Mutactimycin PR, a new anthracycline antibiotic from Saccharothrix sp. SA 103. II. Physico-chemical properties and structure elucidation.
A new antibiotic termed mutactimycin PR (1) was isolated along with the known mutactimycin C (2) from the fermentation broth of Saccharothrix sp. SA 103. The two compounds belong to the anthracycline group. The structure of these antibiotics was elucidated with the aid of NMR and mass spectrometric investigations. The novel compound mutactimycin PR was characterized as 5,12 Naphtacenedione, 7-[(6-deoxy-3-O-methyl-alpha-L-mannopyranosyl)oxy]-4-[(6-deoxy-alpha-L-mannopyranosyl)oxy]-7,8,9,10-tetrahydro-6,9,11-trihydroxy-9 methyl.
