Fustinis ((±)-Fustin; 3,7,3',4'-Tetrahydroxyflavanone) 是一种有效的淀粉样 β (Aβ) 抑制剂。Fustinis ((±)-Fustin; 3,7,3',4'-Tetrahydroxyflavanone) 可增加 Aβ (1-42) 诱导的乙酰胆碱 (ACh) 水平、胆碱乙酰转移酶 (ChAT) 活性和 ChAT 基因的表达。Fustinis ((±)-Fustin; 3,7,3',4'-Tetrahydroxyflavanone) 降低 Aβ (1-42) 诱导的乙酰胆碱酯酶 (AChE) 活性和 AChE 基因表达。Fustinis ((±)-Fustin; 3,7,3',4'-Tetrahydroxyflavanone) 增加毒蕈碱 M1 受体基因表达和毒蕈碱 M1 受体结合活性。Fustinis ((±)-Fustin; 3,7,3',4'-Tetrahydroxyflavanone) 可用于阿尔茨海默氏病研究。
| 生物活性 | Fustinis ((±)-Fustin; 3,7,3',4'-Tetrahydroxyflavanone) is a potentamyloid 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 acetylcholinesterase(AChE) activity andAChEgene 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. Fustinis ((±)-Fustin; 3,7,3',4'-Tetrahydroxyflavanone) can be used for Alzheimer's disease research[1]. |
