Synthesis of Novel Murrapanine Analogues by Microwave Irradiation

Aerobic oxidation of indole carbinols using Fe(NO3)3·9H2O/TEMPO/NaCl as catalysts

A practical aerobic oxidation of indole carbinols using Fe(NO3)3·9H2O/TEMPO/NaCl in DCE at room temperature and atmospheric pressure of oxygen affording aldehydes or ketones in good to excellent yields was developed. Furthermore, when using the industrially favored solvent toluene instead of DCE and air instead of pure oxygen, this protocol also works smoothly, demonstrating its high potential for possible industrial application.

Design, synthesis and 3D-QSAR study of cytotoxic flavonoid derivatives

Three series of flavonoid derivatives were designed and synthesized. All synthesized compounds were evaluated for cytotoxic activities against five human cancer cell lines, including K562, PC-3, MCF-7, A549, and HO8910. Among the compounds tested, compound 9 d exhibited the most potent cytotoxic activity with IC(50) values of 2.76-6.98 μM. Further comparative molecular field analysis was performed to conduct a 3D quantitative structure-activity relationship study. The generated 3D-QSAR model could be used for further rational design of novel flavonoid analogs as highly potent cytotoxic agents.
