It has been isolated from the fungi Aspergillus viridinutans and the fungus Paecilomyces variotii derived from the inner tissues of the giant jellyfish Nemopilema nomurai. It has a role as a mycotoxin, an Aspergillus metabolite and an antibacterial agent. It is functionally related to a semiviriditoxin."}]
