It is isolated from the culture broth of Streptomyces uncialis and exhibits cytotoxicity against human breast cancer MCF- cells. It has a role as an antineoplastic agent. It is an organic heteropentacyclic compound, a lactam, an organochlorine compound, a tertiary alcohol, a cladoniamide and a secondary carboxamide."}]
