Research in our group will focus on the general areas of reaction development and chemical synthesis. Our studies will be driven by the discovery of new and useful catalysts. By virtue of the developed organic reactions various organic ligands are synthesized and used as probes in biological progress. Brief summaries of three research directions illustrating these objectives are shown below.

The preparation of heterogeneous catalysts:
The preparation of the nano-particles of various metals and metal oxides will be investigated and the prepared different nano-particles are used in various organic reactions to search novel catalysts. Also, the supramolecular crystal engineering adjusted by different organic ligands is carried out to construct functional frameworks. On the basis of these assembled frameworks various heterogeneous catalysts were prepared via encapsulation of metal nano-particles. Harnessing these novel catalysts the powerful reactions and the synthetic methodologies will be a major focus. This direction is the mainstream in our research group.

The theoretical calculation for the mechanism of organic reactions:
The molecular orbit calculation on the basis of the first principle is performed to understand the influences of electronic effect, steric hindrance and solvent effect on the catalytic activity, reactivity and stereoselectivity of organic reactions. The calculation result will help us with the prediction to the reaction process and the recognition to the reaction mechanism. In combination with the modeling calculation of molecular kinetics, the molecular obit calculation is also employed to explore the molecular mechanism of HIV transcription and to provide 3 D structural models of organic ligands which will be potential inhibitors for HIV transcription.

The application of organic ligands as probes or inhibitors to explore the molecular mechanism of HIV transcription:
Collaboration with biologists the molecular mechanism of HIV transcription are investigated. Recent biological research showed that the formation of the complex between lysine-acetylated viral trans-activator(Tat-AcK50) and the human transcriptional co-activator (PCAF BRD) plays a crucial role in the HIV transcription. Taking this complex as a target position, we are going to design and sythesize a series of organic small molecules and assay the binding affinity and the binding selectivity between the complex and the corresponding small molecule via biological assay techniques to explore the effect of the binding between Tat-AcK50 and PCAF BRD on the HIV transcription and recognize the molecular mechanism of HIV transcription, finally attempting to screen out the small molecular inhibitors which can bind to the host cells.
