Chrysosplenetin 是青蒿 (Artemisia annua) 和其他几种中草药中的多甲氧基化黄酮类化合物之一。 Chrysosplenetin 抑制P-gp 活性并逆转由青蒿素 (ART) 诱导的上调的 P-gp 和 MDR1 水平。 Chrysosplenetin 显着增强 ART 在大鼠血浆水平和抗疟疾功效，部分因为其对大鼠 CYP3A 的非竞争性抑制作用。

Background:

Chrysosplenetin is one of the polymethoxylated flavonoids in Artemisia annua L. (Compositae) and other several Chinese herbs. Chrysosplenetin inhibits P-gp activity and reverses the up-regulated P-gp and MDR1 levels induced by artemisinin (ART). Chrysosplenetin significantly augments the rat plasma level and anti-malarial efficacy of ART, partially due to the uncompetitive inhibition effect of Chrysosplenetin on rat CYP3A[1]. CYP3A
