Dr. René C.-Gaudreault, l. pharm., PhD, is a senior researcher at the Centre de recherche du CHU de Québec-Laval University. He is the director of a medicinal chemistry laboratory based at the Hôpital Saint-François d’Assise. In addition, he is a full professor in the Department of molecular medicine at the Laval University School of Medicine. Dr. C.-Gaudreault is the author and coauthor of over 100 publications in peer-reviewed journals, and the inventor and co-inventor of numerous patents. He is the recipient of several prizes and distinctions, notably the Frisen-Rygel Medal for an outstanding Canadian academic discovery leading to uniquely positioned commercialization opportunities. His research programs mainly focus on the design and development of new anti-inflammatory, antipsoriatic, and anticancer drugs for personalized therapies.

Development of new anticancer and anti-inflammatory drugs for personalized medicine

Cancer and inflammation-based diseases are major health concerns in Canada and worldwide. Despite important medical breakthroughs over the past 75 years, few treatments are efficient and devoid of deleterious effects. Consequently, new drugs and treatments are required to improve both the quality of life and the life expectancy of patients. It is in this context that Dr. Gaudreault’s laboratory is involved in the drug design and development of new anticancer agents and their prodrugs, and non-steroidal anti-inflammatory agents exhibiting suitable biopharmaceutical and pharmacodynamic properties for preclinical and clinical studies. In addition, Dr. Gaudreault’s team is involved in the determination of their mechanisms of action and their potential therapeutical applications, using various cellular and molecular pharmacology approaches to support the design and the optimization of the next generations of molecules. Dr. Gaudreault’s research programs involve several interrelated and complementary disciplines, including molecular design and modelling, medicinal chemistry, cell biology, molecular pharmacology, and animal experimentation. The outcomes of these projects will contribute to new and efficient drugs for applications in personalized medicine.
