[The antineoplastic antibiotic polypeptide 308 produced by Actinomadura recticatena. Its isolation and physicochemical properties]. / Protivoopukholevyi antibiotik-polipeptid 308, produtsiruemyi Actinomadura recticatena. Vydelenie i fiziko-khimicheskie svoistva.

ABSTRACT

A antitumor antibiotic belonging to the group of polypeptide antibiotics containing chromophore was isolated from the culture of Actinomadura recticatena Terekhova, Preobrazhenskaya et Galatenko, 1984, strain 308. Biosynthesis, isolation, physicochemical and biological properties of the antibiotic are described. The results of elemental analysis, the melting point, optical properties, UV, IR and NMR spectra and the data on acid hydrolysis showed that antibiotic 308 was most closely related to antibiotic BBM-928 A.
