摘要
Four new alpha-pyrone-containing metabolites, wailupemycins A-C (1-3) and 3-epi-5-deoxyenterocin (4), were isolated together with known compounds enterocin (6) and 5-deoxyenterocin (5) from a Streptomyces sp. cultured from shallow water marine sediments. The structures of the new compounds were determined through the interpretation of spectral data. Compound 1 exhibited antimicrobial activity towards the Gram-negative bacterium Escherichia coli, while compound 4 inhibited the growth of Staphylococcus aureus.
