Novel Polyethers from Screening Actinoallomurus spp.

ABSTRACT: In screening for novel antibiotics, an attractive element of novelty can be represented by screening previously underexplored groups of microorganisms. We report the results of screening 200 strains belonging to the actinobacterial genus Actinoallomurus for their production of antibacterial compounds. When grown under just one condition, about half of the strains produced an extract that was able to inhibit growth of Staphylococcus aureus. We report here on the metabolites produced by 37 strains. In addition to previously reported aminocoumarins, lantibiotics and aromatic polyketides, we described two novel and structurally unrelated polyethers, designated α-770 and α-823. While we identified only one producer strain of the former polyether, 10 independent Actinoallomurus<
