Zusammenfassung
Ziele: As a promising new approach for the early diagnosis of Alzheimer's disease (AD), we evaluated novel fluorescent probes for the molecular imaging of amyloid-ß (Aß) deposits and fibrillar tau. The aim of our work was to assess their applicability as novel in vivo AD ligands by determining their target affinity and biocompatibility. Methode: The affinity of our novel UV-VIS fluorescent pyrazine and pyrimidine based bisstilbenes and NIR asymmetric hemicyanines to Aß deposits and tau fibrils were determined via histopathological staining of human AD brain slices and semiquantitative analysis of Aß1 – 42-bindin…
