AB  - In peptidotriazolamers every second peptide bond is replaced by a 1H-1,2,3-triazole. Such foldamers are expected to bridge the gap in molecular weight between small-molecule drugs and protein-based drugs. Amyloid beta (Abeta) aggregates play an important role in Alzheimer's disease. We studied the impact of amide bond replacements by 1,4-disubstituted 1H-1,2,3-triazoles on the inhibitory activity of the aggregation "hot spots" K16 LVFF20 and G39 VVIA42 in Abeta(1-42). We found that peptidotriazolamers act as modulators of the Abeta(1-42) oligomerization. Some peptidotriazolamers are able to interfere with the formation of toxic early Abeta oligomers, depending on the position of the triazoles, which is also supported by computational studies. Preliminary in vitro results demonstrate that a highly active peptidotriazolamer is also able to cross the blood-brain-barrier. © 2021 The Authors. ChemPlusChem published by Wiley-VCH GmbH.
