abstract = {Alzheimer's disease (AD) is a devastating disease affecting
predominantly the aging population. One of the
characteristic pathological hallmarks of AD are neuritic
plaques, consisting of amyloid-β peptide (Aβ). While there
has been some advancement in diagnostic classification of AD
patients according to their clinical severity, no fully
reliable method for pre-symptomatic diagnosis of AD is
available. To enable such early diagnosis, which will allow
the initiation of treatments early in the disease progress,
neuroimaging tools are under development, making use of
Aβ-binding ligands that can visualize amyloid plaques in
the living brain. Here we investigate the properties of a
newly designed series of D-enantiomeric peptides which are
derivatives of ACI-80, formerly called D1, which was
developed to specifically bind aggregated Aβ1-42. We
describe ACI-80 derivatives with increased stability and Aβ
binding properties, which were characterized using surface
plasmon resonance and enzyme-linked immunosorbent assays.
The specific interactions of the lead compounds with amyloid
plaques were validated by ex vivo immunochemistry in
transgenic mouse models of AD. The novel compounds showed
increased binding affinity and are promising candidates for
further development into in vivo imaging compounds.},
