It is synthesized by a gene cluster found in environmental DNA and exhibits cytotoxic activity against human HCT116 cancer cells and Staphylococcus aureus. It has a role as an antibacterial agent, a toxin and an antineoplastic agent. It is an indolocarbazole alkaloid, a methyl ester, an organic heterohexacyclic compound and a secondary amino compound. It is functionally related to an erdasporine B."}]
