About our speaker

Dr. Dehua Pei is a Kimberly Professor at the Department of Chemistry and Biochemistry at the Ohio State University. He has been a faculty at OSU since 1995.

Dr. Pei obtained his B.S. degree in Chemistry from Wuhan University, China in 1986. He received his Ph.D. degree in organic chemistry from University of California, Berkeley in 1991. After receiving his Ph.D. he worked with Dr. Christopher T. Walsh at Harvard Medical School for a stint as postdoctoral fellow prior to joining the Department of Chemistry and Biochemistry at OSU in 1995.

Dr. Pei has been a pioneering researcher in his field. He was elected as a Fellow of the American Association for the Advancement of Science in 2010 for his contributions in his field of research. 

Presentation Abstract

The majority (~80%) of disease-relevant human proteins, including most of those involved in intracellular protein-protein interactions (PPIs), are undruggable by the current drug modalities, namely small molecules (MW<500) and biologics (MW>5000). I will discuss our efforts on developing molecules in the "middle space" (MW 500-2000; e.g., macrocyclic peptides) to target intracellular proteins. We first developed a combinatorial library technology to discover macrocyclic peptidyl ligands that bind to a protein target of interest with antibody-like affinity and specificity. We next discovered a family of small, amphipathic cyclic peptides as a novel class of exceptionally active cell-penetrating peptides and elucidated their mechanism of action. Finally, by integrating the two platform technologies, we have designed potent, selective, cell-permeable, and metabolically stable macrocyclic peptidyl inhibitors against a wide variety of intracellular enzymes (e.g., Pin1 and PTP1B) and PPIs (e.g., calcineurin-NFAT, CFTR-associated ligand-CFTR, K-Ras-Raf, and NEMO-IKK interactions).
