Hypersubones D-H (1-5), five new polycyclic polyprenylated acylphloroglucinols (PPAPs) type metabolites with intriguing adamantane and homo-adamantane skeletons, were characterized from aerial parts of Hypericum subsessile. Compounds 1-2 were elucidated to share an adamantane core with 28,29-expoxide moiety, while 3-5 were homo-adamantane type PPAPs sharing a1,2-dioxepane ring system. Their structures were determined on the basis of comprehensive NMR and MS spectroscopic data.The anti-adipogenesis activities of these isolates were evaluated through employing 3T3-L1 cells as an in vitro system using oil red O staining, and compounds 1, 2 and 5 were able to significant inhibit the adipocyte differentiation, which implied that these compounds possessed anti-adipogenic activity.
从无柄金丝桃的地上部分分离得到 5 个新的多环多聚异戊烯基酰基间苯三酚(PPAP)类代谢物 Hypersubones D-H(1-5),它们具有有趣的金刚烷和同金刚烷骨架。化合物 1-2 被阐明为具有 28,29-环氧部分的金刚烷核心,而 3-5 为同金刚烷型 PPAP,共享 1,2-二氧杂环戊烷环系统。基于全面的 NMR 和 MS 光谱数据确定了它们的结构。通过使用油红 O 染色,采用 3T3-L1 细胞作为体外系统,评估了这些分离物的抗脂肪生成活性,化合物 1、2 和 5 能够显著抑制脂肪细胞分化,这表明这些化合物具有抗脂肪生成活性。
