Goodyeroside A, a natural product isolated from the Goodyera species, possesses significant hepatoprotective activity and has a novel skeleton not previously observed in other synthetic drugs used for the treatment of hepatitis. Herein, we report a highly stereoselective synthesis of goodyeroside A and related analogs with varying substituents at the α position of the carbonyl group to explore the structure-activity relationships of goodyeroside A. The absolute configuration of analog 5d was confirmed by single crystal X-ray analysis. The results from in vitro and in vivo studies indicate that 5a, the fully acetylated compound of goodyeroside A, is worthy of further investigation as a lead to identify novel hepatoprotective agents.
Goodyeroside A 是一种从 Goodyera 物种中分离出来的天然产物,具有显著的保肝活性,其新颖的骨架是以前在其他用于治疗肝炎的合成药物中未观察到的。在此,我们报告了一种高度立体选择性的合成方法,即在羰基的 α 位上用不同的取代基合成 goodyeroside A 及相关类似物,以探索 goodyeroside A 的结构-活性关系。体外和体内研究的结果表明,5a 是一种完全乙酰化的好耶罗苷 A 化合物,值得进一步研究,以寻找新型保肝药物。
