  Synthesis of novel α-santonin derivatives as potential cytotoxic agents

  摘要：

  Ten novel alpha-santonin derivatives have been synthesized as cytotoxic agents. The in vitro antitumor activity of these compounds has been evaluated against cancer cells lines. Structure-activity relationships indicate that alpha-methylene-gamma-lactone and endoperoxide functionalities play important roles in conferring cytotoxicity. The compounds 2-4, possessing the alpha-methylene-gamma-lactone group showed IC50 values between 5.70 and 16.40 mu M. Mixture of isomers 5 and 6, with the alpha-methylene-gamma-lactone and endoperoxide functionalities, displayed the greatest activity, with IC50 values between 1.45 and 4.35 mu M. The biological assays conducted with normal cells revealed that the compounds 2, 5 and 6 are selective against cancer cells lines tested. Bioactive lactones described herein and in our previous report did not cause disruption of the cell membrane in mouse erythrocytes. (C) 2010 Elsevier Masson SAS. All rights reserved.
