مستخلص: | Pleosmaranes A–R (1–18), 18 new isopimarane-type diterpenoids, together with four known analogs (19–22), were isolated from the mangrove endophytic fungus Pleosporalessp. HNQQJ-1. Their structures and absolute configurations were established by analysis of their spectroscopic data and electronic circular dichroism (ECD) calculations. Compounds 1–9possess an unusual aromatic B ring and a 20-nor-isopimarane skeleton. Compounds 15–17contain a unique 2-oxabicyclo[2.2.2]octane moiety. Compound 18features an unexpected 2-oxabicyclo[3.2.1]octane moiety. Compounds 8and 12exhibited a moderate inhibitory effect against LPS-induced NO production, with IC50values of 19 and 25 μM, respectively. |
