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.

摘要

二氢芝麻素和芝麻林素异构体可保护 SH-SY5Y 细胞免受 Aβ42 介导的死亡。由于二氢芝麻素 C1 位糖链上的 OH 基团的空间组织,使其能够更好地实现这一点,从而提高其重塑有毒 Aβ42 寡聚物二级结构的能力。
