| Description | Licoflavone A is a natural product isolated from the roots of Glycyrrhiza uralensis. |
| In vitro | 从甘草(Glycyrrhiza uralensis)根部分离出两种新的2-芳基苯并呋喃化合物,分别为glycybenzofuran(1)和cyclolicocoumarone(2),以及10种已知的类黄酮,包括licocoumarone(3)、glycyrrhisoflavone(4)、glisoflavone(5)、cycloglycyrrhisoflavone(6)、isoliquiritigenin(7)、Licoflavone A(8)、apigenin(9)、isokaempferide(10)、glycycoumarin(11)和isoglycycoumarin(12)。这些化合物的结构通过广泛的光谱分析确定。化合物1和5在体外显示出显著的蛋白酪氨酸磷酸酶-1B(PTP1B)抑制活性,其IC50值分别为25.5 μM和27.9 μM。 |
