    • Fungal material: The fungus strain Penicillium sp. was isolated from the bark of mangrove Acanthus ilicifolius Linn. (endophyte) collected from the South China Sea in September, 2005. The strain was deposited in the School of Life Science and the School of Chemistry and Chemical Engineering, Sun Yat-sen (Zhongshan) University, Guangzhou, PR China with the access code ZJ-2005032. Ninety liters of the fungal strain were cultivated in liquid medium (10.0 g of glucose, 2.0 g of yeast extract, 2.0 g of peptone in 1 L of seawater, in a 1.0 L Erlenmeyer flasks each containing 400 mL of culture broth) at 27 °C without shaking for five weeks.

    • 2O. The EtOAc solution was evaporated to give a dark yellow residue (4.6 g). The extract was subjected to a silica gel CC (200-300 mesh, 500 g) eluted with a gradient of petroleum ether and EtOAc and yielded 1 (15.5 mg) from the EtOAc/petroleum ether (100:0) fractions.

    • 4 were added. The solution was stirred at room temperature for 12 h. The reaction mixture was filtered through Celite, and the residue was washed with acetone (20.0 mL). The combined filtrates were evaporated to dryness under reduced pressure and the product 1a was purified by a silica gel CC using 80:20 EtOAc/petroleum ether (v/v).
