title: Metabolites of microorganisms. 247. Phenazines from Streptomyces antibioticus, strain Tü 2706.
abstract: From a strain of Streptomyces antibioticus seven yellow phenazines were isolated. The antibacterially most active antibiotic was identified as (-)-saphenamycin, a second one with compound DC-86-Y (saphenic acid). Three compounds were new: Saphenic acid methyl ether, 6-acetylphenazine-1-carboxylic acid and an inseparable mixture of fatty acid esters of saphenic acid. Two simple phenazines were phenazine-1-carboxylic acid (tubermycin B) and unsubstituted phenazine, which was isolated for the first time from a microorganism.
