Semilicoisoflavone B，一种异黄酮，主要来源于 Glycyrrhiza uralensis Fisch.。Semilicoisoflavone B 通过抑制 β-分泌酶-1 (BACE1) 的表达和活性来减少淀粉样蛋白 β (amyloid β，Aβ) 的分泌。Semilicoisoflavone B 主要通过增加 PPARγ 表达和抑制 STAT3 磷酸化来降低 BACE1 的表达。
Semilicoisoflavone B, an isoflavone, mainly derived from Glycyrrhiza uralensis Fisch.. Semilicoisoflavone B reduces amyloid β (Aβ) secretion by inhibiting β-secretase-1 (BACE1) expression and activity. Semilicoisoflavone B decreases BACE1 expression mainly through increasing PPARγ expression and inhibiting STAT3 phosphorylation[1].
