Dr. Sébastien Fortin PhD is a regular researcher at the Centre de recherche du CHU de Québec-Laval University, Director of a pharmaceutical chemistry laboratory located at the Hôpital Saint-François d’Assise, and Associate Professor at Laval University’s School of Pharmacy. He is author and co-author of 28 publications and co-inventor of 3 patents on the technologies that he develops. Dr. Fortin is the recipient of several awards and honors, including the Jean-François St-Denis Fellowship in Cancer Research from the Canadian Institutes of Health Research (CIHR) and the 2011 award for the best doctorate in cotutelle awarded by the Ministère des Relations internationales and the Consulat général de France à Québec. His research focuses on the design and development of new anticancer agents for use in personalized medicine.

Development of new drugs for personalized cancer chemotherapy

In Canada, cancer is the leading cause of death, followed only by cardiovascular diseases. Cancer is therefore a major public health problem. Despite recent medical breakthroughs, the ability to cure all cancer patients remains elusive. Consequently, we need to develop new treatments that will be more efficient, and more selective against cancer tumors, with the aim of improving the life expectancy and the quality of life of cancer patients. The aim of my research program is to design and prepare new anticancer agents exhibiting optimal biopharmaceutical and anticancer properties suitable for preclinical and clinical studies. My research themes are divided in two parts: 1) development of new inhibitors of DNA repair and replication mechanisms and 2) development of new inhibitors targeting cells deficient in homologous recombination. My research programs involve and focus on several interrelated and complementary disciplines, including molecular design and modeling, medicinal chemistry, cell biology, molecular pharmacology, and animal experimentation. The outcomes of these projects will contribute to the development of new, efficient and personalized anticancer treatments.
