从深海真菌Penicillium sp. F00120中分离得到一种新的倍半萜烯甲基环戊烯二酮-青霉菌素B(1),以及三种已知的倍半萜烯环己烯酮(2-4)。青霉素B(1)是第一个以倍半萜烯环戊烯二酮为骨架的天然产物,通过NMR和MS光谱数据分析确定了其结构,同时通过单晶X射线实验确定了其绝对构型。提出了1的环戊烯酮骨架的合理生物合成途径。青霉素B(1)毒性低,通过破坏氧化应激机制抑制肾纤维化,是一种新型的肾脏保护剂。
A novel sesquiterpene methylcyclopentenedione, penicilliumin B (1), was obtained from a deep sea-derived fungus Penicillium sp. F00120, together with three known sesquiterpene cyclohexenones (2–4). Penicilliumin B (1), presenting the first example with the sesquiterpene cyclopentenedione skeleton as natural products, was structurally determined by analysis of the NMR and MS spectroscopic data, while the absolute configurations were assigned by single-crystal X-ray experiments. The plausible biosynthetic pathway of the unusual cyclopentenone skeleton of 1 was proposed. Penicilliumin B (1), with low toxicity, was showed significant potential to inhibit the kidney fibrogenic action in vitro, by a mechanism dependent on disruption of oxidative stress, presenting a new type of promising renoprotective agent.
