The present invention is directed to isotopically labeled biaryl urea compounds which possess high affinity to neurofibrillary tangles (NFTs), and thus are useful to determine the amount and distribution of NFTs in brain. The isotopically labeled biaryl urea compounds may also be useful as PET tracers and in competition assays to identify other compounds that may serve as PET tracers.
本发明涉及同位素标记的双芳基脲化合物,其具有高亲和力与神经纤维缠结体(NFTs)结合,因此可用于确定大脑中NFTs的数量和分布。同位素标记的双芳基脲化合物也可用作PET示踪剂,并用于竞争试验以鉴定其他可能用作PET示踪剂的化合物。
