A known strain of S. antibioticus was found to produce a compound designated simocyclinon D8 (44) [31]. The compound exhibits antibiotic activity against Gram-positive bacteria and cytostatic effects against various cancer cells. Its structure and biosynthesis were clarified on the basis of physical-chemical methods, mainly by ID and 2D NMR and ESI-MS. It was found that during its biosynthesis the incorporation of 180 into the aminocoumarine residue is probably catalyzed by a monooxygenase.
