The design and development of isoform-selective inhibitors of Hsp90

Speaker at Chemistry World Conference 2024 - Brian Blagg
University of Notre Dame, United States
Title : The design and development of isoform-selective inhibitors of Hsp90

Abstract:

The Hsp90 molecular chaperone is composed of four family members that play key roles in the folding of nascent polypeptides as well as the rematuration of misfolded proteins. The cytostolic chaperones, Hsp90a and Hspd0b, contribute to tumorogenesis and represent attractive targets for the treatment of cancer. Grp94 is the ER-localized paralog that is responsible for the trafficking of proteins, such as myocillin, and consequently represents an ideal target for the treatment of primary open angle glaucoma. In contrast to the inhibition of Hsp90, the molecular chaperones can be overexpressed to exhibit neuroprotective activity in animal models of neuropathy. While the Hspg0 isoforms play key roles in various diseases, the N-terminal ATP-binding site is >85% identical, making the development of selective inhibitors challenging. In this presentation, methods used to develop isoform-selective inhibitors will be disclosed as well as some of the early preclinical studies that are being pursued for translation.

Biography:

Dr. Blagg received a B.A. in Chemistry and Environmental Studies from Sonoma State University in 1994. He then went on to earn a Ph.D. in organic chemistry from the University of Utah in the laboratory of Dale Poulter. Following the completion of his Ph.D., he was a NIH postdoctoral fellow at the Scripps Research Institute, wherein he studied in Dale Boger's laboratory until 2002. 

Dr. Blagg began his independent research career as a medicinal chemistry professor at The University of Kansas, where he remained until 2017. In 2017, Dr. Blagg became the director of the Warren Family Research Center for Drug Discovery and Development at the University of Notre Dame and the Charles Huisking Professor of Chemistry and Biochemistry. His research focuses on the design, synthesis, and evaluation of HSP90 inhibitors.
