Research in the Wang group aims to answer fundamental questions that lie at the interface of organic chemistry and chemical biology. We will develop small-molecule based probes and methods to understand genes and pathways of importance to the treatment of cancer and neurodegenerative disorders. Towards this end, we will exploit an interdisciplinary approach that integrates the principles of organic synthesis, medicinal chemistry, molecular labeling, assay development, molecular and cell biology through our studies in the following areas.

(1) New methods for the synthesis and study of bioactive nitrogen-containing molecules.

The importance of nitrogen-containing molecules is evident in biomedical research and drug discovery. Rapid and efficient preparation of structurally diverse nitrogen-containing skeletons is of the utmost importance, as is the ability to understand their biology, pharmacology and potential as chemical probes and drug candidates. Our research undertakes a novel strategy that exploits the unique and diverse reactivity of heteroatom-nitrogen bonds to design new C–N bond formation reactions. Molecules generated through these transformations are versatile and useful; they can be used in late-stage synthesis to directly afford bioactive molecules, can be subject to a wide variety of chemical reactions to quickly establish complex bioactive structures, or can be used as imaging agents for understanding biological activity and potential of targeted nitrogen-containing skeletons, all of which are closely tied to our longer-term goal of developing new chemical tools.

(2) New chemical strategies and tools for molecular labeling and imaging.

Another research focus in the Wang lab is to develop new imaging strategies and probes to advance understanding of important biological pathways and genes for the treatment of human disease. Towards this end, we have been exploiting two strategies to advance the capacity and application of molecular imaging: (1) development of new chemical methods for the facile introduction of valuable imaging reporters (e.g. 18F, N3, and acetylene) onto a diverse range of pharmacologically privileged skeletons, and (2) development of novel 15N-based structural motifs as molecular tags for hyperpolarization magnetic resonance imaging (HP-MRI). The interplay of these two complementary aspects will greatly expand the imaging toolbox and advance their application in basic and clinical research.

(3) Small-molecule probes and novel leads for human biology and disease.

Epigenetic modifying enzymes as novel therapeutic targets. We are interested in developing small-molecule regulators of epigenetics modifications, the new frontier in understanding and treatment of disease. For example, research will be directed towards identifying small-molecule modulators of arginine methylation and uncovering their regulatory pathways. Discovery of such molecules will provide powerful tools to interrogate the physiological roles of arginine methylation and offer potential lead molecules for novel therapies to contribute to a new era of epigenetic-based drugs.
