摘要:
The present invention relates to a phenyl benzyl ether derivative, a preparation method thereof and application of the phenyl benzyl ether derivative to the preparation of medicine for diagnosing and treating the Alzheimer's disease (AD), wherein part of compounds, after being labeled by radionuclide, of the phenyl benzyl ether derivative, are used as Aβ plaque imaging agent. The structural formula of the phenyl benzyl ether derivative is shown by formula (I). The present invention develops a kind of brand new phenyl benzyl ether derivative which has high affinity with Aβ plaques in brains of AD patients. The chemical structure of the phenyl benzyl ether derivative is different from that of compounds disclosed in the prior art and the phenyl benzyl ether derivative belongs to a brand new compound for diagnosing and treating AD. The obtained Aβ plaque imaging agent has the advantages that the in-vivo stability is good, the fat solubility is low, the removal speed for the brain is fast, the problem of removing the radionuclide in vivo does not exist, and the application prospect and the market value are great.
摘要:
The invention concerns novel bi-aromatic compounds of general formula (I) and the method for preparing them, and their use in pharmaceutical compositions for use in human or veterinary medicine (in dermatology, in cancerology, and in the field of autoimmune diseases and that of organ or tissue transplants in particular), or further still in cosmetic compositions.
摘要:
A diaminobenzene derivative represented by the formula (1): wherein X 1 is a bivalent organic group selected from -OCH 2 -, -CH 2 O-, -COOCH 2 - and -CH 2 OOC-, X 2 is -O-, and X 3 is an alkyl or fluoroalkyl group having from 1 to 22 carbon atoms, or a cyclic substituent selected from aromatic rings, aliphatic rings, heterocyclic rings and their substituted groups; a polyimide precursor and a polyimide synthesized by using the diaminobenzene derivative as a part of the material; and a treating agent for liquid crystal alignment containing the polyimide precursor and/or the polyimide.
