Patent

CA 2725934

The present invention relates to novel amyloid binding compounds and methods for measuring effects of the compounds, by measuring changes of amyloid plaque level in living patients. More specifically, the present invention relates to a method of using the compounds of this invention as tracers in positron emission tomography (PET) imaging to study amyloid deposits in brain in vivo to allow diagnosis of Alzheimer's disease. Thus, the present invention relates to use of the novel amyloid binding compounds as a diagnostic. The invention further relates to a method of measuring clinical efficacy of Alzheimer's disease therapeutic agents. Specifically, the present invention relates to novel aryl or heteroaryl substituted indole derivatives, compositions, and therapeutic uses and processes for making such compounds.

L'invention concerne de nouveaux composés de liaison à l'amyloïde et des procédés qui permettent d'évaluer les effets desdits composés en mesurant les changements de niveau de la plaque amyloïde chez des patients en vie. L'invention se rapporte, en particulier, à un procédé selon lequel on utilise les composés précités comme traceurs en imagerie par tomographie à émission de positrons (TEP) afin d'étudier in vivo les dépôts amyloïdes dans le cerveau et de pouvoir poser le diagnostic de la maladie d'Alzheimer. L'invention porte par conséquent sur l'utilisation diagnostique des nouveaux composés de liaison à l'amyloïde. L'invention concerne en outre un procédé qui permet de mesurer l'efficacité clinique d'agents thérapeutiques contre la maladie d'Alzheimer. En particulier, l'invention se rapporte à de nouveaux dérivés indoles substitués par aryle ou hétéroaryle, à des compositions de ces derniers, et à des utilisations thérapeutiques et des procédés de fabrication de ceux-ci.
