Abstract
A novel pyrone derivative (1) bearing two fused five-member rings, together with two new naphthalenone derivatives (2, 3), as well as two known compounds (4, 5) were obtained from the endophytic fungus Fusarium sp. HP-2, which was isolated from “Qi-Nan” agarwood. The structures of the new compounds were elucidated by analysis of 1D and 2D NMR, and by HRESIMS spectra, as well as by comparison with the literature. Bioactivity results indicated that compound 3 showed weak acetylcholinesterase inhibitory activity.
