abstract = {Alzheimer’s disease (AD) is a progressive
neurodegenerative disorder that is associated with the
aggregation of the amyloid β protein (Aβ). Aβ oligomers
are currently thought to be the major neurotoxic agent
responsible for disease development and progression. Thus,
their elimination is highly desirable for therapy
development. Our therapeutic approach aims at specific and
direct elimination of toxic Aβ oligomers by stabilizing Aβ
monomers in an aggregation-incompetent conformation. We have
proven that our lead compound “D3”, an all
d-enantiomeric-peptide, specifically eliminates Aβ
oligomers in vitro. In vivo, D3 enhances cognition and
reduces plaque load in several transgenic AD mouse models.
Here, we performed a large-scale oral proof of concept
efficacy study, in which we directly compared four of the
most promising D3-derivatives in transgenic mice expressing
human amyloid precursor protein with Swedish and London
mutations (APPSL), transgenic mice, to identify the most
effective compound. RD2 and D3D3, both derived from D3 by
rational design, were discovered to be the most effective
derivatives in improving cognition in the Morris water maze.
The performance of RD2- and D3D3-treated mice within the
Morris water maze was significantly better than
placebo-treated mice and, importantly, nearly as good as
those of non-transgenic littermates, suggesting a complete
reversal of the cognitive deficit of APPSL mice.},
