Research Interests

Our research interests include (i) bioorganic and medicinal chemistry, and (ii) green chemical synthesis. Specific foci are:

  • Synthesis and biological evaluations of novel organic compounds and natural product derivatives as potential anti-cancer, anti-inflammatory and neurological agents;
  • Development of recyclable, fluorous reagents and catalysts for organic transformations in water.


Research Highlight

Ref: Chondroitin 6-sulfate (CS-C) is an important glycosaminoglycan that regulates many physiological functions. To understand its mechanism of action at the molecular level, CS-C molecules of defined length are required. Though various synthetic approaches have been described, the synthesis routes are generally long (15-30 steps). Herein, we report an expedient three-step synthesis which gives CS-C disaccharide 1 and tetrasaccharide 2 in 22% and 10% overall yields (earlier reports: 3-5% overall yield for 1 and 1-2% overall yield for 2). No protecting groups were used and minimal purification was required. (Org. Lett. 2019, 21, 4559-4562).



Ref: Herein we revealed Z-(+)-isochaihulactone 1 (a natural product isolated from the root of Bupleurum scorzonerifolium) exhibited significant inhibition against MDR cancer cell lines and mice xenografts. By identifying the pharmacophore of 1, we elucidated that an affinity-driven Michael addition of the noncatalytic C247 of GAPDH controlled the “ON/OFF” switch of apoptosis through non-canonically nuclear GAPDH translocation, which bypasses the common apoptosis-resistant route of MDR cancers (Angew. Chem. Int. Ed. 2018, 57, 7040-7045).
