    Daphniyunnines A-E, alkaloids from Daphniphyllum yunnanense.[Pubmed: 16643024 ]

    METHODS AND RESULTS:
    The first chemical study on the stems and leaves of Daphniphyllum yunnanense led to the isolation of five new alkaloids, Daphniyunnine A, Daphniyunnine B, daphniyunnine C, daphniyunnine D, daphniyunnine E (1-5). Daphniyunnines B-E (2-5) are four unusual C-22 nor-Daphniphyllum alkaloids.
    CONCLUSIONS:
    The structures of these alkaloids were characterized by spectroscopic methods, especially 2D NMR techniques. A single-crystal X-ray diffraction analysis was used to confirm the structure of 1. Daphniyunnine D (4) showed cytotoxicity against two tumor cell lines, P-388 and A-549, with IC(50) values of 3.0 and 0.6 microM, respectively.
