A new depsipeptide antibiotic, citropeptin. [PDF]
Agricultural and Biological Chemistry, 1990 An actinomycete identified as Streptomyces flavidovirens was found to produce a new cyclic hexadepsipeptide antibiotic, designated citropeptin. Citropeptin showed antitumor activity against P388 murine leukemia.
