Common NameHomocereulide
DescriptionHomocereulide is a cyclic dodecadepsipeptide belonging to the class of microbial metabolites. Isolated from the marine bacterium Bacillus cereus, it is an analog of the emetic toxin cereulide and exhibits notable biological activity. The chemical structure of homocereulide comprises l-O-Val-l-Val-d-O-Leu-d-Ala and l-O-allo-Ile-d-Val-d-O-Leu-d-Ala units, as confirmed by NMR spectroscopy and LC-MS analysis, which demonstrated consistency with natural products (PMID:30665680 ). The synthesis of homocereulide was achieved through liquid phase fragment condensation, allowing for a detailed examination of its properties (PMID:30665680 ). In functional assays, homocereulide displayed higher toxicity in HEp-2 cells at a concentration of 1.39 nM compared to cereulide, which exhibited toxicity at 3.95 nM (PMID:30665680 ). This suggests that while cereulide is the predominant component in broth cultures, homocereulide may also play a significant role in the biological effects associated with B. cereus (PMID:30665680 ). The exploration of homocereulide's structure and effects contributes to our understanding of the toxicological profiles of bacterial metabolites.
