Abstract

Two undescribed diterpenoids (1–2) and three lignans (3a/3b, 4a), together with sixteen known compounds (4b, 5–9, 10a/10b–14a/14b) were obtained from the stems of Tripterygium wilfordii (T. wilfordii). The structures of these new compounds were elucidated by detailed spectroscopic analyses, and their absolute configurations were estabished by ECD calculations. Some compounds exhibited moderate inhibitory activities against IL-6 production in LPS-stimulated RAW 264.7 macrophages in vitro. Compound 5 showed significant anti-inflammatory activity in vitro (IC₅₀, 0.77 μM) and inhibited macrophage polarization towards a pro-inflammatory phenotype.

威灵仙茎中的二萜和木脂素及其抗炎活性。

从 Tripterygium wilfordii（T. wilfordii）的茎中获得了两种未被描述的二萜类化合物（1-2）和三种木脂素（3a/3b, 4a），以及 16 种已知化合物（4b, 5-9, 10a/10b-14a/14b）。通过详细的光谱分析阐明了这些新化合物的结构，并通过 ECD 计算确定了它们的绝对构型。一些化合物在体外对 LPS 刺激的 RAW 264.7 巨噬细胞产生的 IL-6 有中等程度的抑制作用。化合物 5 在体外表现出明显的抗炎活性（IC50，0.77 μM），并抑制巨噬细胞向促炎表型极化。
