摘要：

A new xanthone (penicillanthone, 1) and three new diphenyl ether derivatives (penicillidic acids A-C, 2-4) together with 14 known compounds (5-18) were isolated from the soil-derived fungus Penicillium aculeatum PSU-RSPG105. The structures were elucidated by spectroscopic analyses. The absolute configuration of compound 1 was determined using the Snatzke's method whereas those of compounds 2-4 was established by comparison of their optical rotations with those of structurally related compounds. Compound 5 exhibited mild antimycobacterial activity against Mycobacterium tuberculosis with an MIC value of 25 mu g mL (1) and was noncytotoxic to noncancerous Vero cells. In addition, altenusin (12) displayed moderate antibacterial activity against methicillin-resistant Staphylococcus aureus with an MIC value of 32 mu g mL(-1) and mild activity towards Vero cells with an IC50 value of 19.46 mu M.
