Jun Wang, PhD Assistant Professor, Pharmacology and Toxicology Research in the Wang Laboratory is directed towards developing antivirals targeting drug-resistant viruses and emerging viruses, including influenza A and B viruses, enterovirus D68 (EV-D68), EV-A71, coxsackievirus, and polio virus. We are developing inhibitors against multiple viral proteins and use them as chemical probes for target validation. For influenza virus, we have developed inhibitors targeting the M2 proton channel, the viral polymerase PA-PB1 protein-protein interactions, and the hemagglutinin fusion protein. For enteroviruses, we have designed inhibitors targeting the viral capsid VP1 protein, the viral 2A protease, the viral 2C protein, and the viral polymerase. In addition, we are also interested in developing host-targeting antivirals as a means to address drug resistance.
Techniques implemented in the Wang laboratory include but not limited to structure-based drug design, high-throughput screening, medicinal chemistry, electrophysiology, peptide chemistry, biophysics and virology. We are a diverse group and researchers in the Wang Lab have opportunity to explore all aspects of pre-clinical drug discovery in the same lab starting from molecular-level design to in vivo animal model studies.

Current Research in the Wang Laboratory Covers the Following Areas:
- Discovery of broad-spectrum antivirals targeting influenza viruses, especially multi-drug resistant influenza viruses. Currently, the Wang lab is exploring both viral proteins and host factors as antiviral drug targets. As an example, the rationally designed first-in-class AM2-S31N inhibitors have shown potent antiviral activity against multiple human influenza A strains, including the ones that are resistant to oseltamivir. In another example, the Wang lab has identified several host-targeting antivirals from a high-throughput screening campaign, and they have shown broad-spectrum antiviral activity against both influenza A and B strains with mechanisms distinct from that of known antiviral drugs. These novel hits will not only lead to the discovery of new antiviral drug targets but also serve as tool compounds to help understand the mechanism of drug resistance.
- Drug discovery targeting the influenza virus polymerase complex. The influenza virus polymerase complex is highly conserved and it is a high profile antiviral drug target. From in silico screening, the Wang lab has identified several interesting lead compounds that target the polymerase complex. The hit compounds have shown broad-spectrum antiviral activity against both influenza A and B viruses and have displayed a high genetic barrier to drug resistance. In addition, we recently developed the split-luciferase complementation (SLC) assay for the detection of interaction between influenza polymerase PA-PB1 subunits. Using this assay in a pilot screening, we identified multiple hits with broad-spectrum antiviral activity. We are currently pursuing in vivo mouse model studies with the advanced lead compounds.
- Antiviral drug discovery targeting emerging and re-emerging viruses such as enterovirus, coxsakievirus, and polio virus. Taking advantage of the antiviral drug discovery platform they have built through the studies of influenza viruses, the Wang lab is transforming this platform to discover both direct-acting antiviral and host-targeting antiviral for enteroviruses including enterovirus D68 (EV-D68), EV-A71, coxsackievirus, and polio virus. We recently made progress in targeting the VP1 capsid protein, 2A protease, 2C protein and the viral polymerase of EV-D68.
- Understanding the mechanism of drug resistance. Many antiviral drugs fail because of drug resistance. Therefore, it is imperative to understand the mechanism of drug resistance and device countermeasures before resistance emerges. In this regard, a significant amount of work is devoted in studying the mechanism of resistance and the consequence of drug resistance. We hope the understanding of drug resistance will help us develop antiviral drugs with a higher genetic barrier to drug resistance. Our primary strengths are medicinal chemistry and pharmacology. We collaborate with computational chemists and structural biologists to help us achieve molecular level understanding of drug action.
