黄芩苷

黄芩苷（英語：Baicalin）是一种黄酮类化合物，是黄芩素（Baicalein）与葡萄糖醛酸形成的糖苷，提取自黄芩（Scutellaria baicalensis）、盔状黄芩（Scutellaria galericulata）等植物。 黄芩苷存在于草药双黄连及小柴胡汤中。 黄芩苷及其糖苷配基黄芩素都是苯二氮䓬受体的正别构调节剂（英语：positive allosteric modulator）。小鼠实验表明黄芩苷是抗焦虑药，但不是镇静剂或肌肉松弛剂。黄芩和盔状黄芩的抗焦虑作用可能源自黄芩苷及其它黄酮类化合物。 黄芩苷是脯氨酰寡肽酶（英语：prolyl endopeptidase）抑制剂。它会促使胰脏癌细胞凋亡。 Su, Hai-xia; Yao, Sheng; Zhao, Wen-Feng; Li, Min-jun; Liu, Jia; Shang, Wei-Juan; Xie, Hang; Ke, Chang-Qiang; Hu, Hang-Chen; Gao, Mei-na; Yu, Kun-Qian; Liu, Hong; Shen, Jing-Shan; Tang, Wei; Zhang, Lei-ke; Xiao, Geng-fu; Ni, Li; Wang, Dao-wen; Zuo, Jian-Ping; Jiang, Hua-Liang; Bai, Fang; Wu, Yan; Ye, Yang; Xu, Ye-Chun.
