    This thesis consists of three separate chapters with individual projects: 1. Chapter 1: Developing a Chemical Biological Approach to Study E3 Ligase Activity: This is the main project of this thesis; this project aims to develop a novel chemical approach to study the formation of PPIs (Protein-Protein Interactions) in cells. The PPI system that is of interest is the ubiquitin proteasome system (UPS), with the aim to develop a set of chemical tools to study the biological activity of E3 ligases that have been recently discovered as potential drug targets. 2. Chapter 2: Understanding the Mechanism of PTC-209, a Potential Protein Translation Inhibitor (completed at the University of Toronto): The project aims are to better understand mechanism of PTC-209, as currently the known mechanism of PTC-209 is not strongly supported. Utilising the aminothiazole central core that is present in PTC-209 as a building block and varying the fragments to help identify what causes the activity seen in literature. 3. Chapter 3: Synthesis of a Lysine Covalent Ibrutinib Derivative (completed at the University of Toronto): This project aims to find an alternative solution to effectively inhibit BTK for treatment of B cell tumours. With the aim to alter ibrutinib’s scaffold to overcome the current ibrutinib design that results in patient relapse and is explained by the mutation of the targeted residue.
