Thus, Aβ oligomers are a prominent target in AD drug development. Previously, we reported on our solely D-enantiomeric peptide D3 and its derivatives as AD drug candidates. Here, we compare one of the most promising D3 derivatives, ANK6, with its tandem version (tANK6), and its head-to-tail cyclized isoform (cANK6r). In vitro tests investigating the D-peptides’ potencies to inhibit Aβ aggregation, eliminate Aβ oligomers, and reduce Aβ-induced cytotoxicity revealed that all three D-peptides efficiently target Aβ. Subsequent preclinical pharmacokinetic studies of the three all-D-peptides in wildtype mice showed promising blood-brain barrier permeability with cANK6r yielding the highest levels in brain. The peptides’ potencies to lower Aβ toxicity and their remarkable brain/plasma ratios make them promising AD drug candidates. 000848233 536__ $$0G:(DE-HGF)POF3-553$$a553 - Physical Basis of Diseases (POF3-553)$$cPOF3-553$$fPOF III$$x0 000848233 588__ $$aDataset connected to CrossRef 000848233 7001_ $$0P:(DE-Juel1)165908$$aSchemmert, Sarah$$b1$$ufzj 000848233 7001_ $$0P:(DE-Juel1)173023$$aNiemietz, Nicole$$b2$$ufzj 000848233 7001_ $$0P:(DE-Juel1)164541$$aHonold, Dominik$$b3$$ufzj 000848233 7001_ $$0P:(DE-Juel1)162487$$aZiehm, Tamar$$b4$$ufzj 000848233 7001_ $$0P:(DE-Juel1)131709$$aTusche, Markus$$b5$$ufzj 000848233 7001_ $$0P:(DE-Juel1)164354$$aElfgen, Anne$$b6$$ufzj 000848233 7001_ $$0P:(DE-Juel1)171922$$aGering, Ian$$b7$$ufzj 000848233 7001_ $$0P:(DE-HGF)0$$aBrener, Oleksandr$$b8 000848233 7001_ $$0P:(DE-Juel1)131794$$aShah, Nadim Joni$$b9$$ufzj 000848233 7001_ $$0P:(DE-Juel1)131777$$aLangen, Karl-Josef$$b10$$ufzj 000848233 7001_ $$0P:(DE-Juel1)159137$$aKutzsche, Janine$$b11$$ufzj 000848233 7001_ $$0P:(DE-Juel1)132029$$aWillbold, Dieter$$b12$$eCorresponding author$$ufzj 000848233 7001_ $$0P:(DE-Juel1)144347$$aWilluweit, Antje$$b13$$eCorresponding author$$ufzj 000848233 773__ $$0PERI:(DE-600)2070772-1$$a10.3233/JAD-180165$$gVol. 64, no. 3, p. 859 -
