Microsphaeropsisin A, a new sesquiterpenoid isolated from the mangrove endophytic fungus (No. DZ39).
A new sesquiterpenoid compound, microsphaeropsisin A (1), together with three known dihydroisocoumarin compounds, (R)-mellein (2), 4-hydroxymellein (3) and 5-hydroxymellein (4) were isolated from the culture of the mangrove fungus (No. DZ39). The structure of the new compound was established by comprehensive spectral analysis, especially 2D NMR spectroscopy.
