fermentation broth of a coral-associated bacterium Labrenzia sp. The structure and absolute
configuration of 1 was determined by spectroscopic methods and Marfey's analysis. Overall,
1 showed antimicrobial activity against Ralstonia solanacearum SUPP1541 and
Micrococcus luteus ATCC9341 with MIC values of 25 and 50 µg ml− 1, respectively, and
cytotoxicity against P388 murine leukemia cells with an IC50 of 13 µM.
