Metabolite Identification
Common NameAlternatone A
DescriptionAlternatone A is a perylenequinone-related compound characterized by a unique tricyclo[6.3.1.02,7] dodecane skeleton. This metabolite was isolated from a soft-coral-derived strain of the fungus Alternaria alternata, highlighting its fungal origin (PMID:31659905 ). The chemical structure of alternatone A contributes to its notable cytotoxic properties, as demonstrated by its activity against the human hepatoma carcinoma HepG-2 cell line (PMID:34142621 ). Perylenequinones, including alternatone A, are known to participate in various biochemical pathways, often interacting with cellular components and influencing redox processes. The presence of such compounds in fungi suggests potential ecological roles, including defense mechanisms against predators or pathogens. The unique structural features of alternatone A may also allow it to engage in specific interactions with biological macromolecules, further underscoring its relevance in the study of natural products and their potential applications in cancer research.
