Produced by Streptomyces spectabilis, it exhibits antiviral and antimalarial activity. It has a role as a bacterial metabolite, an antiplasmodial drug, an antiviral agent and a nematicide. It is a member of 4-pyranones, a C-nitro compound, a polyketide, a member of oxolanes and a ketene acetal. It is functionally related to a deoxyspectinabilin."}]
