Two new aminoglycoside antibiotics, sporaricins A (C17H35N5O5) and B (C15H32N4O4) produced by a rare actinomycetales, Saccharopolyspora hirsuta subsp. kobensis have been isolated by column chromatography on a cation-exchange resin. Sporaricin A is highly active against Gram-positive and Gram-negative bacteria including aminoglycoside-resistant strains.
