요약In this work, we present novel contributions to the field of targeted protein degradation (TPD). We explore three areas of TPD: Proteolysis Targeting Chimeras (PROTACs), Autophagy-Tethering Chimeras (ATTECs), and Molecular Glue Degraders (MGDs). In the first section, we report our investigation and characterization of a dual degrader PROTAC that targets MDM2 and GSPT1/2. We also explore the use of novel E3 ligase ligands to degrade MDM2. In the second section of this work, we report our efforts to validate a TRIM24 PROTAC as well as the discovery of our own, more potent TRIM24 degrader. Next, we present our investigation of ATTECs and the utility of LC3B as an effector of autophagy-mediated TPD. Our findings suggest that the reported LC3B ligand does not interact with LC3B and may induce a degradation phenotype by other means. In the fifth chapter, we return our focus to PROTAC development focused on the target BTK. Herein, we report the development and characterization of novel BTK PROTACs that utilize an achiral ligand and a benzimidazole ligand for the recruitment of the E3 ligase CRBN. Lastly, we briefly discuss our foray into target-focused discovery of MGDs. In particular, we focus on MDM2 and BTK as targets and identify some MDM2-targeting compounds with unique activity that warrant further investigation.Overall, this work reports the novel activity of a previously reported MDM2 degrader as well as novel and effective PROTACs for TRIM24 and BTK. We also discuss our efforts to rationally design and study ATTECs and MGDs.
