Abstract
Two new benzoate derivatives, ethyl 3,5-dimethoxy-2-propionylbenzoate (1) and ethyl 3,5-dihydroxy-2-propionylbenzoate (2), and one new phenylacetate derivative, ethyl 3,5-dimethoxy-2-propionylphenylacetate (3), together with 9 known compounds, were isolated from the fermentation of Engyodontium album derived from deep sea sediment. Their structures were elucidated by spectroscopic techniques, such as NMR, IR and HRESIMS. Compound 3 exhibited inhibitory activities against methicillin-resistant Staphylococcus aureus ATCC 43300 (MRSA) and Vibrio vulnificus, with MIC values of 7.8 and 15.6 μg/mL, respectively.
