  Activated carbon/Brønsted acid-promoted aerobic benzylic oxidation under “on-water” condition: Green and efficient synthesis of 3-benzoylquinoxalinones as potent tubulin inhibitors

  摘要：

  Green chemistry is becoming the favored approach to preparing drug molecules in pharmaceutical industry. Herein, we developed a clean and efficient method to synthesize 3-benzoylquinoxalines via activated carbon promoted aerobic benzylic oxidation under "on-water" condition. Moreover, biological studies with this class of compounds reveal an antiproliferative profile. Further structure modifications are performed and the investigations exhibited that the most active 12a could inhibit the microtubule polymerization by binding to tubulin and thus induce multipolar mitosis, G2/M phase arrest, and apoptosis of cancer cells, In addition, molecular docking studies allow the rationalization of the pharmacodynamic properties observed. Our systematic studies provide not only guidance for applications of O-2/AC/H2O system, but also a new scaffold targeting tubulin for antitumor agent discovery.
