Fermentation and Biological Activity KW - OMPHALOTUS OLEARIUS KW - OMPHALOTIN KW - CYCLOPEPTIDE KW - 3-(3-INDOLYL)-NMETHYLPROPANAMIDE KW - NEMATICIDAL KW - MELOIDOGYNE INCOGNITA KW - CAENORHABDITIS ELEGANS N2 - Omphalotin (l), a new cyclic peptide possessing strong and selective nematicidal activity against the plant pathogenic Meloidogyne incognita, was isolated from cultures of the basidiomycete Omphalotus olearius together with the antibiotic sesquiterpene illudin M (2)and the inactive 3-(3-indolyl)-Nmethylpropanamide (3). Omphalotin (1)is only weakly active against the saprophytic nematode Caenorhabditis elegans, it is weakly cytotoxic at 100 pg/ml but shows no phytotoxic, antibacterial or antifungal activities. The fermentation of 0. olearius and the production of the metabolites as well as the evaluation of their biological activities are reported UR - https://drive.google.com/file/d/1AB42pLlM4eMoOv00crjXa6Suc8XzY9uv/view?usp=drivesdk ER -
