Secondary metabolites from isolated from and evaluation of their cytotoxic and antibacterial activities.

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