Abstract

Three eudesmanolide sesquiterpene-phenol hybrids, atramacronoids A−C (1−3), featuring an unusual 6/6/5/5/6 skeleton furnished by forming an unexpected C-8−C-16 linkage, were obtained from the rhizomes of Atractylodes macrocephala. Their structures and absolute configurations were elucidated by spectroscopic data analysis, chemical calculations, combined with X-ray diffractions. The plausible biosynthetic pathways for compounds 1−3 are proposed. Surprisingly, compound 1 exhibited cytotoxicity against SGC-7901 cells by inducing cells apoptosis, which might relate to the promotion of synthesis of neutrophil elastase.

从苍术的根状茎中分离出三种具有前所未有的C - C连锁的苦参甾醇倍半萜酚类化合物——苍术类A−C

从苍术的根状茎中分离得到3个倍半萜酚类化合物，atramacronoids A−C(1−3)，具有罕见的6/6/5/5/6骨架，形成了一个意想不到的C-8−C-16连锁。通过光谱数据分析、化学计算和x射线衍射分析，确定了它们的结构和绝对构型。提出了化合物1 ~ 3的可行生物合成途径。令人惊讶的是，化合物1通过诱导细胞凋亡对SGC-7901细胞表现出细胞毒性，这可能与促进中性粒细胞弹性酶的合成有关。
