Abstract

We evaluated the inhibitory effects of our developed Chol-PEG2000 micelles and Chol-PEG500 vesicles on amyloid-β (Aβ) aggregation, a key factor in Alzheimer's disease. ThT assay proved that Chol-PEG2000 delayed Aβ fibril elongation by 17 hours and Chol-PEG500 by 40 hours at 10-times molar ratio against Aβ40 peptide. At 50-times molar ratio, both Chol-PEG2000 and Chol-PEG500 significantly inhibited Aβ aggregation, as shown by minimal fluorescence intensity increase over 48 hours.
