The molecule is a pyrazinoindole with a disulfide bridge spanning a dioxo-substituted pyrazine ring. It is an antibiotic isolated from the microbial strains Sphingomonas and Aspergillus fumigatus, and exhibits cytotoxic activity against four human cancer cell lines: HCT-116, A549, AGS, and DU145. It has a role as an antimicrobial agent, an antineoplastic agent and an Aspergillus metabolite. It is an organic disulfide, a pyrazinoindole, a C-nitro compound and an organic heterotetracyclic compound.
