Abstract: Two new quinazoline derivatives versicomides E (1) and F (2), and 10 known compounds (3-12) were isolated from the moss endophytic fungus Aspergillus sp. Their structures were determined on the basis of extensive spectroscopic data analysis and ECD calculations. Among them, the compound 7 (6-hydroxy-3-methoxyviridicatin) was first reported as a natural product. Inhibition on LPS-induced NO production in RAW 264.7 murine macrophages found that compounds 5, 7 and 8 showed significant inhibitory effects on NO production, with IC50 values of 49.85, 22.14 and 46.02 μM respectively.
