEG) chalcones for the imaging of β-amyloid (Aβ) plaques in patients with Alzheimer’s disease (AD). FPEG chalcone derivatives were prepared by the aldol condensation reaction. In binding experiments conducted in vitro using Aβ(1−42) aggregates, the FPEG chalcone derivatives having a dimethylamino group showed higher
