title: Synthesis and antitumor activity of some aromatic seleno lactones.
abstract: Several aromatic seleno lactones have been synthesized and shown to possess significant inhibitory activity against human colon tumor-8r cells in culture at concentrations lower than 1 mM. Although all of the compounds tested were found to be active, 5-hydroxy-3-[(phenylseleno)methyl]hydrocoumarinoctanoate (3d) and 5-hydroxy-3-[(phenylseleno)methyl]hydrocoumarindecanoate (3e) were found to be the most effective in inhibiting cell growth. In situ formation of the corresponding alpha-methylene lactones is postulated to account for the cytotoxic activity in this class of compounds.
