CA 2725897

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 pyrazole derivatives, compositions, and therapeutic uses and processes for making such compounds.

La présente invention concerne de nouveaux composés se liant aux amyloïdes et des procédés de mesure des effets des composés, en mesurant les changements dans le niveau de la plaque amyloïde chez des patients vivants. Plus particulièrement, la présente invention concerne un procédé d'utilisation des composés de l'invention comme traceurs en imagerie par tomographie d'émission de positrons (PET) afin d'étudier les dépôts amyloïdes dans le cerveau in vivo pour permettre le diagnostic de la maladie d'Alzheimer. Ainsi, la présente invention concerne l'utilisation de nouveaux composés se liant aux amyloïdes à des fins diagnostiques. L'invention concerne en outre un procédé de mesure de l'efficacité clinique d'agents thérapeutiques contre la maladie d'Alzheimer. Spécifiquement, la présente invention concerne de nouveaux dérivés pyrazoles substitués par un aryle ou un hétéroaryle, des compositions, et des utilisations thérapeutiques et des procédés pour fabriquer de tels composés.
