چکیده
Eight secondary metabolites were isolated from submerged cultures of the ascomycete A111-95 during a search for new nematicidal metabolites. (-)-Galiellalactone (7) and compound 2 are metabolites previously obtained from cultures of Galiella rufa while the compounds 1, 3, 4, 5, 6 and 8 (3 and 4 were obtained as an unseparable mixture), were isolated as natural products for the first time. Compound 2, pregaliellalactone (5) and the mixture of 3 and 4 showed nematicidal activities towards Caenorhabditis elegans and Meloidogyne incognita. All compounds showed moderate or weak cytotoxic activities.

Actinomycetes are a source of a broad variety of secondary metabolites with diverse biological activities, such as antifungi, antibiotics and antitumorals; many of which have been developed for clinical use. In this study, 34 actinomycetes from untouched soils were isolated from Alborz Province-Iran. Evaluation ofantifungal and anti bacterial activities of these isolates, demonstrated the capab...
متن کاملSecondary metabolites and biological activities of Talaromyces sp. LGT-2, an endophytic fungus from Tripterygium wilfordii
Abstract In the present study, eleven compounds (1-11) including nine alkaloids (1-9), one triterpenoid saponin (10) and one formamide (11) were isolated from Talaromyces sp. LGT-2, an endophytic fungus from Tripterygium wilfordi. Their structures were determined based on NMR and ESI-MS spectral data, as well as comparing with previous literature data. This is the first report of the isolation ...
