Abstract
A new lactone, collectindolide (1), as well as three known compounds, (S)-sydonic acid (2), (S)-hidroxysydonic acid (3), and indole-3-aceticacid (4) were obtained from the liquid media of Colletotrichum gloeosporioides, which was obtained from Artocarpus heterophyllus. The chemical structures of 1-4 were established by spectroscopic analyses, including NMR experiments and by HR-ESI-TOF-MS mass spectroscopy. Compounds 1-4 were evaluated for their cytotoxicity against murine leukaemia P-388 cell lines by MTT assay. Antibacterial activity of compounds 1-4 was also assayed against four bacteria. Phytochemical investigation of the genus Colletotrichum derived from the plant genus Artocarpus is reported for the first time.
