description Deep-sea sediment-derived bacterium may make full use of self-genes to produce more bioactive metabolites to adapt to extreme environment, resulting in the discovery of novel metabolites with unique structures and metabolic mechanisms. In the paper, we systematically investigated the metabolites in structurally diversity and their biosynthesis from the deep-sea sediment-derived bacterium <i>Agrococcus</i> sp. SCSIO 52902 based on OSMAC strategy, Molecular Networking tool, in combination with bioinformatic analysis. As a result, three new compounds and one new natural product, including 3<i>R</i>-OH-1,6-diene-cyclohexylacetic acid (<b>1</b>), linear tetradepsipeptide (<b>2</b>), <i>N</i><sup>1</sup>,<i>N</i><sup>5</sup>-di-<i>p</i>-(<i>EE</i>)-coumaroyl-<i>N</i><sup>10</sup>-acetylspermidine (<b>3</b>) and furan fatty acid (<b>4</b>), together with nineteen known compounds (<b>5</b>–<b>23</b>) were isolated from the ethyl acetate extract of SCSIO 52902. Their structures were elucidated by comprehensive spectroscopic analysis, single-crystal X-ray diffraction, Marfey’s method and chiral-phase HPLC analysis. Bioinformatic analysis revealed that compounds <b>1</b>, <b>3</b>, <b>9</b> and <b>13</b>–<b>22</b> were closely related to the shikimate pathway, and compound <b>5</b> was putatively produced by the OSB pathway instead of the PKS pathway. In addition, the result of cytotoxicity assay showed that compound <b>5</b> exhibited weak cytotoxic activity against the HL-60 cell line.
