It is isolated from a marine bryozoan Pterocella vesiculosa and has been found to exhibit moderate antitumour activity against the P388 murine leukemia cell line. Additionally it shows antimicrobial activity towards the Gram-positive bacterium Bacillus subtilis and the fungi Candida albicans and Trichophyton mentagrophytes. It has a role as a metabolite, an antifungal agent, an antineoplastic agent and an antibacterial agent. It is a member of beta-carbolines, an organobromine compound, an aromatic ether and an alkaloid."}]
