title: Studies on cochleamycins, novel antitumor antibiotics. II. Physico-chemical properties and structure determination.
abstract: 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.
