Groenlandicine 是从黄连中分离得到的一种原小檗碱生物碱。Groenlandicine 对人类重组醛糖还原酶 (HRAR) 具有中度的抑制作用，IC50 值为 154.2 μM。Groenlandicine 能诱导拓扑异构酶 I (topoisomerase I) 介导的 DNA 裂解。
Groenlandicine is a protoberberine alkaloid isolated from Coptidis Rhizoma. Groenlandicine exhibits moderate inhibitory effect with IC50 value of 154.2 μM for human recombinant aldose reductase (HRAR)[1]. Groenlandicine selectively induces topoisomerase I-mediated DNA cleavage[2].
