Comprehensive Summary

Six new acorane-type sesquiterpenes, named penijanacoranes A—F (16), as well as one known eudesmane sesquiterpenoid 1α,6β,11-eudesm-triol (7) have been isolated from a deep-sea-derived fungus Penicillium janthinellum SH0301. Their structures and absolute configurations were established by the comprehensive spectroscopic analysis, TDDFT-ECD calculations, and X-ray diffraction. Penijanacorane A (1) was identified as a rare acorane-type sesquiterpene lactone featuring a novel 6/5/6 tricyclic system, while penijanacoranes E and F (5 and 6) represented undescribed examples of nor-acorane sesquiterpenes at C-1. Penijanacorane C (3) exhibited significant inhibitory activity against LPS-induced NO production in Raw264.7 macrophages with an IC50 value of 6.23 μM, which was more potent than that of positive control dexamethasone (IC50 = 11.49 μM). This study expanded the chemical diversity of acorane-type sesquiterpenoids and revealed that compound 3 was a potential molecule for anti-inflammatory agents.
