Dr. Xue-Long Sun

Dr. Sun¡¯s laboratory is working in Medicinal and Pharmaceutical Chemistry and Chemical Biology area.

We are interested in cell surface and receptors¡¯ glycosylation patterns and changes under pathological pathways. One major research project is developing novel chemical probes and enzyme inhibitors to profile and modulate sialylaion and desialylation of receptor proteins in immune cells, including monocytes and macrophages related to infection, immune response and inflammation. The long-term goal of this research is to discover the sialylation molecular mechanisms in infection, immune response and inflammation and identify novel targets and lead compounds for antiviral infection and anti-inflammation drug development for flu and coronavirus infection and sepsis.

In addition, we are interested in biomimetic synthesis of native biomolecule thrombomodulin (TM) for the compensation of its loss in the pathological site, as an on-demand anticoagulant and anti-inflammatory therapeutic strategy. Specifically, we are developing TM-liposome conjugates that mimic the native endothelial antithrombotic mechanism of both TM and lipid components and thus will provide a more forceful antithrombotic agent. Also, we are developing TM-glycosaminoglycan (GAG) conjugates and investigating the significance of GAG on the antithrombotic activity and pharmacokinetic properties of TM.

Furthermore, we are developing biomimetic glycoligands for microarray, carbon nanotube, quantum dot and liposome surface functionalization for biosensor and drug delivery applications. In particular, we are making macro-glycoligands with native glycans in native linkage, in controlled density and orientation for both specificity and affinity.
