【 摘 要 】

Protulactones A (1) and B (2), two new polyketide-derived fungal metabolites, have been isolated from an EtOAc extract of the marine-derived fungus Aspergillus sp. SF-5044 by various chromatographic methods. The structures of 1 and 2 were mainly determined by analysis of the NMR spectroscopic data and MS data, along with chemical methods such as Mosher method. Protulactones A (1) and B (2) are new members of polyketide-derived secondary metabolites, possessing unique ring systems among the fungal metabolites produced by the genus Aspergillus.
