Abstract
Two Indonesian Streptomyces strains, ICBB8309 and ICBB8415, were investigated for their ability to produce antibiotic compounds. In addition to the known antibiotics actiphenol, naramycin B, and sabaramycin, six new angucyclinones were identified. The isolation, structure elucidation and biological activities for the six new compounds are presented. The angucyclinones 7-deoxo-6-deoxy-7-hydroxy-8-O-methylrabelomycin, 1-deoxo-1-hydroxy-8-O-methylrabelomycin, and the angucycline 7-deoxo-7-hydroxy-1-O-α-rhamnosy1-8-O-methyltetrangulol have common angular backbones, while angucyclinone C, limamycin A, and limamycin B appear to be rearranged angucyclinones.
