It is a purple chromobacterial pigment that has antibacterial, antifungal, antiprotozoan, and anticancer properties. It has a role as a bacterial metabolite, an antineoplastic agent, an apoptosis inducer, an antibacterial agent and an antifungal agent. It is a member of hydroxyindoles, a member of pyrroles, a member of oxindoles and an olefinic compound. It is functionally related to a proviolacein."}]
