Notizen: ---In addition to the known gabosines A (4), B (5) and C (6), three new gabosines L (1), N (2) and O (3) were detected by chemical screening as secondary metabolites of Streptomyces (strains GT 041230, GT 051024 and S 1096). The constitutions of 1, 2 and 3 were established by spectroscopic techniques and derivatization reactions. The absolute stereochemistry of 1 and 2 was determined by Helmchen's method and has been verified in the case of gabosine N (2) by X-ray analysis. The DNA-binding properties of the gabosines were investigated and analyzed by binding studies using a recently developed thin-layer chromatography technique (bimolecular-chemical screening).
