Synthesis and Biological Evaluation of 1,4-Diaryl-2-azetidinones as Specific Anticancer Agents: Activation of Adenosine Monophosphate Activated Protein Kinase and Induction of Apoptosis
4-diaryl-2-azetidinones were synthesized and evaluated for antiproliferative activity, cell cycle effects, and apoptosis induction. Strong cytotoxicity was observed with the best compounds (±)-trans-20, (±)-trans-21, and enantiomers (+)-trans-20 and (+)-trans-21, which exhibited IC50 values of 3–13 nM against duodenal adenocarcinoma cells. They induced inhibition of tubulin polymerization and subsequent
