Abstract
A new highly oxygenated cycloheptane derivative crustane (1), along with fourteen known compounds (2-15) were isolated from Penicillium crustosum JT-8. The structure of compound 1 was determined by extensive spectroscopic data, DP4+ probability analyses and dimolybdenum CD method. Compound 1 exhibited moderate antibacterial activity against Staphylococcus aureus with MIC of 4.0 μg/mL.
