Overview

Fustinis ((±)-Fustin; 3,7,3',4'-Tetrahydroxyflavanone) is a potent amyloid β (Aβ) inhibitor. Fustinis ((±)-Fustin; 3,7,3',4'-Tetrahydroxyflavanone) increases the expression of acetylcholine (ACh) levels, choline acetyltransferase (ChAT) activity, and ChAT gene induced by Aβ (1-42). Fustinis ((±)-Fustin; 3,7,3',4'-Tetrahydroxyflavanone) decreases in acetyl cholinesterase (AChE) activity and AChE gene expression induced by Aβ (1-42). Fustinis ((±)-Fustin; 3,7,3',4'-Tetrahydroxyflavanone) increases muscarinic M1 receptor gene expression and muscarinic M1 receptor binding activity.
