Abstract:
Our investigation of the stem of Dendrobium pulchellum resulted in the isolation of four known bibenzyls, chrysotobibenzyl (1), chrysotoxine (2), crepidatin (3) and moscatilin (4). The present study reveals for the first time the ability of these four compounds to facilitate anoikis and inhibit the growth of lung cancer cells in anchorage-independent condition. The preliminary data obtained disclose the inhibitory effect on cancer cell metastasis of the isolated compounds, and provide an important new approach for cancer drug development.
