Structure-Activity Relationship Studies of Chalcones and Diarylpentanoids with Antitumor Activity: Potency and Selectivity Optimization.

We previously reported that chalcone () and diarylpentanoid () induced p53-dependent growth inhibitory activity in human cancer cells. Herein, () and () analogues were designed and synthesized in order to obtain more potent and selective compounds. Compounds , , , , and - caused pronounced in vitro growth inhibitory activity in HCT116 cells (0.
