甘草提取物(甘草FISHER,豆科)显示出CYP 3A 4抑制活性,IC 50值为0.022 mg/ml。生物测定引导的纯化得到9个化合物,3-(对羟基苯基)丙酸(1)、异甘草素(2)、(3R)-vestitol(3)、甘草吡喃香豆素(4)、4-羟基愈创木酚芹菜糖苷(5)、甘草苷(6)、甘草素7,4 '-二葡萄糖苷(7)、甘草苷芹菜糖苷(8)和葡萄糖甘草苷芹菜糖苷(9)。在这些化合物中,3、7和5显示出有效的CYP 3A 4抑制活性,IC 50值分别为3.6、17和20 μ m。甘草素(10)是甘草的主要成分,但对CYP 3A 4抑制无活性。
The extract of licorice (Glycyrrhiza uralensis FISHER, Leguminosae) showed CYP3A4 inhibitory activity with the IC50 value of 0.022 mg/ml. Bioassay-guided purification afforded nine compounds, 3-(p-hydroxyphenyl)propionic acid (1), isoliquiritigenin (2), (3R)-vestitol (3), licopyranocoumarin (4), 4-hydroxyguaiacol apioglucoside (5), liquiritin (6), liquiritigenin 7,4'-diglucoside (7), liquiritin apioside (8), and glucoliquiritin apioside (9). Among these compounds, 3, 7, and 5 showed potent CYP3A4 inhibitory activities with IC50 values of 3.6, 17, and 20 mu m, respectively. Glycyrrhizin (10), a main constituent of licorice, however, was inactive for CYP3A4 inhibition.
