long history. The investigation of S. cuneata led to the isolation and identification of twenty-three secondary metabolites, including two new compounds, sargentodoxosides A (1) and B (2), and twenty-one known ones (3-23). Their structural characterization was conducted by HRESIMS, 1 D and 2 D NMR spectra. All the isolated compounds were assayed for their agonistic activities against the farnesoid X receptor
摘要 Sargentodoxa cuneata (Oliv.) Rehd。et Wils是一种治疗急性阑尾炎、风湿性关节炎、腹痛、痛经的中药,历史悠久。对S. cuneata的研究导致分离和鉴定了 23 种次生代谢物,包括两种新化合物,即 sargentodoxosides A ( 1 ) 和 B ( 2 ),以及 21 种已知化合物 ( 3-23)。它们的结构表征是通过 HRESIMS、1 D 和 2 D NMR 光谱进行的。测定了所有分离的化合物对法尼醇 X 受体 (FXR) 的激动活性。九种分离的化合物在 0.1 µM 时对 FXR 显示出显着的激动作用,表明它们可以作为开发 FXR 激动剂的潜在药物。
