Protective effects of Nitraria retusa extract and its constituent isorhamnetin against amyloid β-induced cytotoxicity and amyloid β aggregation

Biosci Biotechnol Biochem. 2015;79(9):1548-51. doi: 10.1080/09168451.2015.1027655. Epub 2015 May 12.

Abstract

Nitraria retusa is a halophyte species that is distributed in North Africa and used as a traditional medicinal plant. In this study, N. retusa ethanol extract and its constituent isorhamnetin (IRA) protected against amyloid β (Aβ)-induced cytotoxicity in human neuroblastoma SH-SY5Y cells. An in vitro Aβ aggregation assay suggested that IRA destabilizes Aβ fibrils.

Keywords: Alzheimer’s disease; amyloid β; isorhamnetin.
