Abstract

WF-3161 is an antitumor Antibiotic produced by a strain of fungus, Petriella guttulata. The Antibiotic was purified by solvent extraction and a combination of silica gel and reverse phase column chromatography. The chemical structure of the Antibiotic (C31H44N4O6, mp 181-183 degrees C) was found to be a cyclic tetrapeptide consisting of phenylalanine, leucine, pipecolinic acid and 2-amino-8-oxo-9,10-epoxydecanoic acid. WF-3161 inhibited the growth of Trichophyton asteroides. It prolonged survival period of mice bearing leukemia P-388 with a high therapeutic index.
