Popis: | A new compound, 8-propionate-2-β-(D+)-glucosyl-9,10-pyranopyridine, was isolated from the chloroform extract of a Streptomyces species. The structure of the compound was confirmed by spectroscopic techniques including UV, IR, HR-ESI-MS, 1H-NMR, 13C-NMR, 1H-1H COSY and HMBC (long range coupling) spectra. The compound showed significant antibacterial activity against Gram-positive bacteria. The minimum inhibitory concentrations (MIC) of the isolated compound against Bacillus megaterium, Streptococcus β-haemolyticus, Bacillus subtilis, Escherichia coli, Salmonella typhi and Shigella dysenteriae were found to be 0.16, 0.08, 0.08, 0.04, 0.08 and 0.08 μM, respectively.
