Computational Chemistry (Prof. Jiande Gu) In the field of Computational Chemistry, the area of interest includes: Nature of chemical bonds Theoretical prediction of molecular potential energy surfaces Structures and properties of classical and non-classical DNA and RNA TOP Biomolecular Simulations (Prof. Jianhua Shen) High-end computing for biomedical molecule complex system. Study function relevant motion of protein and protein complex by using molecular dynamic simulations to reveal how the protein works at atomic level. Analyzing protein ligand interactions by using steer molecular dynamics and free energy simulations. Anti-diabetes lead compound discovery based on the structure of peroxisome proliferator-activated receptor. TOP Computer-Aided Drug Design and Chemoinformatics (Associate Prof. Xiao Min Luo) 1. Drug design (1). Inhibitors of Receptor Tyrosine Kinase Protein tyrosine kinase (PTK) plays a very important role in the signal tranduction path of cell, and it can regulate cell growth, prolife and differentiation etc. process. Receptor tyrosine kinase (RTK) are a class of PTK, they are transmembrane glycoprotein from their structure. RTK are constructed by ligand binding domain in the extramembrane, transmembrane domain and tyrosine kinase domain. Binding with ligand, RTK can dimerization and autophosphorylation, then tyrosine kinase activation was actived. RTK active its downstream pathway by catalyzing the phosphorylation of signal protein. RTK are important to normal physicological process and chemobiological process of cell, however, misfunction of RTK may result in many disease include cancer. We can cure cancer with inhibitors of RTK. (2). Inhibitors of HIV-1 Reverse Transcriptase (3). Inhibitors of HIV-1 Integrase 2. Target Database Building 3. Virtual Combinatorial Library Design The Combinchem we are currently developed is a program aimed to assist focus combinatorial library design.
