  • Title: Pyrrolidinones from the ascomycete fungus Albonectria rigidiuscula.
    Author: Li J, Liu S, Niu S, Zhuang W, Che Y.
    Journal: J Nat Prod; 2009 Dec; 72(12):2184-7. PubMed ID: 19919065.
    Abstract:
    The new pyrrolidinones, rigidiusculamides A-D (1-4), have been isolated from the crude extract of the ascomycete fungus Albonectria rigidiuscula. The structures of these compounds were elucidated primarily by NMR experiments. The absolute configuration of the 3,4-diol moieties in 1 and 4 was assigned using Snatzke's method. Compounds 1 and 2 showed modest cytotoxicity against the human tumor cell lines HeLa and MCF-7.
