摘要： Two new brominated azaphilones, 5-bromoisorotiorin (1) and penicilazaphilones H (2), along with a known azaphilone, 5-bromosclerotiorin (3) were isolated from the marine-derived fungus Penicillium sclerotiorum E23Y-1A cultivated on the solid rice medium with 3.3%NaBr. The structures of three compounds were eluci-dated based on 1D and 2D NMR spectra as well as HRESIMS data. Their absolute configurations were determined by ECD spectra analysis. Compounds 1-3 showed moderate antibacterial activities against Staphylococcus aureus ATCC 25923 with diameter of the inhibition zones of 8.08 +/- 0.01, 7.50 +/- 0.05 and 8.17 +/- 0.05 mm, respec-tively, as well as compound 3 exhibited weak inhibitory activity against AChE.
