Abstract

Three steroids, ergosterol (1), ergosterol peroxide (2) and stigmasterol (3) have been isolated from endophytic fungus, Lasiodiplodia theobromae derived from the root of Aglaia argentea Blume. The steroids were isolated by vacuum chromatography and column chromatography, the chemical structure was established following the analysis of 1D-NMR, 2D-NMR, IR, MS and by comparison with previously reported spectra data. Ergosterol peroxide (2) and stigmasterol (3) were reported for the first time isolated from Lasiodiplodia theobromae endophytic fungus. Cytotoxic activities of the compounds were tested with resazurin assay against HeLa cervical cancer cells, compound 2 displayed strongest cytotoxic activities against HeLa cervical cancer cells with IC50 values of 0.28 µM, while compounds 1 and 3 showed IC50 values of 0.34 µM and 27.32 µM, respectively

Abstract

ABSTRACT. Steroids are secondary metabolic derivatives of terpenes containing the tetracyclic ring system known to exhibit fascinating pharmacological activity. Steroids are distributed in various genera of endophytic fungi including Fusarium genus which lives inside a higher tree such as Chisocheton macrophyllus. The purpose of this research is to identify and characterize the chemical structure of steroids generated by F. phaseoli, an endophytic fungus obtained from C. macrophyllus roots, as well as to assess their antibacterial activity against Escherichia coli and Staphylococcus aureus. The brown rice medium was fermented with F. phaseoli for six weeks before extraction with ethyl acetate. The extracts yielded four compounds, identified using spectroscopic methods such as FTIR, HRTOF-MS, 1D, and 2D NMR, and then compared to previously described compounds. Compounds 1-4 were identified as ergosterol (1), ergosterol peroxide (2), atroside (3), and cerevisterol (4). The four isolated compounds were evaluated for antibacterial activity against Staphylococcus aureus ATCC 6538 and Escherichia coli ATCC 11229 and displayed activity with MIC50 values of 500 µg/mL. Keywords: Antibacterial activity; Chisocheton macrophyllus; Fusarium phaseoli; steroids.
