عنوان انگلیسی Isolation and structure elucidation of phenazine derivative from Streptomyces sp. strain UICC B-92 isolated from Neesia altissima (Malvaceae)
چکیده انگلیسی مقاله Background and Objectives: Endophytic actinomycetes have been known as a promising source for new antibiotics discovery against susceptible and resistant forms of pathogenic microorganisms. This study was aimed at determining antibacterial compound from Streptomyces sp. strain B-92 isolated from a medicinal plant Neesia altissima. Materials and Methods: Streptomyces sp. strain UICC B-92 was endophytic actinomycetes of N. altissima that obtained from Universitas Indonesia Culture Collection (UICC). Isolation and determination of bioactive compound were carried out using thin layer chromatography (TLC), nuclear magnetic resonance spectroscopy (NMR), and liquid chromatography mass spectrometry (LC-MS) analyses. An in vitro antibacterial assay of pure bioactive compound from the endophytic actinomycetes strain was performed against Bacillus cereus strain ATCC 10876, Escherichia coli strain ATCC 25922, Salmonella typhimurium strain ATCC 25241, Shigella flexneri strain ATCC 12022 and Staphylococcus aureus strain ATCC 25923. Results: The bioactive compound was identified as 4-((3S,4R,5S)-3,4,5-trihydroxy-6-(hydroxymethyl) tetrahydro-2H-pyran-2-yloxy) phenazine-1-carboxylic acid. In vitro antimicrobial assay showed that bioactive compound of Streptomyces sp. strain UICC B-92 exhibited antagonistic activities against two Gram-positive bacteria, viz, B. cereus strain ATCC 10876 and S. aureus strain ATCC 25923. Conclusion: The findings of this research showed that, bioactive compound of Streptomyces sp. strain UICC B-92 is suggested a new compound based on glycoside structure and its position.
