It is isolated from Streptomyces sp. TC-1190 and exhibits growth inhibitory effects on a series of human tumour cell lines. It has a role as a metabolite, an antimicrobial agent and an antineoplastic agent. It is an ether, a lactam, a macrocycle, an organonitrogen heterocyclic compound, an organosulfur heterocyclic compound, a member of phenols, a secondary alcohol and a cyclopropanecarboxylate ester."}]
