    摘要: Novel aminoglycosides of the following formula ##STR1## wherein R.sub.1 and R.sub.2 are identical or different and each represents a hydrogen atom or a methyl group, R.sub.3 represents a hydrogen atom or an optionally substituted aminoacyl group having 2 to 4 carbon atoms in the acyl moiety, and when all of R.sub.1, R.sub.2 and R.sub.3 are hydrogen atoms, the methylamino group at the 4-position is not oriented trans to the hydroxyl groups at the 3- and 5-positions; and acid addition salts thereof, which are useful as antibiotics; and process for producing compounds containing the same.

    摘要: A process for producing an antibiotic, which comprises cultivating an antibiotic KA-6606-producing strain of an genus Saccharopolyspora in a nutrient culture medium, isolating the antibiotic KA-6606-containing substance from the culture broth, and separating from the resulting antibiotic KA-6606-containing substance at least one antibiotic selected from the group consisting of antibiotic KA-6606 VII, KA-6606 VIII, KA-6606 IX, KIA-6606 X, KA-6606 XI, KA-6606 XII, KA-6606 XIII, KA-6606 XIV, KA-6606 XV, KIA-6606 XVI and KA-6606 XVII; and novel antibiotics KA-6606 XII, XIII and XV to XVII.
