Abstract
The isomers vescalagin and castalagin protect SH-SY5Y cells from Aβ42-mediated death. This is achieved better by vescalagin due to the spatial organization of its OH group at the C1 position of the glycosidic chain, improving its capacity to remodel the secondary structure of toxic Aβ42 oligomers.
