Biosynthetic studies using 13C- and 2H-labeled compounds revealed that the carbon skeletons of cochleamycins A and B were derived from eight acetic acid units and one propionic acid unit with the introduction of an acetoxy group at C-10, which was replaced by an isobutyryl residue derived from valine in cochleamycins A2 and B2.

Novel antitumor antibiotics cochleamycins A, A2, B and B2 (Fig. 1) were isolated from the culture broth of Streptomyces sp. DT136. They were purified by column chromatography on silica gel, reversed phase HPLC and then isolated as colorless powder. Cochleamycins showed growth inhibition against tumor cells in vitro.

The structure of cochleamycins A, A2, B and B2 (Fig. 1), novel antitumor antibiotics, were elucidated by NMR spectral analysis. Cochleamycins were found to possess novel carbocyclic skeletons.
