Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, International Journal of Systematic and Evolutionary Microbiology called Description of the bacterial RNA polymerase inhibitor GE23077-producer Actinomadura sp. NRRL B-65521T as Actinomadura lepetitiana sp. nov, Author is Dalmastri, Claudia; Gastaldo, Luciano; Berini, Francesca; Marinelli, Flavia; Marcone, Giorgia Letizia, which mentions a compound: 17739-45-6, SMILESS is BrCCOC1CCCCO1, Molecular C7H13BrO2, Synthetic Route of C7H13BrO2.
The filamentous actinomycete that produces the antibiotic GE23077 was isolated by the Lepetit Research Group from a soil sample collected in Thailand, and it was classified as a member of the genus Actinomadura on the basis of its morphol. and cell-wall composition Phylogenetic anal. based on 16S rRNA gene sequences indicated that this strain formed a distinct monophyletic line within the genus Actinomadura, and it was most closely related to Actinomadura bangladeshensis DSM 45347T (99.31% similarity) and Actinomadura mexicana DSM 44485T (98.94%). The GE23077-producing strain formed an extensively branched, non-fragmented vegetative mycelium; no pseudosporangia were formed and the arthrospores were organized in slightly twisted chains. The cell wall contained meso-2,6-diaminopimelic acid and the diagnostic sugar was madurose. The predominant menaquinone was MK-9(H6), with minor amounts of MK-9(H8) and MK-9(H4). The diagnostic phospholipids were phosphatidylinositol and diphosphatidylglycerol. The major cellular fatty acids were C16:0 and tuberculostearic acid (10-methyloctadecanoic acid), followed by minor amounts of C18:1ω9c, C16:1ω7c and 10-methylheptadecanoic acid. The genomic DNA G + C content was 71.77 mol%. Significant differences in the morphol., chemotaxonomic and biochem. data, and the low DNA-DNA relatedness between the GE23077-producing strain and closely related type strains clearly demonstrate that it represents a novel species of the genus Actinomadura, for which the name Actinomadura lepetitiana sp. nov. is proposed. The type strain is NRRL B-65521T(= LMG 31258T = DSM 109019T).
