摘要

The lookout for novel metabolites to overcome the threat imposed by antibiotic resistant pathogens is on the rise globally. The present study reports on the identification and characterisation of a new borrelidin derivative from Streptomyces rochei VL-16 strain that was isolated from the soil samples of Osudu Lake in Puducherry. The active compound produced by Streptomyces rochei VL-16 strain was purified sequentially by thin layer, column and high performance liquid chromatography techniques. The purified compound was subsequently identified as borrelidin through Q-TOF-HR-LCMS, FTIR and UV–Vis spectroscopy techniques. Based on integration proton NMR signals and HR-ESI–MS peak pattern, the compound was further identified as a new derivative of borrelidin. Its 3D structure was optimised using density functional theory. The new derivative obtained in this study was designated as borrelidin M (C28H41NO5, Mol. wt.471.3 g/mole). This derivative was found to exhibit potent inhibitory effects against the foodborne pathogens including Clostridium perfringens, Aeromonas hydrophila, Staphylococcus aureus, Listeria monocytogenes and Yersinia enterocolitica. Also, borrelidin M exhibited anticancer and anti-metastatic effects against A549 cell line with an IC50 value of 17.5 μM. Collectively, these findings indicated promising biomedical applications of this new derivative of borrelidin.
