Campbell McInnes currently is Professor of Medicinal Chemistry at the University of South Carolina has 30 years of experience in the fields of synthetic organic chemistry, structural biology and computational chemistry towards the discovery and development of anti-cancer therapeutics in both academia and industry. He has been at USC for 17 years, achieving Full Professor in 2017. Prior to joining the university, Dr. McInnes was head of the structure-guided medicinal chemistry group at Cyclacel Inc in the United Kingdom, a company started by Prof. Sir David Lane, co-discoverer of the p53 protein. His current research is directed towards the discovery of small molecule protein kinase inhibitors targeting signaling and cell cycle proteins involved in tumor proliferation. Rather than blocking ATP binding, this research is focused on the development of very selective inhibitors by targeting protein-protein interactions involved in allosteric regulation of kinase activity and other non-catalytic functions of such enzymes. Furthermore, the McInnes laboratory has developed the REPLACE strategy to target PPIs more effectively in general and has validated this approach with several kinase targets. Promising compounds obtained through application of REPLACE are being developed preclinically and through Dr. McInnes’ spin-off company called PPI Pharmaceuticals, LLC created to exploit promising compounds discovered in his academic laboratory.
