Abstract

Antibiotic SB22484 is a novel member of the aurodox type antibiotic group produced in submerged-fermentation cultures of Streptomyces sp. NRRL 15496.
The antibiotic complex is composed of two pairs of isomers with MW's of 752 and 766. The individual isomers, which were separated by preparative HPLC, equilibrate to a mixture of the isomer pair when left in aqueous solution.
In vitro, SB22484 antibiotics strongly inhibited neisseriae and were also active against Streptococci, Ureaplasma urealyticum and Haemophilus influenzae.
