title: Retymicin, galtamycin B, saquayamycin Z and ribofuranosyllumichrome, novel secondary metabolites from Micromonospora sp. Tü 6368. II. Structure elucidation.
abstract: A detailed screening of the secondary metabolite pattern from Micromonospora sp. strain Tü 6368 resulted in the isolation of ten compounds belonging to five different structural families. The structures of the novel compounds 1-(alpha-ribofuranosyl)-lumichrome (3), retymicin (7), galtamycin B (11) and saquayamycin Z (14) were assigned by spectroscopic methods and chemical transformations. This strain fits our hypothesis that the metabolite analysis of biosynthetically talented strains leads readily to novel compounds.
