摘要:
New two pebrolide type sesquiterpenoids, deacetoxy-1-deoxypebrolide (1) and 7'-hydroxyisoasperphenamate (2) along with asperphenamate (3), mycophenolic acid (4) and 1-deoxypebloride (5) were isolated from Penicillium sp. IFM 62525. Their structures were established from spectroscopic and chemical method. The absolute stereochemistry of 2 was confirmed by Marfey's method. Antifungal activities of these compounds were tested and 4 showed strong activity.
