Wei HE, Professor

Dr. Wei He studied chemistry at the University of Science and Technology of China during 1993 to 2001. He obtained his Ph.D. in chemistry from the University of Rochester in 2007 under the guidance of Prof. Alison Frontier. After serving as a research scientist at Makoto Life Science, INC. (2007 to 2008) and Lexicon Pharmaceuticals, INC. (2008 to 2010), he joined the faculty of Tsinghua University in January 2011. He was promoted to Professor of Tsinghua University in 2017. His main research interests lies in the (nanostructure) metal catalysis and synthesis of drug molecules. Currently he serves as the associate editor for RSC Advances.

Research Interests

My group seeks to overcome current challenges in innovative drug discovery by focusing our efforts on the following two topics: (1) Metal nanocomposite catalyzed organic reaction. We use metal nanocatalysts to address important synthetic needs in fine chemicals and pharmaceuticals. Based on their controllable fabrication, we have been discovering highly efficient and selective organic transformations by effectively controlling the activity of the metal nanocatalysts. Our efforts also include the synthetic methodology of silicon containing compounds and their chemical biology applications; (2) Fragment Based Drug Discovery. We employ fragment screening and structure-based drug design towards the discovery of selective modulator of novel protein targets with low druggability (e.g. bromodomain proteins, deubiquitinases), which enables related chemical biological and early drug discovery study.

Scientific Contributions 

The 'silicon swap strategy' entails the replacement of a carbon atom by a silicon atom in a given drug molecule. Such a strategy has been conceived as a reasonable and appealing way to invent new drugs. However, the development of such a strategy has become stagnant mainly due to the lack of efficient synthetic method. We developed a series new reactions that provides easier and versatile access to silicon containing compounds, including chiral silicons. We also demonstrated that such a strategy could be employed in the discovery of investigational drug molecules. In our approach, we use a number of interdisciplinary methods including nanomaterial, organic and medicinal chemistry, as well as fragment lead discovery. Our research has significantly expand the utility of new tools in drug discovery.

Selected Achievements

1. (Nano) metal catalysis. We took advantage of well-defined metal nanoparticles and studied their Structure-Activity Relationship (SAR) in a number of reactions. We used the derived SAR to guide the rational design of metal nanoparticle catalysis for the target reactions. Along this line, we had developed optimal catalysts for selective hydrogenation reactions (J. Am. Chem. Soc. 2012, 134, 8975; ACS Catalysis, 2013, 3, 608; Chem. Comm. 2013, 49, 6843.), aerobic oxidation reactions (ACS Catalysis, 2013, 3, 478; ACS Catalysis, 2013, 3, 1681), Si-H activation reactions (Angew. Chem. Int. Ed., 2015, 54, 6918; Nano Research 2015, 8, 1365), as well as Si-C bond activation reactions (Angew. Chem. Int. Ed. 2014, 53, 5667; Synlett 2015, 26, 1145; Angew. Chem. Int. Ed. 2016, in press; Chem. Commun. 2015, 51, 17410).
2. Synthesis of silicon containing compounds. We developed efficient syntheses of α-silyl amines and β-silyl amines (Asian. J. Org. Chem. 2014, 3, 851; Chem. Comm. 2016, 52, 7862 – 7865). We also devised the syntheses of α- andβ- silyl amino acids and prepared the first silicon containing proteins.
3.  We discovered a novel small molecule inhibitor KQ72 that has the potential to precisely treat a subtype of non-small cell lung cancer (China Patent: 201510925699.7). We demonstrated for the first time the advantages of a “silicon swap” compound in preclinical studies.
