Abstract

Two novel angucyclinone-type Antibiotics, simocyclinones D4 and D8, were detected in the mycelium extract of Streptomyces antibioticus Tü 6040 by HPLC-diode-array and HPLC-electrospray-mass-spectrometry screening. The compounds show Antibiotic activities against Gram-positive bacteria and cytostatic effects on various tumor cell lines.
